[ovirt-users] Adding a new quota via the ovirt-shell

[nicolas]

Hi,

Is it currently possible to define a new resource quota (CPU, memory, 
storage...) via the ovirt-shell (CLI) in oVirt 3.5.3? I have listed all 
the available commands but I can't find it under any of them.


Thanks.

Nicolás

 Hi,

 I'm using oVirt 3.5.2 on a CentOS box. As far as the engine goes
 everything is working fine, except that I can't start the SPICE
 HTML5 tool for any of the installed machines I have.

 I've installed the oVirt guest agent on the VM side,
 websocket-proxy is running and port 6100 is listening on the engine
 box:

 # systemctl status ovirt-websocket-proxy
 ovirt-websocket-proxy.service - oVirt Engine websockets proxy
    Loaded: loaded
 (/usr/lib/systemd/system/ovirt-websocket-proxy.service; enabled)
    Active: active (running)

 # netstat -atpn | grep 6100
 tcp    0  0
 0.0.0.0:6100
 0.0.0.0:*   LISTEN  7227/python
 Also, I imported the CA cert (https://fqdn/ca.crt [1]) on the
 browser. However, once I run the SPICE HTML5 client from the
 userportal, all I get is an empty grey square with the two Send
 ctrl+alt+delete and Toggle messages output buttons at the bottom.
 Nothing in the logs about this issue. I tried to run it both with
 Chromium and Firefox on a linux box.


Did you tried to click on the Toggle messages output button? is
something there?
Can you please check your browser Javascript console (Ctrl+Shift+J) for 
errors?




Indeed, checking the Javascript console I discovered where the culprit 
is. This ovirt engine machine had formerly a FQDN that was changed 
afterwards (I used the .../setup/bin/ovirt-engine-rename script), so at 
installation time, SSL certs were issued for that FQDN. The 
ovirt-engine-rename script regenerated the engine certs, but seems that 
it didn't do the work for the websocket proxy, so the old FQDN cert is 
still used and a connection cannot be established with the daemon 
(logically, due to the mismatch). I can't find any documentation on how 
to regenerate the websocket proxy cert, though. Is there some script for 
that, or at least some manual way to accomplish it?


Thanks for your help.


 Is there anything that I am missing? I've run out of ideas...
  Did you enable port 6100 on the client side?. Try telnetting to the
 websocket-proxy from the workstation you're using Chromium/FF on.

  Joop

 By client side do you mean where the ovirt-engine is running? If so,
 yes, it's listening on that port. I can also telnet to that port:

 $ telnet ovirtenginebox 6100
 Trying 10.X.X.X...
 Connected to ovirtenginebox.
 Escape character is '^]'.

 Thanks


I just found out that actually there are some lines in the
ovirt-engine's log whenever I try to run the HTML5 client:

Based on an environment in 3.3.2 I solved a situation with
webSocketProxy Enabled only after original install + update thanks to
Alon advises.

See full lthread here:
http://lists.ovirt.org/pipermail/users/2013-December/018554.html [1]

Possibly it can apply to your environment too

You could do the following:

1. remove 

In /etc/pki/ovirt-engine/keys/:
websocket-proxy.key.nopass

websocket-proxy.p12

In /etc/pki/ovirt-engine/certs/:
websocket-proxy.cer

2. run setup using:

# engine-setup
--otopi-environment=OVESETUP_CONFIG/websocketProxyConfig=bool:True

and this should create websocket proxy certificates/keys in correct
way



Unfortunately not. The process seems to run:

[...]
[ INFO  ] Configuring WebSocket Proxy
[...]

But once it ends, there are no certs. Neither restarting the daemon 
works.


Thanks for the hint, anyway.


Be sure to make backups and verify better, in particular it this is a
production environment.
HIH,
Gianluca

[ovirt-users] Unexpected protocol mismatch with SPICE HTML5

[nicolas]

Hi,

I just made a fresh install of ovirt-engine (v. 3.5.3.1-1) on a CentOS-7 
x86_64 box. My previous installation had issues with the TLS certificate 
time of issue, which was successfully fixed in this version 
(https://bugzilla.redhat.com/show_bug.cgi?id=1210486). However, when 
trying to start the SPICE HTML5 client, all I can see is the grey square 
and no activity, and when clicking on Toggle messages output, the 
error message Unexpected protocol mismatch is shown.


Things done:
* ovirt-guest-agent installed on the VM
* On client side, updated browser (Firefox) to latest version (38.0) and 
/ca.crt has been imported into Firefox certs


Regarding logs on the server side, I can see the following:

I can't see any other relevant info, so I wonder if something else might

do?

I've installed the oVirt guest agent on the VM side,

Also, I imported the CA cert (https://fqdn/ca.crt [1]) on the
browser. However, once I run the SPICE HTML5 client from the
userportal, all I get is an empty grey square with the two Send
ctrl+alt+delete and Toggle messages output buttons at the bottom.
Nothing in the logs about this issue. I tried to run it both with
Chromium and Firefox on a linux box.

Is there anything that I am missing? I've run out of ideas...

 Did you enable port 6100 on the client side?. Try telnetting to the
websocket-proxy from the workstation you're using Chromium/FF on.

 Joop


By client side do you mean where the ovirt-engine is running? If so,
yes, it's listening on that port. I can also telnet to that port:

$ telnet ovirtenginebox 6100
Trying 10.X.X.X...
Connected to ovirtenginebox.

Thanks



I just found out that actually there are some lines in the 
ovirt-engine's log whenever I try to run the HTML5 client:

[ovirt-users] Setting VmPool type via ovirtsdk

[nicolas]

Hi,

I'm defining new VmPools via python code using ovirtSDK along with oVirt 
v. 3.5.3.1-1. Pool creation seems to work fine, but by default they are 
created as 'Automatic' and I need them to be 'Manual', however, I can't 
find out the SDK parameter to do this.


Is this currently possible?

Thanks.

[ovirt-users] Rebooting gluster nodes make VMs pause due to storage error

[nicolas]

Hi,

We're using ovirt 3.5.3.1, and as storage backend we use GlusterFS. We 
added a Storage Domain with the path "gluster.fqdn1:/volume", and as 
options, we used "backup-volfile-servers=gluster.fqdn2". We now need to 
restart both gluster.fqdn1 and gluster.fqdn2 machines due to system 
update (not at the same time, obviously). We're worried because in 
previous attempts, when restarted the main gluster node (gluster.fqdn1 
in this case), all the VMs running against that storage backend got 
paused due to storage errors, and we couldn't resume them and finally 
had to power them off the hard way and start them again.


Gluster version on gluster.fqdn1 and gluster.fqdn2 is 3.6.3-1.

