Re: [ovirt-users] ovirt question

​inst.stage2 = This specifies the location to fetch ONLY the installer
runtime image; packages will be ignored. ​

I think it is helping to streamline ovirt-node build, as installation part
is untouch OS and we deploy 2nd squash as image of node.

[ovirt-users] oVirt Local Storage Domain Resize

[Samuel Kneppel]

Hello All,

I am fairly new to oVirt and this mailing list, but I am having trouble 
figuring out how to expand my local data storage domain on my oVirt server.

I see that the oVirt system defaults the size of the iso and data domains you 
can create to 50GB.

However, I have a 1TB drive that I would like to fully use for VMs.

Is there a way to expand the current data domain that I have? Or, do I have to 
just keep creating domains when I run out of space on the current storage 
domains?

Thank you,

Samuel Kneppel

Re: [ovirt-users] Emergency shutdown script

[Doug Ingham]

I've plugged this into our monitoring.

When the UPS' are at 50%, it puts the general cluster into global
maintenance & then triggers a shutdown action on all of the VMs in the
cluster's service group via the monitoring agent (you could use an SNMP
trap if you use agentless monitoring). Once all of the VMs are down, it
then continues with the hosts.

At 20%, it does the same with our "core" cluster.

This method means that the HE can be shutdown, and it works whether the HE
is up or not.

For emergencies when the monitoring is offline, I've also hacked up a bash
script which parses the output of vdsClient & uses a loop to send a
shutdown signal to all of the VMs on each host.

I have posted in the past a script which you might be able to use as a
starting point.
I've got a, most of the time, a single server setup using hosted-engine
for development/testing work and shutdown my server when needed.
Recently found out that using 'sanlock client shutdown -f 1 -w 1'  will
allow me to shutdown my server cleanly.
I'll dig up the script when I'm booted into CentOS instead of Windows :-)
Nudge me if I forget to post the script :-)

Joop

Sorry, got pulled onto another project that a coworker needed help on. I

the chance).

Re: [ovirt-users] FreeIPA authentication broken

[Kristian Petersen]

Looks like it can't find the IPA.properties file.  I tried following the
path it is complaining about but there are only files in
/etc/ovirt-engine/extensions.d
on the engine VM.  No subdirectories.  However, that directory appears to
contain the files it is looking for.  Both IPA-authn.properties and
IPA.properties are there as are the internal properties files.  Is there a
config file we can edit to tell it to look in the right place?

Re: [ovirt-users] Problem to upgrade ovirt

[Marcelo Leandro]

Thank you for reply,


"BZ 1515635 [RFE] Drop uuid_generate_v1() internal implementation and use
the implementation from standard PostgreSQL uuid-ossp extension
We have added a requirement for uuid-ossp PostgreSQL extension to be
present in engine database. For databases managed by engine-setup this is
performed automatically, but non-managed databases (usually remote
databases) this needs to be done manually by administrators. "


my database is  managed by engine-setup, so i think that is perfomed
automatically. I know that problem in my database , but I instaled it`s
whith engine-setup com default options.

I try an new instalation in new host and restore backup and when I try
update I had take the same error.


Very thanks!!

You need postgresql 9.5, following the information here should give you 
everything you need:

https://www.ovirt.org/release/4.2.1/

Also look at the information below 'What's New in 4.2.1' it has some 
information on upgrading the uuid generation which requires some manual steps.

Re: [ovirt-users] ovirt question

[Justin Zygmont]

Thanks, but I still don’t understand why there are 2 squash images though.

I was wondering why there has to be 2 node squash images?  A LiveOS/squash.img

When doing a kickstart installation I noticed it uses the Live OS image from 
the inst.stage2= and in the kickstart.cfg it would reference the other node 
image from liveimg --url

Is there any documentation around doing kickstart installs with oVirt?


Thanks,



I too tried some weeks ago (4.2.1 if I remeber correctly) and was confused
I was able to succesfully deploy, with these steps and pxe, also taking 
"inspiration" on what written at this link:
https://github.com/oVirt/ovirt-node-ng/blob/master/docs/book/install.md
note: my pxe server makes also as dhcp server and http server for install

- iso of node-ng-installer
mounted (via loop in my case) under /var/www/html/ovnode42 of pxe server

-under /var/www/html created directory ovnode2_stage2 containing
product.img (6k of file) downloaded here:
http://jenkins.ovirt.org/job/ovirt-node-ng_ovirt-4.2_build-artifacts-el7-x86_64/lastStableBuild/artifact/exported-artifacts/
--> why not included..?
I think in theory one can downoad here also the file updates.img and it should 
update the base version of the iso... TBV (not tested by me)
---> where to get the updates.img? Perhaps inside 
ovirt-node-ng-image-update-x.y.z.rpm?

