Or show the top 5 VMs and below it, the top 5 hosts. This way the text
isn't cut:

Most utilized VMs:
abc-vm 107%
def-vm 105%
this-and-that-vm 44%

Most utilized hosts:
this-host 27%

Look at the vdsm.log for events which libvirt emits and the actions that
vdsm takes on them. One of the actions would be to unpause the VM AFAIR. If
you didn't see this then QEMU/libvirt failed to propagatate the new state
change or it might be deeper down the stack. If there are events there then
share the vdsm logs.

[ovirt-users] Maintenance on the Mailing-Lists

[Duck]

Quack,

I'm working in the OSAS team and arrived recently. Yoroshiku onegai shimasu.

With the oVirt infra team we're working on the Mailing-Lists. In the
past there was SPF problems leading to mails being classified as SPAM,
especially affecting GMail users. A workaround was made, but it's not
nice and history of this time was mostly lost.

I'm then going to make some changes which I believe would work, but just
in case I'm sending this message to the main Mailing-Lists so you can
check your SPAM box and break my head on #ovirt@freenode if it fails :-).

Right.

After engine-setup finishes, you should 'yum update' to update the rest.

And BTW, this specific issue about tools-backup was fixed in [1]. So a
future 'yum update' should not emit this error - although the update
sequence is still the same - add repos, update setup packages, engine-setup,
update the rest.

[ovirt-users] On 3.6.6, tried doing a live VM storage migration... didn't work

[Christopher Cox]

In our old 3.4 ovirt, I know I've migrated storage on live VMs and everything 
seemed to work.


However on 3.6.6, I tried this and I saw the warning about moving storage on a 
live VM (it wasn't doing much of anything) and I went ahead and migrated the 
storage from one storage domain to another.   But when it was through, even 
though the VM was still alive, when I tried to write to a virtual disk that was 
part of the move, it paused the VM saying there wasn't enough storage.


I could unpause the VM, but in a few seconds, with things writing to the virtual 
disk, again it was paused with the same out of space message.  Vdsm logs showed 
the enospc return code... so it made sense, it's just that the VM shows plenty 
of storage there.  Once I rebooted the VM, everything went back to normal.


So is moving storage for a live VM not supported?  I guess we got lucky in our 
3.4 system (?)

Yeah. Hm, dunno why it didn't work, perhaps the config is not set up correctly. 
I thought redeploy would fix it but I don't really know the deployment code so 
maybe I'm wrong

 yeah, I think it didn’t happen. I though we do relabelling as part of 
 deploy
 How about running "restorecon -r” now?

I have seen this doc.

It updates a few components and what about the others ? The readme talk about 
running engine-setup, but not that it will updates other packages. I thought 
that ovirt-engine is for engine setup, not upgrading.

Re: [ovirt-users] SELinux and oVirt

[Cam Mac]

Hi Michal,

Ran restorecon -r on '/' (and restarted vdsmd and other services): it is
still getting selinux errors. I'd like to keep selinux running, especially
as it is officially supported (and works on the other node), so I guess the
best option is to reinstall the OS and then install ovirt again perhaps.

Thanks,

Campbell

 for engine..well, VM security is not related to that, those are running

 irrelevant what SELinux state it’s in
 I’m not sure if relabeling with restorecon is not enough (it sould work

It shouldn't hurt on /, it should only help:)
And if it complains e.g. on attached nfs, the i suppose you need to run it

yeah, I think it didn’t happen. I though we do relabelling as part of deploy

I guess the two lists in portrait mode are truncated all the time, it would 
probably make more sense to show only one column and switch hosts/vms via

Any ideas? How can I debug why the engine is not doing any attempt to

Forgot to mention versions:

engine is Centos 6 ovirt-engine-3.6.6.2-1.el6.noarch, 
ovirt-optimizer-ui-0.9.1-2.el6.noarch

I think I figured this out.
The connection to optimizer is being done by client's browser and not 
the engine...

I used a private network which was not accessible from the browser.

Re: [ovirt-users] SELinux and oVirt

[Cam Mac]

Hi Michal,

I chose the 'reinstall node' option from the GUI menu, which appeared to go
ok, however, I still cannot create or migrate a VM on that node. I can see
selinux 'denied' messages relating to qemu-kvm, e.g.:

type=AVC msg=audit(1464189232.136:251): avc:  denied  { read } for
 pid=4019 comm="qemu-kvm" name="65ab-b33a-483a-af46-76f7305e2ae5"
dev="sda2" ino=35401 scontext=system_
u:system_r:svirt_t:s0:c720,c927 tcontext=system_u:object_r:unlabeled_t:s0
tclass=lnk_file

There are a number of errors in the vdsm log but I assume that relates to
selinux blocking it. So perhaps I need to remove all the ovirt packages
manually, or perhaps re-install the OS as well? I guess either of those
options involves complications with certificates and WWIDs for the attached
SAN.