Gluster configuration for that volume is:

Volume Name: volume
Type: Replicate
Volume ID: a2d7e52c-2f63-4e72-9635-4e311baae6ff
Status: Started
Number of Bricks: 1 x 2 = 2
Transport-type: tcp
Bricks:
Brick1: gluster.fqdn1:/gluster/brick_01/brick
Brick2: gluster.fqdn2:/gluster/brick_01/brick
Options Reconfigured:
storage.owner-gid: 36
storage.owner-uid: 36
cluster.server-quorum-type: server
cluster.quorum-type: none
network.remote-dio: enable
cluster.eager-lock: enable
performance.stat-prefetch: off
performance.io-cache: off
performance.read-ahead: off
performance.quick-read: off

We would like to know if there's a "clean" way to do such a procedure. 
We know that pausing all the VMs and then restarting the gluster nodes 
work with no harm, but the downtime of the VMs is important to us and we 
would like to avoid it, especially when we have 2 gluster nodes for 
that.


Any hints are appreciated,

Thanks.

Hi kasturi,

Thanks, it seems solved now - I haven't even realized there was a 
'Gluster Hooks' tab before you wrote!

Hi nicolas,

This issue happens if there are any conflicts between the hooks
scripts present in the servers of your cluster. Try to resolve the
conflicts of the hooks scripts by clicking on resolve conflicts button
and the you should no more be seeing these messages.

Thanks

[ovirt-users] Getting SPICE connection parameters with Python-SDK

[nicolas]

Hi,

On user portal, when users click on the "Connect" link of a VM that is 
configured to be run with "Native client" and SPICE protocol, a .vv file 
is generated with the connection parameters so the SPICE client knows 
where to connect: host, port, password, ...


Currently, is there a way to generate those parameters with the Python 
SDK? Especially the session password so it's possible to connect to the 
VM directly with a SPICE client.


Thanks.

[ovirt-users] Allow non-privileged users to use the API

[nicolas]

Hi,

I'm currently trying to use oVirt's API with a non-privileged username 
(only has UserRole over a few VMs) and when the request is made, a 400 
error is returned:



  Operation Failed
  
query execution failed due to insufficient permissions.
  


Is there a way to grant non-privileged users the ability to use API (for 
example, to list VMs where they have privileges)? What's the minimal 
permission a username needs to be granted to use the API?

[ovirt-users] Cannot create volume snapshot from illegal volume

[nicolas]

Hi,

We're running oVirt 3.6.5.3-1 and we're experiencing an issue with one 
of the VMs we have. There's one VM we'd like to make snapshots of and 
each time we try, the following error is shown in oVirt engine:


Message: VDSM host01.domain.com command failed: Cannot create volume 
snapshot from illegal volume


Same happens when trying to export the VM. I've attached logs for oVirt 
engine + VDSM of the SPM host.


Any hints on how to fix this will be very appreciated.

Regards,

Nicolás

I don't know which SDK you are using or if you are doing direct http 
requests
with your own framework, but in order for non privileged users to use 
the REST
api you need to pass the 'filter: true' header with the request. This 
will tell

the REST api to filter the results based on the users permissions.


Thanks, that worked.

I don't know if you have a solution, but I hit this on the last
upgrade. I just updated ovirt-engine-setup and ran engine-setup which
pulled in all the required packages properly.  This is the recommended
procedure from the upgrade notes.


That would work as a quick fix, but anyhow this should be fixed as most 
systems run complete system upgrades periodically.

[ovirt-users] Upgrade version problem

[nicolas]

Hi,

We're trying to upgrade oVirt engine from ver. 3.6.5.3 to 3.6.6.2. When 
calling 'yum update', following error occurs:


Error: Package: ovirt-engine-tools-3.6.5.3-1.el7.centos.noarch 
(@ovirt-3.6)

   Requires: ovirt-engine-tools-backup = 3.6.5.3-1.el7.centos
   Removing: 
ovirt-engine-tools-backup-3.6.5.3-1.el7.centos.noarch (@ovirt-3.6)

   ovirt-engine-tools-backup = 3.6.5.3-1.el7.centos
   Updated By: 
ovirt-engine-tools-backup-3.6.6.2-1.el7.centos.noarch (ovirt-3.6)

   ovirt-engine-tools-backup = 3.6.6.2-1.el7.centos

Seems ovirt-engine-tools package is not marked for update although there 
is a new version in repos (for example in [1]), 3.6.6.2. I run 'yum 
clean all' previously to update to make sure this is not a cache issue 
and did not solve the problem.


When trying to update ovirt-engine-tools separately it says ver. 3.6.5.3 
is the latest version:


  Package ovirt-engine-tools-3.6.5.3-1.el7.centos.noarch already 
installed and latest version


Could this be a repo metadata problem?

Thanks.

Re: [ovirt-users] Cannot create volume snapshot from illegal volume

[nicolas]

Hi,

No, the disk's state is OK. We've finally found a workaround which was 
creating a new disk, 'dd' the old disk to the new one within the VM, 
detach the new disk and attach it to a new VM, but still it's weird. 
We've kept the old machine in case you need to run any additional test.

[ovirt-users] Network interface profiles disappeared after upgrading to 3.6.1

[nicolas]

Hi,

We recently upgraded from 3.5.3 to 3.6.1. Everything went fairly smooth, 
however, today we realized we're facing some issues.


Users cannot add network interfaces on the User Portal to their VMs. It 
seems that when they click on "New", the "Profile" checkbox is empty so 
they cannot choose any value.


It's worth mentioning that we only upgraded the manager, not yet the 
hosts. Also, a red banner keeps popping out every few seconds with this 
error: (TypeError) __gwt$exception: : Cannot read property 'r' 
of null


It's also worth mentioning that I can add interfaces from the admin 
portal.


I don't actually know if it's related, but in the logs I see this:

2016-01-15 17:53:35,241 ERROR 
[org.ovirt.engine.core.bll.GetConfigurationValueQuery] (default 
task-165) [] Query execution failed due to insufficient permissions.

[org.ovirt.engine.api.restapi.resource.AbstractBackendResource] (default 
task-165) [] Operation Failed: query execution failed due to 
insufficient permissions.


All interfaces have the "Everyone" -> "UserProfileEditor" permission.

Is that some new permission that has to be granted in order to allow 
users see the network interfaces or is it a bug?


Thanks.

2016-02-02 11:01:52.804:INFO::No [2] Transaction manager found - if

SelectChannelConnector@0.0.0.0:54321
[INFO] Started Jetty Server
[INFO] Starting scanner at interval of 10 seconds.

 I could indeed verify it's listening on the VDSM port:


[root@host ovirt-vdsmfake]# netstat -atpn | grep 54321
tcp6   0  0
:::54321   
:::*    LISTEN 
44870/java

 So the next step is to add a fake host via REST. I used scripts
provided here [4] and I successfully added the host, however, it
starts installing all the VDSM packages as it were a normal host and
therefore it tries to start vdsmd as well, which throws an error as
the Jetty Server is already listening on the 54321 port. I shut down
the Jetty Server and allowed oVirt Manager to install all the packages
properly, then stopped vdsmd and started the Jetty Server, but
expectedly oVirt Engine fails with message "Host xxx is non
responsive", so what I actually got is a real VDSM host and not a fake
one.