- inside ovnode2_stage2 created directory LiveOS and inside it created the link
ln -sf /var/www/html/ovnode42/LiveOS/squashfs.img 
/var/www/html/ovnode42_stage2/LiveOS/squashfs.img


- the pxe file

It contains

default pxeboot
timeout 50
label pxeboot
kernel vmlinuz.ovnode42
append initrd=initrd.ovnode42.img 
inst.ks=http://192.168.122.1/ovnode42.ks
 
inst.stage2=http://192.168.122.1/ovnode42_stage2/
 verbose


- kickstart file

in /var/www/html created file ovnode42.ks
it contains

timezone --utc Europe/Rome
firewall --service=ssh

liveimg 
--url=http://192.168.122.1/ovnode42/ovirt-node-ng-image.squashfs.img

# partitioning - nuke and start fresh
zerombr
clearpart --all --initlabel
autopart --type=thinp
bootloader --location=mbr

#reboot

last line left commented to cross-check before reboot

at pxe boot the graphical install comes up and completes the install without 
any prompt
It only asks to reboot as I commented out the line above

verified that after reboot I was able to connect to the server at https on port 
9090 and getting the node dashboard
any validation comment?

Re: [ovirt-users] Help debugging VM import error

[Roy Golan]

I suspect

List guids =
Guid.createGuidListFromString(snap.getMemoryVolume());

where guids is empty because there is not memory volume. which fails this

StorageDomain sd =
getStorageDomainDao().getForStoragePool(guids.get(0),
params.getStoragePoolId());

--log-file=/tmp/aaa.log aaa login-user --user-name nesretep --profile IPA


and share /tmp/aaa.log?



I'm not sure why 'authz' is being ignored but it is certainly why IPA 
authentication isn't working as 'username@authz' is how IPA logins show 
up in oVirt when they do work.  Any ideas where to look next?

[ovirt-users] Help debugging VM import error

[~Stack~]

Greetings,

After my rebuild, I have imported my VM's. Everything went smooth and
all of them came back, except one. One VM gives me the error "General
command validation failure." which isn't helping me when I search for
the problem.

The oVirt engine logs aren't much better at pointing to what the failure
is (posted below).

Can someone help me figure out why this VM isn't importing, please?

Thanks!
~Stack~

[ovirt-users] Emergency shutdown script

[Simon Vincent]

Does anyone have a way of shutting down oVirt automatically in the case of
a power outage?

Ideally I would like a script that can be automatically run when the UPS
reaches a certain level. I had a look at the python SDK but I could only
find functions for shutting down VMs and not hosts. Also I suspect this
wont let me shutdown the hosted engine VM.

Any ideas?

this is not anything we change very often as it then decreases the system’s

You’d have to take a look at vdc_options and play with some of those

 For testing we did not kill any VM but the host. So basically we simulated 
 an instantaneous crash by manually turning the machine off via 
 IPMI-Interface (not via operating system!) and ping the guest(s). What 
 happens then?
 
 2-3 seconds after the we press the host's shutdown button we lose ping 
 contact to the VM(s).
 After another 20s oVirt changes the host's status to "connecting", the 
 VM's status is set to a question mark.
 After ~1:30 the host is flagged to "non responsive”

 After ~2:10 the host's reboot is initiated by oVirt, 5-10s later the guest 
 is back online.
 So, there seems to be one mistake I made in the first mail: The downtime 
 is "only" 2.5min. But still I think this time can be decreased as for some 
 services it is still quite a long time.

Re: [ovirt-users] Hosted Engine won't start, how to debug?

[Martin Sivak]

Hi,

the VM configuration is stored in the engine database and we generate
the vm.conf using the data the engine exports. So you are right, we
overwrite the file.

You might be able to simply edit the VM in the webadmin and enable the
VNC (or Spice) console there. I am not entirely sure if we allow that
atm, but we might.

If that is not allowed, then you will have to edit the DB. The best
way would be to change the vm_static table's origin (should be 6 -
managed hosted engine) field to 3 - ovirt. The webadmin will then
allow you to edit the VM fully. Then change the origin back to 6. All
that for a VM with vm_name = "HostedEngine".