Or could I somehow generate selinux labels?

These nodes + engine are not yet production, though I'd prefer to fix than
restart entirely from scratch.

Thanks for any help.

regards,

Campbell

Yes, these are the logs when using the command you gave me, using the search

You use 389 with SSL? I guess you wrongly specified it.

But, if you want to use SSL and you have it on 636, then you should 
create new SRV dns

records for example: _ldaps._tcp.university.mydomain.com ... 636

and then change:

 pool.default.serverset.srvrecord.service=ldaps

But I guess you wanted to use startTLS with 389, which you can enable by 
adding:


 pool.default.ssl.startTLS=true

and remove line:

 pool.default.ssl.enable=true

Does it solve your issue?




By the way, if I didn't rename my .profile and auth* files from my LDAP 
configuration, I had the LDAP namespace suggested by the web interface in my AD 
domain when trying to >>perform a search. Is that a bug ?



Not sure I understand. The name of the profile could be whatever, so it
doesn't matter what is the name.


I meant I had to disable the LDAP (openLDAP) profile, renaming the file with 
.save so ovirt doesn't detect them. If both profiles are activated, ovirt-web 
interface propose me the DN of the LDAP into AD (in namespace field)... Is that 
a bug or normal behavior ?



Hmm, that's strange, because only files with *.properties suffix should 
be detected and used. So yes please open bz that also other suffixes are 
loaded.


Btw: you can add at the begging of each file (authz and authn) this line 
to disable it:


 ovirt.engine.extension.enabled = false

Re: [ovirt-users] How to setup host network to link ovirtmgmt with eth0 automatically?

[Ondřej Svoboda]

Kai,

The symptoms after removal of vdsm-hook-ovs look just like the ovirtmgmt 
bridged network was not created. The log to look in would be 
supervdsm.log, but it looks like yours has been rotated after supervdsmd 
was restarted (the warning is benign). Can you dig out "supervdsm.log.1"?


OVS started to be supported by the hook initially (this was the first 
attempt at supporting OVS). Currently, proper OVS support is in 
development and should appear in 4.0 as a tech-preview.


Thanks,
Ondra (osvob...@redhat.com)

Hi again, (correcting myself a bit)

are using the Open vSwitch hook intentionally? If not, you can
|yum remove vdsm-hook-ovs| for a while. What is your exact VDSM
version?


My VDSM version is 4.17.24 and ovirt-engine is 3.6.4. When after 
remove ovs hooks, it still fails with:


 "Host node3 does not comply with the cluster Default networks, the 
following networks are missing on host: 'ovirtmgmt'".


I checked vdsm.log it seems no erros there. And in supervdsm.log, it 
shows warnings:

What should I check next? Thanks.

I uploaded vdsm.log to:

https://gist.github.com/parr0tr1ver/1e38171b5d12cf77321101530276d368

and supervdsm.log:

https://gist.github.com/parr0tr1ver/97805698a485f1cd49ded2b095297531


Also, can you give a little more context from your vdsm.log, and
also from supervdsm.log? I think the vdsm.log failure is only
related to stats reporting, and is not the root problem.

If you don't have any confidential information in the logs (or you
can remove it), I suggest that you open a bug on product=vdsm at
https://bugzilla.redhat.com/ Have no fear about naming the bug, it
can be renamed if necessary.



I find there is a bug on 
https://bugzilla.redhat.com/show_bug.cgi?id=1234867. The "Target 
Milestone" to "support ovs via vdsm hook" is ovirt-3.6.7. Does that 
mean ovs does not work actually in previous versions?


Thanks a lot.

[ovirt-users] moVirt 1.4 RC1 (Android client for oVirt)

[Tomas Jelinek]

Hey All,

the first RC of moVirt 1.4 has been released! 

It can be downloaded only using direct link[1] - the play store will be 
upgraded after considered stable.

The most important feature of this release was to enhance the dashboard so it 
will look similar to the one coming to oVirt 4.0.
Screenshot attached.