 FWIW, the fake VDSM runs on a different host, ports are reacheable
from the oVirt engine, proper /etc/hosts has been added to the engine
to reach the host, and no further customization of web.xml has been
done.

 I feel like I'm missing something here. Could someone shed some light
on what's wrong?

 Thanks.

 Nicolás

[ovirt-users] Manually assign DC and Cluster to Blank template

[nicolas]

Hi,

We upgraded from oVirt 3.5 and 3.6 and deleted the Default cluster, so 
now we have the Blank template with no DC and no Cluster, thus our users 
can't use it.


Is there a way to manually set these two parameters to the current DC 
and Cluster values for the Blank template? I tried editing it but see no 
option to set them.


Thanks.

[ovirt-users] Pending events in the Tasks tab

[nicolas]

Hi,

We're using oVirt 3.6.2.6, and we're having some events not being 
cleared from the Tasks tab. I cannot confirm this is only related to 
creating VM pools, but any created VM pool remains unfinished forever in 
the Tasks tab. As you may see in the screenshot, there are events that 
were started in January and are still in the list. Concretely, the 
unfinished step is always "Finalizing".


Has this been reported on Bugzilla?

Is there a way to clear them out even manually?

Thanks.

Hi Nicolás,

Removing the default cluster should be ok, since the templates don't
bind VMs to a DC/Cluster--you should be able to specify the DC/Cluster
when creating a VM.

HTH,
Greg


Hi Greg,

I'll elaborate a bit further on the issue. I'm attaching a screenshot of 
the 'Templates' tab on the webadmin pane - As you can see, all of them 
have a Data Center and a Cluster assigned (columns 4 and 5) but the 
Blank template (because we deleted the default DC). Even if this 
template has the 'Everyone' permission, as we're granting permissions to 
our users on the Data Center, they are not able to see the Blank 
template in the list when deploying new machines in the userportal view, 
so currently they necessarily need to choose a template from the list 
which is not Blank, and that's an issue to some of them.


That's why I was wondering if there's a manual way to assign the DC and 
Cluster to the Blank template, even modifying it directly in the DB, so 
the users see it in the userportal.


Any hint is very appreciated.

Regards,

[ovirt-users] How to create a DataCenterQuota via Python SDK?

[nicolas]

Hi,

I'm trying to create a Data Center Quota with limits for memory, vcpu 
and storage. As per the class definition, DataCenterQuota expects: a 
datacenter, a quota and a context. Quota class in turn expects limits 
but only as percentages, for hard and soft limits.


However if I dump an already created DataCenterQuota object I see:

{'_Base__context': 36443152,
 'parentclass': ,
 'permissions': 
0x278ef90>,
 'quotaclusterlimits': 
object at 0x2540490>,
 'quotastoragelimits': 
object at 0x278ef50>,

 'superclass': }

I see DataCenterQuotaQuotaClusterLimits and 
DataCenterQuotaQuotaStorageLimits allow creating limits for memory/cpu 
and storage respectively, and they're set in the DataCenterQuota 
__init__ method like this:


  self.quotaclusterlimits = DataCenterQuotaQuotaClusterLimits(self, 
context)
  self.quotastoragelimits = DataCenterQuotaQuotaStorageLimits(self, 
context)


However, I'm unable to find out how to handle the 'context' parameter to 
contain those two limit classes.


Could someone shed some light on it? An example would be welcome too.

Thanks.

This is oVirt 3.6.4.1-1, and using an iSCSI-based storage backend.

I don't think so, but you can loop waiting, see e.g.:



http://www.ovirt.org/develop/api/pythonapi/#create-a-template-from-vm

I wish we could have an extra parameters on the Python SDK that would
do this exact loop for us, since essentially most use cases require
this.
I'm not sure it is relevant only for template creation, btw.
What is also more annoying, is that this loop (IIRC) will never break,
if something bad happens and the template ends up in a state != down
(such as locked).
(Same issue I've just had with host installation - Iv'e waited
endlessly for it to be in 'up' state, only to find out it ended in
'installed_failed' state).
Y.



I have had some issues related to this, I've opened a couple of BZs (for 
different issues, though):


https://bugzilla.redhat.com/show_bug.cgi?id=1245630

https://bugzilla.redhat.com/show_bug.cgi?id=1315874

Currently the "poorman's wait method" that I detailed on the second BZ 
is the method I'm following to check whether state is "Ok".

The VMs in a pool are always stateless.
There is an RFE [1] making the pools stateful, but not yet implemented.

But the reporting is not correct, we should not report they are
stateless if they are not.
Can you please open a bug for this?


Sure. Done: https://bugzilla.redhat.com/show_bug.cgi?id=1318955

We've tried to put it on maintenance but we're getting this error:

Does that mean that *all* hosts must be on maintenance to do that? 
There's nothing left on the gluster storage right now.


Thanks.

OK :-)

Only now I realized you wrote 'ovirt-event-notifier' :-)

Please do.

Actually it was never named ovirt-event-notifier. AFAICT this string 
only
ever existed in this message, probably some simple typo no-one ever 
noticed

until you did now :-)

It indeed was renamed in the past, though. It's previous name was
'engine-notifierd':

Thanks for the report!



Done. https://bugzilla.redhat.com/show_bug.cgi?id=1321583

Nir,
See attached the repoplot output.


So we have about one concurrent lvm command without any disk

everything seems snappy.

Nicolás, maybe this storage or the host is overloaded by the vms? Are 
your vms

doing lot of io?



Not that I know, actually it should have been a "calm" time slot as far 
as IOs go, nor the storage was overloaded at that time. If I'm not 
mistaken, on the repoplot report I see there are two LVM operations at a 
time, maybe that has something to do with it? (although as you say, the 
lvextend is just a metadata change...)



lvextend operation should be very fast operation, this is just a
metadata change,
allocating couple of extents to that lv.

Zdenek, how do you suggest to debug slow lvm commands?

See the attached pdf, lvm commands took 15-50 seconds.

Hi,

Our scenario is the following:

~495 VMs, of which ~120 are constantly up

   * ds1: 2T, currently has 276 disks

   ds1 and ds2 are physically the same backend which exports two 
2TB

volumes.
ds3 is a different storage backend where we're currently 
migrating some

disks from ds1 and ds2.



What the the storage backend behind ds1 and 2?




The storage backend for ds1 and ds2 is the iSCSI-based HP LeftHand

Usually, when VMs become unresponsive, the whole host where they

gets
unresponsive too, so that gives a hint about the problem, my bet 
is the

culprit is somewhere on the host side and not on the VMs side.



Probably the vm became unresponsive because connection to the host

I forgot to mention that less commonly we have situations where the

doesn't get unresponsive but the VMs on it do and they don't become
responsive ever again, so we have to forcibly power them off and 
start

them
on a different host. But in this case the connection with the host
doesn't
ever get lost (so basically the host is Up, but any VM run on them 
is

unresponsive).