So the fallback procedure for a default install of webadmin (the
database name = engine):

- put hosted engine into global maintenance
- ssh into the engine VM
- sudo -i -u postgres
- psql engine -c "UPDATE vm_static SET origin=3 WHERE vm_name='HostedEngine'"
- edit the VM in webadmin (it should lose its crown status after a
while) and add VNC
- psql engine -c "UPDATE vm_static SET origin=6 WHERE vm_name='HostedEngine'"
- remove global maintenance

All usual disclaimers apply. I recommend backup if it is a production
environment and I can only propose this because I used it repeatedly
during development tests. But production use is on your own risk.

Best regards

Martin Sivak

 You need to be in global maintenance, but I think you already know that.
 Then try updating the vm.conf like you already did and add this line:

 devices={device:vnc,type:graphics,deviceId:f1d0394e-b077-4ea6-99e5-b9b6b8fe073c,address:None}

 Then restart the VM using hosted-engine commands and try the VNC approach 
 again.

[ovirt-users] FreeIPA authentication broken

[Kristian Petersen]

Hey everyone,

I had FreeIPA authentication set up on my oVirt instance and it was working
great.  Then something happened that disconnected my NFS storage and caused
a problem with my hosted-engine.  Once I got it back up and running again,
my FreeIPA authentication was sill a choice for authentication, but it
always rejects my password even though it is correct.  I have tried running
the setup again to no avail.  Nothing shows up in the httpd error log when
the login fails.  The engine.log from ovirt-engine in /var/log shows the
following upon attempting to authenticate with a user from freeIPA:

2018-04-23 08:08:24,384-06 WARN
[org.ovirt.engineextensions.aaa.ldap.Framework] (default task-34) []
Ignoring records from pool: 'authz'
2018-04-23 08:08:24,384-06 ERROR
[org.ovirt.engine.core.sso.servlets.InteractiveAuthServlet] (default
task-34) [] Cannot authenticate user 'nesretep@IPA' connecting from
'UNKNOWN': The username or password is incorrect.

I'm not sure why 'authz' is being ignored but it is certainly why IPA
authentication isn't working as 'username@authz' is how IPA logins show up
in oVirt when they do work.  Any ideas where to look next?

Re: [ovirt-users] Hosted Engine won't start, how to debug?

[Thomas Klute]

Dear Martin,

a follow up question regarding this case:
we managed to get the hosted engine up and running again, but we'd like
to permanently add the missing graphics device to the vm.conf (instead
of starting with the vm-custom.conf in case of trouble).
How do I add this line to the vm.conf config file (it seems to be
overwritten after a few seconds - I suppose it's copied from somewhere?)

Thanks,
Thomas

 Dear Martin,

 thanks for the feedback.
 We already read this and tried it.
 It seems to me that the graphics device was removed from the hosted
 engine by some ovirt release.

 If I try to set a console password I see this message:

 hosted-engine --add-console-password
 Enter password:
 no graphics devices configured

 Furthermore, there is nothing listening on port 5900 after that.
 The HostedEngine qemu process shows a " -display none " as parameter and
 I have no idea where this can be changed.

 I already created a /var/run/ovirt-hosted-engine-ha/vm-custom.conf
 containing:
 display=vnc
 kvmEnable=true

 But nothing changed.
 I also edited the HostedEngine VM config using virsh and added a vnc
 display:
 /usr/bin/virsh -c
 qemu:///system?authfile=/etc/ovirt-hosted-engine/virsh_auth.conf edit
 HostedEngine

 
   
 
 
   >>> heads='1' primary='yes'/>
   >>> function='0x0'/>
 

 But there is still "display none" passed as command line parameter to
 qemu and thus, I suppose, there's no display.

 Any help is appreciated, thanks,
 Thomas

Re: [ovirt-users] Duplicate host_id after deployment via GUI, how is the hosted engine host_id selected?

[Thomas Klute]

Hi Martin,

I fully understand.
The only reason is that it's not only me administering this oVirt setup,
it's a setup for a client that has 2 local administrators.
We are trying to eliminate any configuration that might cause confusion.
When doing a

hosted-engine --vm-status

a list like this is shown:

--== Host 1 status ==--
...
Hostname   : ovirt1.munk.de
Host ID    : 1
...

--== Host 2 status ==--
...
Hostname   : ovirt3.munk.de
Host ID    : 2
...

and so on.
This "Host 2" -> ovirt3 will sooner or later cause confusion and will
lead to administrative actions applied to the wrong hosts.

I'll give it a try and try to align the hosts and ids. I'll backup the
old values in order to be able to roll back the changes if it does not work.

Thanks for your help!!
Best regards,
 Thomas

Re: [ovirt-users] Duplicate host_id after deployment via GUI, how is the hosted engine host_id selected?