Other changes:
- Added new dashboard functionality (virtual/physical consumption, clickable 
cpu/memory consumption)
- Better UI (dashboard, adding/editing triggers)
- Better sorting in lists
- Memory units are now displayed correctly
- Fixed crashing bugs when looking at hosted engine

Would you like to help/contribute?
Sure, for example you can:
- give feedback on the new dashboard (the one from the attachment)
- download RC [1], test it and report bugs
- patches are also welcome :)

have a nice day,
Tomas

Hi,

I have a peculiar problem with oVirt 3.6. Any VM connected to ovrtmgmt 
is working absolutely fine, bu the VMs (Windows Guests) in different 
VLANs say 10, 32, 34, 40, 48 & 69 are not able to even ping their 
respective gateways. In other words, network packets are not coming out 
of the VMs at all.


1. Our infrastructure consists of Lenovo Flex Chassis with 3 Lenovo x240 
Compute nodes. All nodes are up and running and VMs are also created and 
guest OS installed.

2. Chassis switch has a trunk port that carries all VLAN traffic.
3. I have created logical networks and added VLAN tags (10, 32, 24, 40, 
48 & 69).
4. I have attached the vNIC to each host and assigned static IP in 
respective VLANs. For example in VLAN 32, the vNIC is assigned with 
172.20.101.70, subnet: 255.255.255.192, Gateway: 172.20.101.65
5. VMs are mapped with respective vNIC and assigned IPs in respective 
VLAN. For Example, VM in VLAN 32 has 172.20.101.79 as IP, 
255.255.255.192 as subnet and 172.20.101.65 as gateway.


Now, VM is able to ping vNIC in VLAN 32, but neither VM is able to ping 
the gateway nor hosts are able to ping vNIC or the VM.


We even attempted with replacing a trunk port with access port, but same 
issue continues.


What could have gone wrong? Any thing missing on oVirt configuration?

A quick help is highly appreciated.

Or run this command and send output of file 'login.log':

Any ideas ?




By the way, if I didn't rename my .profile and auth* files from my LDAP 
configuration, I had the LDAP namespace suggested by the web interface in my AD

Not sure I understand. The name of the profile could be whatever, so it 
doesn't matter what is the name.

Re: [ovirt-users] add user permissions to a template

[Ondra Machacek]

If I understand correctly, then 'copy template permissions' is feature 
you are looking for.


When you are creating vm from the template, click on 'Show advanced 
options' and then you can see 'copy template permissions' checkbox, 
which will do the work for you.

[ovirt-users] Struggling to get the network work

[Anantha Raghava]

Hi,

I have a peculiar problem with oVirt 3.6. Any VM connected to ovrtmgmt 
is working absolutely fine, bu the VMs (Windows Guests) in different 
VLANs say 10, 32, 34, 40, 48 & 69 are not able to even ping their 
respective gateways. In other words, network packets are not coming out 
of the VMs at all.


1. Our infrastructure consists of Lenovo Flex Chassis with 3 Lenovo x240 
Compute nodes. All nodes are up and running and VMs are also created and 
guest OS installed.

2. Chassis switch has a trunk port that carries all VLAN traffic.
3. I have created logical networks and added VLAN tags (10, 32, 24, 40, 
48 & 69).
4. I have attached the vNIC to each host and assigned static IP in 
respective VLANs. For example in VLAN 32, the vNIC is assigned with 
172.20.101.70, subnet: 255.255.255.192, Gateway: 172.20.101.65
5. VMs are mapped with respective vNIC and assigned IPs in respective 
VLAN. For Example, VM in VLAN 32 has 172.20.101.79 as IP, 
255.255.255.192 as subnet and 172.20.101.65 as gateway.


Now, VM is able to ping vNIC in VLAN 32, but neither VM is able to ping 
the gateway nor hosts are able to ping vNIC or the VM.


We even attempted with replacing a trunk port with access port, but same 
issue continues.


What could have gone wrong? Any thing missing on oVirt configuration?

A quick help is highly appreciated.

Bonding mode 2 also tested


On the hosts, try setting LRO off on the members of your bond, see if it 
makes a difference


eg,

ethtool -K ens3f0 lro off
ethtool -K ens3f1 lro off

[ovirt-users] add user permissions to a template

[Nathanaël Blanchet]

Hi all,

I don't want to add permission to manage a template, but I want to set 
permission to this template so as to each new vm created from this 
template inherits of the same permissions.

Many thanks.

[ovirt-users] Ovirt Engine - Wait For Launch

[Maton, Brett]

I did a yum update on one of my Ovirt Hosts a few days ago.
All of the VM's on that host have been shown in the web UI with a status of
'Wait For Launch'.

The VM's all appear to still be up and running but I can't manage/migrate
them.

Is there anything I can do to clear this issue ?

Regards,
Brett