When that
happens, the host itself gets non-responsive and only recoverable 
after

reboot, since it's unable to reconnect.

Hi,

Probably not an oVirt issue, but maybe someone can help. I've
deployed a pretty basic VM (ubuntu 14.04 server, 4GB RAM, 4 CPUs,
15GB storage). Each time I install an additional desktop environment
(Gnome, KDE, whatever...), CPU usage rises to 100% all time to the
extreme that interacting with the machine becomes impossible (maybe
a mouse movement is propagated 3 minutes later or so...).


Is X properly configured with QXL?
xorg-x11-drv-qxl RPM (in Fedora / EL - I assume something similar in
Ubuntu) installed, and x.org [2] CONF file properly set up - something
like:

Section "Device"
 Identifier "qxl"
 Driver "qxl"
EndSection

Section "Screen"
 Identifier "screen"
 Device "qxl"
 DefaultDepth 24
 SubSection "Display"
 Depth 24
 Modes "1024x768"
 EndSubSection
EndSection

Y.
 


Indeed, the package was installed and everything configured as should. I 
tried removing the qxl driver package from the OS and now everything 
goes smooth as silk... Strange, as supposedly this driver should 
optimize the graphics part.


Thanks all for the help!

Regards.




To debug this, I installed LXDE, which is a lightweight desktop
environment based on Xorg. I could see there is an Xorg process
consuming one of the CPUs and the machine stops responding as far as
the desktop environment goes. I have not changed anything in the
configuration file.

I could also see this only happens when QXL is chosen as the
display driver. When CIRRUS is chosen, everything works smoothly and
CPU is ~100% idle. The downside is that we want to use SPICE and
CIRRUS won't allow it.

Why does this happen? Is this an OS-side driver issue? Any hint how
can it be fixed?

Thanks.

Hi,

We're running oVirt 3.6.5.3-1 and lately we're experiencing

with
some VMs being paused because they're marked as non-responsive.
Mostly,
after a few seconds they recover, but we want to debug 
precisely

this
problem so we can fix it consistently.

Our scenario is the following:

~495 VMs, of which ~120 are constantly up
3 datastores, all of them iSCSI-based:
   * ds1: 2T, currently has 276 disks
   * ds2: 2T, currently has 179 disks
   * ds3: 500G, currently has 65 disks
7 hosts: All have mostly the same hardware. CPU and memory are
currently
very lowly used (< 10%).

   ds1 and ds2 are physically the same backend which exports 
two 2TB

volumes.
ds3 is a different storage backend where we're currently 
migrating

some
disks from ds1 and ds2.




What the the storage backend behind ds1 and 2?





The storage backend for ds1 and ds2 is the iSCSI-based HP 
LeftHand

P4000
G2.

Usually, when VMs become unresponsive, the whole host where 
they run

gets
unresponsive too, so that gives a hint about the problem, my 
bet is

the
culprit is somewhere on the host side and not on the VMs side.




Probably the vm became unresponsive because connection to the 
host

was
lost.





I forgot to mention that less commonly we have situations where 
the

host
doesn't get unresponsive but the VMs on it do and they don't 
become
responsive ever again, so we have to forcibly power them off and 
start

them
on a different host. But in this case the connection with the 
host

doesn't
ever get lost (so basically the host is Up, but any VM run on 
them is

unresponsive).



When that
happens, the host itself gets non-responsive and only 
recoverable

after
reboot, since it's unable to reconnect.




Piotr, can you check engine log and explain why host is not
reconnected?


I must say this is not specific to
this oVirt version, when we were using v.3.6.4 the same 
happened,

and
it's
also worthy mentioning we've not done any configuration changes 
and

everything had been working quite well for a long time.

We were monitoring our ds1 and ds2 physical backend to see
performance
and
we suspect we've run out of IOPS since we're reaching the 
maximum

specified
by the manufacturer, probably at certain times the host cannot
perform
a
storage operation within some time limit and it marks VMs as
unresponsive.
That's why we've set up ds3 and we're migrating ds1 and ds2 to 
ds3.

When
we
run out of space on ds3 we'll create more smaller volumes to 
keep

migrating.

On the host side, when this happens, we've run repoplot on the 
vdsm

log
and
I'm attaching the result. Clearly there's a *huge* LVM response

(~30

Re: [ovirt-users] VM has been paused due to no Storage space error.

[nicolas]

Ok, that makes sense, thanks for the insight both Alex and Fred. I'm 
attaching the VDSM log of the SPM node at the time of the pause. I 
couldn't find anything that would clearly identify the problem, but 
maybe you'll be able to.


Thanks.

Hi,

Yes, just as Alex explained, if the disk has been created as thin
provisioning, the vdsm will extends once a watermark is reached.
Usually it should not get to the state the Vm is paused.

From the log, you can see that the request for extension has been sent
before the VM got to the No Space Error.
Later, we can see the VM resuming.

Note that the extension is done on the SPM host, so it would be
interesting to see the vdsm log from the host that was in SPM role at
this timeframe.

Hi,

If you have set up VM disks as Thin Provisioned, the VM has to
pause when the disk image needs to expand. You won't see this on VMs
with preallocated storage.

It's not the SAN that's running out of space, it's the VM image
needing to be expanded incrementally each time.

Cheers

I've attached a screenshot, seems there's not.







Its highly likely the dropdown is there, but its scrolled below

the

and see



what is going on.











Okay I double checked, I went to the VMs main tab, selected a VM,
then went to



the permissions sub tab. Clicked add. The dialog that popped up
looks like the

appears to



be missing some styling, which is likely what caused the Role to

to be scrolled below the bottom of the page.







Can you complete clear your cache (not shift reload, but
settings->clear



cache). If that doesn't work can you tell us the version of the
patternfly rpm



installed on your engine?







Yes, I already did that, also opened the engine on different clients
and the behavior is the same, I believe this is not a client issue.
Patternfly package is patternfly1-1.3.0-1.el7.centos.noarch







Anyhow, I see there are lots of packages to update so I'll do so
within a few days and report results.




So I was able to update all packages, restart run engine-setup just in 
case, restart ovirt-engine and the situation is the same. I remembered 
we also have a dev. environment oVirt installation which we upgraded 
from 3.6.7 to 4.0.1 and same happens here, so finally we have 3 
independent oVirt installations with the same problem. There's something 
not working as intended.


I'm attaching a list of packages on oVirt engine and their versions if 
you want to check if there's something wrong with versioning, although 
everything seems to be ok.


Thanks!

Its highly likely the dropdown is there, but its scrolled below

the bottom



of the dialog and thus you can't see it. I thought I made sure all

the

and see



what is going on.











Okay I double checked, I went to the VMs main tab, selected a VM,
then went to



the permissions sub tab. Clicked add. The dialog that popped up
looks like the



one attached, which is what I was expecting. The one you attached
appears to



be missing some styling, which is likely what caused the Role to
Assign part



to be scrolled below the bottom of the page.