[Martin Sivak]

Hi Thomas,

is there a real need to have them aligned? Both SPM ID and Hosted
engine ids are quite hidden and accompanied by hostname where visible.

I understand the urge to have everything neatly organized, but playing
with hosted engine IDs and SPM IDs will bring you nothing but trouble.

Theoretically you could put all hosts to maintenance, hosted engine to
global maintenance, stop the engine service and update the DB and
hosted engine config files. Changing anything when active is a big
NO-NO. And I can't promise stability even if you stop everything
first.

The short version: Please change hosted engine ID to match SPM ID
(/etc/ovirt-hosted-engine/hosted-engine.conf) and ignore the hostname
vs ID mismatch. All other options might cost you..

Best regards

Re: [ovirt-users] Duplicate host_id after deployment via GUI, how is the hosted engine host_id selected?

[Thomas Klute]

Dear Simone,

thanks for the help, I already have noticed, that there is a mismatch
between SPM IDs and the hosts.
>From my knowledge this may be our fault.

 vds_name | vds_spm_id
 oVirt4   |  3
 oVirt2   |  4
 oVirt6   |  6
 oVirt5   |  5
 oVirt1   |  1
 oVirt3   |  2

oVirt3 was re-installed using the node ng image - and was assigned id 2
that was available at that time (taken into account this database query).
It was not available in fact because of the host ovirt2 having the
host_id=2 entry in the configuration on the host and the sanlock having
locked the appropriate space.

I can't remember where this mismatch came from but I assume that some
time ago someone maybe manually changed the entry on oVirt2 host in
order to match with the hostname (oVirtX -> Host id X).
Thus I think it is not a bug at the moment.

But that leads me to the next question:

Is there a manual way to align numbers in the hostnames with the SPM
IDs? (oVirt4 should be spm id 4)

Does this work? Update the database, change the entry in
hosted-engine.conf and then reboot the node?

Thanks & best regards,
Thomas

Thomas,
can you please share the output of
  sudo -u postgres scl enable rh-postgresql95 -- psql -d engine -c "select
vds_id, vds_name, vds_spm_id from vds"
executed on the engine VM

and the content of /var/log/ovirt-engine/host-deploy (still from the engine

why not? You are the one selecting teh VM’s CPU…why not use Nehalem too?

running VMs will change on their power cycle. Unless you used per-VM CPU Type

if all your hosts support it

not sure I understand the question. Normally you can use any CPU as long as it 
is supported by all hosts in the cluster. You can use per-VM override to bypass 
that, but that’s usually not a good idea

Re: [ovirt-users] Duplicate host_id after deployment via GUI, how is the hosted engine host_id selected?

[Martin Sivak]

Hello,

the ID should be coming from the SPM ID of the host as assigned by the
engine and duplicates should not be happening indeed.

Can you please tell us what version of engine you have and how was
first hosted engine node deployed? We recently changed the default
deployment method (4.2.2 in fact) and we would like to know whether
this might be related to that change or not.

Simone, do you know how to debug this? Are there logs we could use to
check the behavior? The host-deploy logs maybe?

Best regards

Re: [ovirt-users] problem with ovirt-container-engine

[Michael Mortensen (MCMR)]

That's a very old project - I haven't tried it myself, but I suspect that the 
project has died. Can anyone confirm?
Setting up an engine on a machine is very easy though, so if you have one 
spare, it should be straight forward.

[ovirt-users] Duplicate host_id after deployment via GUI, how is the hosted engine host_id selected?

[Thomas Klute]

Dear oVirt Users,

we installed a third ovirt node using the ovirt node ng image (4.2.2),
and added that node using the web interface of the hosted engine:

Compute->Hosts->New - including the Hosted engine option "Choose hosted
engine deployment action" set to "Deploy"

After that we found out, that on the new node the host_id entry was
causing problems. In

/etc/ovirt-hosted-engine/hosted-engine.conf

we found the entry

...
host_id=2
...

But that host id already exists and was alive during deployment process.
So my questions are:

  * How is the host id chosen (when adding a new host via GUI)?
  * Is there an option to preselect the host id in the GUI for a new node?
  * How can we prevent further duplicate host ids?