Can you complete clear your cache (not shift reload, but
settings->clear



cache). If that doesn't work can you tell us the version of the
patternfly rpm



installed on your engine?







Yes, I already did that, also opened the engine on different clients
and the behavior is the same, I believe this is not a client issue.
Patternfly package is patternfly1-1.3.0-1.el7.centos.noarch




Ok, this indeed seems like a graphics problem since I am seeing this
connecting to a machine through a VNC server and the Role combobox is
moved down out of the dialog.

However, the LDAP issue persists. When I choose the 'internal' domain, 
I
can search the 'admin' user successfully, however, if I set it to be 
the

LDAP domain, any search returns nothing.

Any hints or ideas how to debug this?


Can you please enable debug log[1] and send it here?

[1]
https://github.com/oVirt/ovirt-engine-extension-aaa-ldap/blob/master/README#L442



Thanks. I was now able to see why it is failing:

TRACE [org.ovirt.engineextensions.aaa.ldap.Framework] (default task-13) 
[] SearchRequest: Exception: LDAPSearchException(resultCode=11 (admin 
limit exceeded), numEntries=0, numReferences=0, errorMessage='admin 
limit exceeded')


Indeed, if I run that query using the ldapsearch command I can clearly 
see it is returning an "admin limit exceeded" error.


The applied filter is: 
(&(objectClass=posixAccount)(uid=*)(|(givenName=username)(sn=username)(displayName=username)(uid=username)))


Strange thing is this hasn't been an issue on oVirt 3.6.x and we've not 
changed our LDAP configuration. Has the filter been changed in 4.x by 
default?


If so, is there a way to override the filter to make it simpler? (In our 
case we'll always seek by username, so no need to search by givenName, 
sn or displayName).


Thanks.



Thanks.







Anyhow, I see there are lots of packages to update so I'll do so
within a few days and report results.

So I gave it another try and this time it worked without any issue (with 
4.0.1.1 version). Strange, maybe the first upgrade failure left system 
in a weird state? Anyhow almost everything ([1]) is working fine now. 
Thanks for the help!

Hi Martin,

Actually, up until now we had that cert configured in httpd and in
websocket proxy. Seems that now in 4.0.x it's not enough, as opening
the https://fqdn [1] complains about the cert not being imported in
the key chain.

​Yes, there's an updated procedure on using external CA in 4.0,
for details please take a look at Doc Text in

https://bugzilla.redhat.com/show_bug.cgi?id=1336838 [2]
​  
So I imported it via keytool, but I don't want to use it in the
engine <-> VDSM communication.

​Hmm, so that would imply that we have some issue with existing
internal enigne CA during upgrade ...

The strange thing is that we test upgrades a lot but so far we
haven't seen any issues which will broke

SSL setup between engine and VDSM. You said that you had to
downgrade back to 3.6.7 (so unfortunately for us we cannot
investigate your nonworking setup more), but how did you do that?

Removing all engine packages and configuration​, installing back
3.6.7 packaging and restoring configuration form backup?

I'm asking to know what changed in your setup between not working
4.0 and working 3.6.7 ...


 Indeed, those are the steps I followed to the point.

 To add more strangeness, previously to upgrading this oVirt
infrastructure, we upgraded another one that we have (also using own
cert, a different one but from the same CA) and everything went
smoothly. And what's more, previously to upgrading the engine that
failed, I created a copy of that engine machine in a sandbox
environment to see if upgrade process would or not success, and it
worked perfectly.

 The only difference between the sandbox and the real machine's
process was that when upgrading the real one, the first time I run
"engine-setup" it failed because 'systemd' reported PostgreSQL as it
was not running (actually it was, thougg), so everything rolled back.
I had to kill the PostgreSQL process, start it again with systemctl
and then run "engine-setup", where the process completed successfully
but the SSL issue appeared. Not sure if this rollback could have
shattered the whole thing...

 Anyhow, tomorrow I'm going to create another copy of the engine
machine to a sandbox environment and try again. If it works I'll cross
my fingers and give another try on the real machine...

 Thanks!

​Thanks a lot for you effort. I will try to perform same upgrade
tomorrow in my test env.
​ 


Thanks

Martin

Thanks!

you using it only for HTTPS certificate or do you want to use it

Re: [ovirt-users] 3.6 -> 4.0 upgrade fails on schema refresh

Hi Arik,

Hi,

This is a bit aggressive solution to remove all snapshots with the 
memory.


Can you confirm that a storage domain that was active while creating
the snapshot with memory was removed from the system?
This is something that was not covered and could lead to the reported 
issue.




Some of them were available when we did remove a storage backend, 
indeed. Some were newer, the problem is that I don't know which one 
actually failed since when this happened we were in a hurry and needed 
to upgrade ASAP.



Until we come up with a proper solution, you can use the following
query to identify the exact problematic snapshots and remove them
before upgrading:
select vm_name, snapshots.description as snapshot_name, snapshot_id
from snapshots join vm_static on vm_id=vm_guid where
CAST(split_part(memory_volume, ',', 1) AS UUID) not in (select id from
storage_domain_static);



Thanks. We have another oVirt infrastructure and I see this query is 
returning one row. I'll report back when we upgrade this second 
infrastructure and provide some details.


Regards.

Arik

Hi,

We have had a similar issue when upgrading, digging into it we found 
out

that this was caused by snapshots that had the "Save memory" option
enabled. We finally ended up deleting any snapshot that had this 
option
enabled and then we tried to upgrade, this time the process went 
smooth.


Hope this helps.

Regards.

[ovirt-users] IOException (error 503) when calling /ovirt-engine-reports

[nicolas]

Hi,

We just upgraded to oVirt 4.0, everything seems to be working but in our 
logs we see an exception for /ovirt-engine-reports continuously. Any 
call to /ovirt-engine-reports generates a 503 error.


I'm attaching the full exception.

Any hints?

We've upgraded our second oVirt infrastructure as well, here are the

1) I run the query you provided, it returned one row.
2) I tried upgrading to 4.0 without deleting that snapshot: it failed 
with the error below.

3) I deleted the snapshot
4) Now I tried upgrading again and everything went smoothly.

I'd say this is the same issue, apparently.

Thanks.

You need to do this in the 'engine' database instead of 'postgres'.

[ovirt-users] Limit DWH database size

[nicolas]

Hi,

Since we upgraded to 4.0.x, DWH's PostgreSQL database is getting really 
huge. Is there a clean way to limit its size, like setting a maximal 
retention time for DWH data?

Re: [ovirt-users] Limit DWH database size

[nicolas]

I tried adjusting the DWH_TABLES_KEEP_HOURLY parameter to a very low 
value and also setting the DWH_SAMPLING parameter to 60 and restarted 
both ovirt-engine-dwhd and ovirt-engine daemons, however, the database 
is still huge.


So even if I change those parameters should I manually clean up the 
database? If so, what's the recommended way?


Thanks.

El 2016-09-01 19:26, Shirly Radco escribió:

Another option is to set the DWH_SAMPLING back to 60  and restart
dwh.
 This will lower the granularity of the dashboard calculations.
 The dwh db size grow since now it samples the statistics every 15
seconds instead of once a minute.

Best regards,
 Shirly Radco

 Earlier today replied to a similar question, search list archives for
 "Change Engine History Logging from Advanched to Basic".

 Just to confirm: I already have basic DWH configured, and the content
of /etc/ovirt-engine-dwh/ovirt-engine-dwhd.conf.d/10-setup-scale.conf
is:

   DWH_TABLES_KEEP_SAMPLES=24
   DWH_TABLES_KEEP_HOURLY=720
   DWH_TABLES_KEEP_DAILY=0

 So according to [1] regarding "DWH_TABLES_KEEP_HOURLY":

   The number of hours that hourly data is stored. The default is 60
days.
   Hourly data more than two days old is aggregated into dailydata.

 if I reduce that value to say 240 (10 days), any older entry from
that should be erased upon a DWH restart, right?

[ovirt-users] Checking VmPool status with Python-SDK?

[nicolas]

Hi,

We're running oVirt 4.0.4.4 with engine python SDK version 3.6.7, and 
currently we're developing an application that first creates a VmPool 
and afterwards it updates it. However, sometimes happens that both 
operations occur at the same time, which results in an oVirt error 
claiming that a VmPool cannot be updated if there are still pending 
operations to do.


We want to control this situation, so we've checked if the VmPool class 
has a .get_status() method but it seems it doesn't, so I'm asking for 
alternative ways of handling this. Would it be enough to say a VmPool is 
not "busy" if all its VMs are not in a blocked state (for example, with 
a blocked disk due to clonation)?


Thanks.

[ovirt-users] Change storage domain description

[nicolas]

Hi,

How can I change an existing storage domain's description? When 'Manage 
Storage is clicked, only the name can be changed but both Description 
and Comment fields are greyed-out.


This is oVirt 4.0.3 BTW.

Hi,

We've recently upgraded from oVirt 4.0.x to 4.1.0 and it seems that
the
behavior of a script we wrote in Python-SDK has changed slightly.
We
have a script that needs to be executed forever (daemon mode). This
daemon creates an ovirtsdk4.Connection object and uses the same
Connection object all the time.

conn = sdk.Connection(
  url=URI,
  username=USERNAME,
  password=PASSWORD,
  ca_file=CAFILE
)

Between iterations we have ~5 minutes delays which we accomplish
with a
time.sleep(...) call.

After some of these iterations (5 or 6), when trying to perform an
operation on the Connection object (in this case, listing all SDs):

    try:
        sys_serv = conn.system_service()
        sd_serv = sys_serv.storage_domains_service()
        storages = sd_serv.list(search=sd_search_query)
    except Error, e:
        log('ERR: Error getting storage domains: %s' % (e))

We start getting exceptions (i.e., the sd_serv.list() call throwing
an
Error exception) with this message:

    ERR: Error getting storage domains: HTTP response code is
401.

I believe this has something to do with the Connection object
expiring
(even if it's not idle more than 5 minutes at any time). Is there a
way
to "refresh" the Connection object so it doesn't auto-logout
(assuming
this is the actual problem)?

As I said, this started happening as of oVirt 4.1.0.
ovirt-engine-sdk-python version is 4.1.1.

Any ideas?

This sound like this bug, opened yesterday:

  SSO token used for the API expires when running only queries
  https://bugzilla.redhat.com/1434605 [1]

But I thought the same happened in 4.0. Can you confirm that you
don't
see this problem in 4.0?

Open possible workaround is to force a refresh of the backend
session
sending an external event, like in this example:



https://github.com/oVirt/ovirt-engine-sdk/blob/master/sdk/examples/vm_backup.py#L112-L131

[2]

I also think that we need to modify the SDKs so that they detect
expired
SSO tokens and renew them automatically. I will open another bug
for that.

If you're planning to do it that way, make sure you install version 3.x

Re: [ovirt-users] Python-SDK4: How to list VM user sessions?

[nicolas]

Hi Giulio,

I tried to reproduce your same steps and it returns an non-empty list 
for me.


In [1]: vms_serv = sys_serv.vms_service()

In [2]: vm = vms_serv.list(search='name=bleh')[0]

In [3]: vmsv = vms_serv.vm_service(vm.id)

In [4]: vmsess = vmsv.sessions_service()

In [5]: vmsess.list()
Out[5]:
[,
 ]

Are you sure a session is initiated on vmname in the moment you run the 
vms_service.list(...)[0] statement?

sessions = vm_service.sessions_service().list()

But "sessions" is None.

Same result using:

"s" is None.

I tried also using curl, and if I connect to:

https://my.ovirt.host/ovirt-engine/api/v4/vms//sessions

I get a beautiful 404.

Also using v3 of python SDK I obtain the same behaviour.

So I suspect that retrieving user sessions via API is not implemented,
is it? If not, what I'm doing wrong?

I'm using RHV 4.0.6.3-0.1.el7ev

Hi,

I'm trying to get a user's list of permissions, i.e., list all
permissions a user have on VMs and VmPools.

In SDK3 that was easy as I could run (being 'u' a User object):

for perm in u.permissions.list():
vm = perm.get_vm()
vmpool = perm.get_vmpool()

if vm or vmpool:
print "User has some permissions!"

In SDK4 I cannot reproduce the same logic. u.permissions returns an
empty list ([]).

What I have so far is something like this:

for u in users_serv.list():
 if u.user_name == 'admin@internal':
 continue

 vms_service = sys_serv.vms_service()
 for vm in vms_service.list():
 vms = vms_service.vm_service(id=vm.id)
 ps = vms.permissions_service()
 for perm in ps.list():
 perm_service = ps.permission_service(id=perm.id)
 getperm = perm_service.get()
 if getperm.user.user_name == u.user_name:
 print "Permission for %s" % (u.user_name)
 if getperm.vm:
 print "VM: %s" % (getperm.vm.id)
 if getperm.vm_pool:
 print "VmPool: %s" % (getperm.vm_pool.id)

However, this seems a bit overkill. We have nearly 850 VMs and for a
single user this takes about 25 minutes to run. Additionally, it 
doesn't

seem to return any permission, although I know this user has some
permissions over 2 VMs (not sure where is it messed up).

I also tried using the system_service.permissions_service() but it 
seems

to return only the global permissions.

Is there an easier way to do this?

Thanks!


Version 4 of the SDK makes a clear distinction between what are pure
containers of data (like the User class) and what are services (like 
the

UsersService class). Therefore when you call 'u.permissions' in version
4 of the SD you get nothing, because the object that you retrieved
previously doesn't contain the permissions, only a link. That is 
exactly

how the API behaves. When you do this:

  GET /ovirt-engine/api/users/{user:id}

You only get the data of the user, and some links to other related 
data,

like the permissions:

  
myuser
...