Thanks and best regards,
Thomas

OK, now i found https://bugzilla.redhat.com/show_bug.cgi?id=1519301 
which describes the problem, but doesn't give a solution...


it sounds like removing the "optional in 4.1.9" package 
ovirt-ansible-roles before the upgrade would prevent the error, but i 
would like to finish the upgrade in my test environment where i didn't 
do this. how can i do that?




i finally resolved the situation by force removing (rpm -e --nodeps) the 
ovirt-ansible-* packages, after that engine-setup finishes ok, in the 
end i execute "yum install ovirt-ansible-roles". this _seems_ to work...


thx matthias

OK, now i found https://bugzilla.redhat.com/show_bug.cgi?id=1519301 
which describes the problem, but doesn't give a solution...


it sounds like removing the "optional in 4.1.9" package 
ovirt-ansible-roles before the upgrade would prevent the error, but i 
would like to finish the upgrade in my test environment where i didn't 
do this. how can i do that?


thx

Re: [ovirt-users] create VM failed

[Michal Skrivanek]

looks like some host misconfiguration. Make sure you deploy a host correctly - 
CentOS 7.4//RHEL 7.5, without any system modification...

Re: [ovirt-users] Cannot update Node 4.2 to 4.2.2

[Pavol Brilla]

can you try to run:
# nodectl info

if you have results back you are on ovirt-node

if -bash: nodectl: command not found - most probably you are on CentOS with
VDSM

Re: [ovirt-users] Decrease downtime for HA

[Daniel Menzel]

Hi Michal,

in your last mail you wrote, that the values can be turned down - how 
can this be done?

Hi Michal,




Hi Daniel,
adding Martin to review fencing behavior


(sorry for misspelling your name in my first mail).




that’s not the reason I’m replying late!:-))


The settings for the VMs are the following (oVirt 4.2):

 1. HA checkbox enabled of course
 2. "Target Storage Domain for VM Lease" -> left empty



if you need faster reactions then try to use VM Leases as well, it 
won’t make a difference in this case but will help in case of network 
issues. E.g. if you use iSCSI and the storage connection breaks while 
host connection still works it would restart the VM in about 80s; 
otherwise it would take >5 mins.


 3. "Resume Behavior" -> AUTO_RESUME
 4. Priority for Migration -> High
 5. "Watchdog Model" -> No-Watchdog

For testing we did not kill any VM but the host. So basically we 
simulated an instantaneous crash by manually turning the machine off 
via IPMI-Interface (not via operating system!) and ping the 
guest(s). What happens then?


 1. 2-3 seconds after the we press the host's shutdown button we
lose ping contact to the VM(s).
 2. After another 20s oVirt changes the host's status to
"connecting", the VM's status is set to a question mark.
 3. After ~1:30 the host is flagged to "non responsive”



that sounds about right. Now fencing action should have been 
initiated, if you can share the engine logs we can confirm that. IIRC 
we first try soft fencing - try to ssh to that host, that might take 
some time to time out I guess. Martin?


3.


 4. After ~2:10 the host's reboot is initiated by oVirt, 5-10s later
the guest is back online.

So, there seems to be one mistake I made in the first mail: The 
downtime is "only" 2.5min. But still I think this time can be 
decreased as for some services it is still quite a long time.





these values can be tuned down, but then you may be more susceptible 
to fencing power cycling a host in case of shorter network outages. It 
may be ok…depending on your requirements.

Daniel

Hi Michael,
thanks for your mail. Sorry, I forgot to write that. Yes, we have power 
management and fencing enabled on all hosts. We also tested this and found out 
that it works perfectly. So this cannot be the reason I guess.

Hi Daniel,
ok, then it’s worth looking into details. Can you describe in more detail what 
happens? What exact settings you’re using for such VM? Are you killing the HE 
VM or other VMs or both? Would be good to narrow it down a bit and then review 
the exact flow

Thanks,
michal

Hello,

we're successfully using a setup with 4 Nodes and a replicated Gluster for 
storage. The engine is self hosted. What we're dealing with at the moment is 
the high availability: If a node fails (for example simulated by a forced power 
loss) the engine comes back up online withing ~2min. But guests (having the HA 
option enabled) come back online only after a very long grace time of ~5min. As 
we have a reliable network (40 GbE) and reliable servers I think that the 
default grace times are way too high for us - is there any possibility to 
change those values?

And do you have Power Management(iLO, iDRAC,etc) configured for your hosts? 
Otherwise we have to resort to relatively long timeouts to make sure the host 
is really dead
Thanks,
michal

Thanks in advance!

Hi Stack,

Indeed this is a bug in the engine. We have opened a case [1] and are
working to fix it on 4.2 ASAP

Re: [ovirt-users] oVirt permissions

[Roy Golan]

We don't limit admin roles from querying assets, so the simple answer is no.