  

In version 4 of the SDK the simple way to follow the link is to use the
Connection.follow_link method. So, you need something like this:

---8<---
# Find the user:
users_service = connection.system_service().users_service()
user = users_service.list(search='name=myuser')[0]

# Follow the link to the permissions of the user:
perms = connection.follow_link(user.permissions)
for perm in perms:
if perm.vm or perm.vm_pool:
print "User has some permissions!"
--->8---


Thanks, that makes things much easier!

KiB and that oVirt has its values as MB in the webadmin, but when I sent 
this message the difference was quite more significant (1024MB of 
minimum guaranteed and about 640K KiB on the VM).


It's also true that meanwhile we upgraded from 4.0.2 to 4.1.1 and this 
time I couldn't reproduce it anymore.


If at some point I am able to reproduce it again, I'll send detailed 
logs of the issue.


Thanks.

Hi,

I don't really know if this question is suitable on this list, as I 
doubt it's an oVirt bug, neither I know if it shall be considered a 
bug.


We recently run a VM on a host that was memory over-used (around 80% 
of usage). The VM booted correctly, then we run "top" and saw how 
physical RAM started decreasing every two seconds. At first it was 
4GB, then less and less until it stabilized at around 600MB.


Based on this (correct me if I'm wrong), we believe this is an effect 
of having this VM with ballooning enabled, as it does exactly this: 
It adds/removes RAM depending on host decision. Thing is that this VM 
had a minimal guaranteed RAM of 1GB, so even if this happened due to 
ballooning, I'm not sure if it should have honored the minimum 
guaranteed RAM.


When this happened, we run a 'ps' to see with what options the qemu 
process was invoked, and parameters seemed correct (that's why I 
don't know if it should be posted here or even if it's a bug).


It does belong here, it’s a different component doing it “externally” 
to the qemu process- mom.




Is this the expected behavior?


min guaranteed should be respected, adding mom maintainer Martin

[ovirt-users] Python-SDK4: How to list user permissions?

[nicolas]

Hi,

I'm trying to get a user's list of permissions, i.e., list all 
permissions a user have on VMs and VmPools.


In SDK3 that was easy as I could run (being 'u' a User object):

for perm in u.permissions.list():
vm = perm.get_vm()
vmpool = perm.get_vmpool()

if vm or vmpool:
print "User has some permissions!"

In SDK4 I cannot reproduce the same logic. u.permissions returns an 
empty list ([]).


What I have so far is something like this:

for u in users_serv.list():
 if u.user_name == 'admin@internal':
 continue

 vms_service = sys_serv.vms_service()
 for vm in vms_service.list():
 vms = vms_service.vm_service(id=vm.id)
 ps = vms.permissions_service()
 for perm in ps.list():
 perm_service = ps.permission_service(id=perm.id)
 getperm = perm_service.get()
 if getperm.user.user_name == u.user_name:
 print "Permission for %s" % (u.user_name)
 if getperm.vm:
 print "VM: %s" % (getperm.vm.id)
 if getperm.vm_pool:
 print "VmPool: %s" % (getperm.vm_pool.id)

However, this seems a bit overkill. We have nearly 850 VMs and for a 
single user this takes about 25 minutes to run. Additionally, it doesn't 
seem to return any permission, although I know this user has some 
permissions over 2 VMs (not sure where is it messed up).


I also tried using the system_service.permissions_service() but it seems 
to return only the global permissions.


Is there an easier way to do this?

Thanks!

[ovirt-users] Python-SDK: ovirtsdk4.Connection object autologout?

[nicolas]

Hi,

We've recently upgraded from oVirt 4.0.x to 4.1.0 and it seems that the 
behavior of a script we wrote in Python-SDK has changed slightly. We 
have a script that needs to be executed forever (daemon mode). This 
daemon creates an ovirtsdk4.Connection object and uses the same 
Connection object all the time.


conn = sdk.Connection(
  url=URI,
  username=USERNAME,
  password=PASSWORD,
  ca_file=CAFILE
)

Between iterations we have ~5 minutes delays which we accomplish with a 
time.sleep(...) call.


After some of these iterations (5 or 6), when trying to perform an 
operation on the Connection object (in this case, listing all SDs):


try:
sys_serv = conn.system_service()
sd_serv = sys_serv.storage_domains_service()
storages = sd_serv.list(search=sd_search_query)
except Error, e:
log('ERR: Error getting storage domains: %s' % (e))

We start getting exceptions (i.e., the sd_serv.list() call throwing an 
Error exception) with this message:


ERR: Error getting storage domains: HTTP response code is 401.

I believe this has something to do with the Connection object expiring 
(even if it's not idle more than 5 minutes at any time). Is there a way 
to "refresh" the Connection object so it doesn't auto-logout (assuming 
this is the actual problem)?


As I said, this started happening as of oVirt 4.1.0. 
ovirt-engine-sdk-python version is 4.1.1.


Any ideas?

Thanks.

Re: [ovirt-users] Python-SDK: ovirtsdk4.Connection object autologout?

[nicolas]

Hi Juan,

I confirm this was working with 4.0.6 (but the same SDK package). The 
script is relatively new but I'm 100% sure it has been in execution for 
several weeks, in contrast to current version where after 5-6 iterations 
the exception starts showing up.


I've voted for the bug and added myself as CC.

Thank you.

Regards,

Nicolás

This sound like this bug, opened yesterday:

  SSO token used for the API expires when running only queries
  https://bugzilla.redhat.com/1434605

But I thought the same happened in 4.0. Can you confirm that you don't
see this problem in 4.0?

Open possible workaround is to force a refresh of the backend session
sending an external event, like in this example:


https://github.com/oVirt/ovirt-engine-sdk/blob/master/sdk/examples/vm_backup.py#L112-L131

I also think that we need to modify the SDKs so that they detect 
expired
SSO tokens and renew them automatically. I will open another bug for 
that.




Here is the bug for adding automatic SSO token renew to the SDK, in 
case

you want to follow/vote it:

[ovirt-users] Python-SDK4: Listing template by ID throws exception

[nicolas]

Hi,

I'm using ovirt-engine-sdk-python 4.1.3 (ovirt ver is 4.1.0), and in a

tpl_serv = sys_serv.templates_service()

t = tpl_serv.list(search='id=fedff75f-635f-4790-9bbf-2ac389e14f93')

And it throws:

This should work, or at least it shouldn't generate that error. But it
isn't the best way to get a template (or any object) if you already 
know

the id. It is better to do this:

  conn = ovirtsdk4.Connection(...)
  sys_serv = conn.system_service()
  tpls_serv = sys_serv.templates_service()
  tpl_serv =
tpls_serv.tmeplate_service('fedff75f-635f-4790-9bbf-2ac389e14f93')
  tpl = tpl_serv.get()


Thanks Juan, this way it worked.

[ovirt-users] Storage balancer project

[nicolas]

Hi,

I implemented a storage domain balancer [1], i.e. a script that tries to 
keep all storage domains under a defined threshold. We use our oVirt 
infrastructure for teaching so have several hundreds of users and cca. 
800 VMs at this time, so something like this is really needed 
considering that when students create their VMs they tend to create 
their disks under the same storage domain (normally the first available 
one). This results in one or two heavily used SDs and the rest 
underused.


I tried to keep it as simple as possible and doesn't have many features, 
but it seems to work (I tried it under our conditions: About 10 SDs, 
relatively highly used). If someone want to improve something on it, 
pull requests are welcome.


Might also be an inspiration on [2].

Is it replaced by something you may run in your environment? Are there
other packages pending upgrade?



Ok, indeed Chef is doing weird things as even if the package is
installed, it's reinstalling it everytime it runs.



To be more specific, all our configuration is managed with Chef. Up 
until this vdsm version (4.19.15-1.el7.centos.x86_64), vdsm had a 
dependency to 'ntp'. As of now, the dependency was changed to chrony (a 
logical change BTW). So our chef configuration was forcing installing 
ntp, which uninstalled vdsm for dependencies and then it reinstalled 
vdsm, but unconfigured.

with error code 1).


-

I run the 'vdsm-tool configure --force' command, it ends successfully 
and after that I can start the vdsmd process. But... after a while it 
fails again and I need to re-run the same command all the time.


Is this a known bug? any temporary workaround?

Versions:

vdsm-4.19.15-1.el7.centos.x86_64
libvirt-2.0.0-10.el7_3.5.x86_64

Thanks.

Re: [ovirt-users] Python-SDK4: Managing accents?

[nicolas]

Currently all our scripts are python2-based, not sure if running them 
with Python3 would need a major change, but currently we're happy with 
Python2. I'm still not clear if this is a bug or an additional option 
should be supplied in order to make this work.


Thanks.

Hi,

We're running Python SDK (ovirt-engine-sdk-python) ver 4.1.4 and we're

   users_service = connection.system_service().users_service()
   users = users_service.list()

   connection.close()

This snippet fails in the "users = users_service.list()" line, because 
one of the records have a tilde (ó).

It is a but. I think it was introduced recently. Please try to use
version 4.1.3 and check if it works correctly. Open a bug reporting the
results. We will probably need to do something like this to fix it:

  Fix parsing of multi-byte UTF-8 characters
  https://gerrit.ovirt.org/78112



Done [1].

I disagree. Even without reading the post you mention, we already 
noticed that since this version everything is working much faster than 
with prior versions. We have a lot of stuff implemented with Python-SDK 
but on one of them the effect is quite notorious: A script checks VMs' 
permissions and takes decisions based on them. Without pipelining this 
script took about 5 minutes to execute, with pipelining it doesn't take 
more than 15 seconds on a ~1000VMs infrastructure.

It also talks about multiple connection, but don't use

to share cookies, see

[ovirt-users] Cannot move disk to a different DS

[nicolas]

Hi,

We're running oVirt 4.1.1.8. We have a Data Center which had one 
iSCSI-based storage domain (SD). Several machines were created and the 
SD got almost full, so we added another SD. This latter is iSCSI-based 
as well (actually, they're both on the same iSCSI backend), but when 
trying to move a disk to the new one, the "Target" field is empty and I 
have no options to migrate this disk to a different SD (see attached 
snapshot).


The VM that uses this disk is powered off, FWIW.

At the bottom I just get a message saying:

The following disks cannot be moved: windows-server2012R2_Disk1, 
hover over a specific target domain selection for more info.


How can I debug why the new SD is not accessible for moving disks? I 
tried creating a new VM on the new SD and it works fine, it's just the 
migration that doesn't work.

[ovirt-users] News in version 4.1.5.2

[nicolas]

Hi,

We just upgraded to 4.1.5.2 and I see there are 2 news that I'd like to 
ask if they might be changed:


1) Up until now the "User admin@internal logged in." event didn't show 
up, which was a big plus to us because we have many scripts that connect 
to oVirt to do some tasks. As of this version I see this event is back 
:-( Is there a way to disable it so the events list won't get flooded of 
these kind of events?


2) The events list is now ordered top-down. Personally I consider this 
kind of unintuitive and would like to sort events as until now (more 
recent events on top). Is there a way to do this?

​The absence of "User xxx logged in" events was a regression since
4.0, which was fixed in 4.1.2 [1].

Which language are your scripts implemented in? Are you reusing
connections or are you logging in and out for each call?



We're using Python-SDK. On reusing connections, it depends. Some scripts 
do reuse connections (they open a connection and put the main 
implementation inside an endless loop with a sleep() call at the end), 
but others don't because of their nature. I guess we could try to 
reimplement them in a way that just one connection would be opened, but 
currently I'm not sure if all of them can be reimplemented this way.



Thanks

[ovirt-users] Cannot set storage domain on maintenance

[nicolas]

Hi,

We're running ovirt-engine-4.1.5.2-1 and we're trying to set one of the 
storage domains on maintenance in order to remove it, as there's nothing 
left on it besides some templates.


To do so, I open the 'Data Centers' tab, then the 'Storage' subtab, 
select the storage domain and click on 'Maintenance'. When asked for 
confirmation I click OK. After that, this error message is shown:


Error while executing action: Cannot deactivate Storage while there are 
running tasks on this Storage.

-Please wait until tasks will finish and try again.

As far as I know, there are no pending tasks on this storage. The Events 
tab only shows a movement of a disk which has nothing to do with this 
storage domain.


What can I do to solve this?

Unfortunately it didn't work in this case.

I also tried to cleanup entities just in case by running:

# PGPASSWORD=... /usr/share/ovirt-engine/setup/dbutils/unlock_entity.sh 
-t all -u engine

select fn_db_unlock_all();
INSERT 0 1
unlock all  completed successfully.

It seems it clear a hung task but still cannot fix the issue.

Thanks anyway.

It's not the most elegant or guaranteed to fix your issue, but I've

usually cleans up broken and orphaned tasks.

Any running VM's will stay up, you'll just briefly loose access to the
UI while engine-setup restarts the interface.

[ovirt-users] User cannot create VMs having sufficient permissions to do so

[nicolas]

Hi,

We're running ovirt-4.1.6.2-1. We have a user that logs into the user 
portal and tries to create a VM, but a message claiming that "There is 
no Cluster on which you can create a VM. Please check Data Center status 
and Cluster permissions." shows up.


However, this user has permissions on the cluster (both VmCreator and 
DiskProfileUser, and also has a Quota created on the Cluster which 
allows him to create VMs).


When clicking on the 'New VM' button, all we see in the engine.log is:

2017-10-18 10:59:31,825+01 ERROR 
[org.ovirt.engine.core.bll.GetAllLabelsQuery] (default task-103) 
[c23549c6-37a4-48d7-923d-6618e027cdca] Query execution failed due to 
insufficient permissions.


This user has pretty much the same permissions as thousands of users who 
can create VMs, but this one can't.


How can we debug what's happening and how to solve it?

Thanks.
