Re: [External] : Re: about the hugepage setting of the KVM server
by Tommy Sway
I use the ovirt-node, and I configured HUGEPAGE on the VM, and does not
configure the HUGEPAGE on the KVM host.
The THP I don't configure anything about it, and after configure the
HUGEPAGE on the vm, there is no report.
I don't know which method is the best.

Hi Tommy,
I have no simple answer to your question since I did not need this before,
but some questions may help us understand how it is currently working.
1st- Are you using an ovirt-node or an OS+vdsm as a hypervisor?
2nd- Did you enabled huge pages on the VM OS?
3rd- Did you check on the hypervisor OS if transparent hugepages (THP) is
enabled? And if, after enabling/configuring hugepages in the VM, it is
reporting hugepages are in use in the host?

Subject: [ovirt-users] about the hugepage setting of the KVM server
Hi:
I am running virtual machines on the KVM servers of oVirt env. The virtual
machine is running database, which needs to set the memory huge page on the
OPERATING system of the virtual machine.
If I need to set the huge page on the VIRTUAL machine, do I also need to set
huge page on the KVM physical machine? Or just on the virtual machine?
What best practices do you recommend?
Thank you very much!

Unable to export VM from data storage domain.
by Diggy Mc
I'm running oVirt 4.4.4 with two data storage domains. One domain is where the production VMs run. The second domain is where I make backup copies of the VMs in the event of problems with the main production VMs. I make backups using the export option from the GUI's dropdown list.
I just now tried to "restore" a backup copy via the export function and get an error. In fact, I get errors trying to export (import to my original data domain) any of the VMs that were exported to my backup data domain. My backup domain is a DATA domain and not an EXPORT domain.
The exact error is:
Export VM Failed
[Cannot add VM. Cannot find a disk profile defined on storage domain 246c69e9-6f16-489f-8022-8613f6c1c22a.]
Is this a bug or am I doing something wrong? Help is needed urgently. In advance, thank you.

Import OVA problem

I have tried exporting 4 VMs (2 centos and 2 Windows) to an nfs mount (export OVA) and importing from ova and I can't see all the files.
Here are the files in the directory

The only file I see in virtual machine on source is linuxtest.ova and linux2.ova. Do you know why ?

Re: How to re-import a VM with an invalid timezone?
by Saif Abu Saleh
Hi,
Can you please provide what time-zone the VM you are trying to Import has?
if you are trying to import from the OVA you can get the time-zone by going
to the host location where the exported OVA exists,
open it and check what is the value of the <TimeZone> tag
Thanks,
Saif

Crash Debugging VDSM Hook
by Jean-Louis Dupond
Hi All,
While debugging some Qemu 6 issue I was requested to remove the
error_policy from the libvirt xml.
See https://bugzilla.redhat.com/show_bug.cgi?id=1999051#c12
Now to have this working I just wrote some small python hook for VDSM
which adjusts the XML before startup.
Just added the file in /usr/libexec/vdsm/hooks/before_vm_start:
# cat 40_crashtest
#!/usr/libexec/platform-python
import os
import hooking
class CrashTestHook(object):
def __init__(self):
super(CrashTestHook, self).__init__()
self.config = {}
self.domxml = hooking.read_domxml()
def save(self):
hooking.write_domxml(self.domxml)
def set_error_policy(self):
drivers = self.domxml.getElementsByTagName('driver')
for driver in drivers:
policy = driver.getAttribute('error_policy')
if policy == 'stop':
driver.removeAttribute('error_policy')
def main(self):
self.set_error_policy()
self.save()
if __name__ == "__main__":
CrashTestHook().main()
# vim: expandtab tabstop=4 shiftwidth=4
Might be usefull if somebody else needs the same thing :)

oVirt Hosted Engine Offline Deployment
by Andrew Lamarra
Hi there. I'm trying to get oVirt up & running on a server in a network that has no access to the Internet. We do host mirrors of CentOS 7 & 8 repos (no Stream). I first tried the latest version of oVirt 4.4, however, I ran into an issue when trying to do the Hosted Engine deployment. The command I used was "hosted-engine --deploy --ansible-extra-vars=he_offline_deployment=true". But at some point, I get the following error:
[ INFO ] DNF Errors during downloading metadata for repository 'ovirt-4.4-centos-ceph-pacific':
- Status code: 404 for http://mirror.centos.org/centos/8-stream/storage/x86_64/ceph-pacific/repo...
[ ERROR ] DNF Failed to download metadata for repo 'ovirt-4.4-centos-ceph-pacific': Cannot download repomd.xml: Cannot download repodata/repomd.xml: All mirrors were tried
Seems like it's still trying to download something from the CentOS 8 Stream repo. So I figured that since we have the CentOS 7 repos hosted, I'll try oVirt v4.3. However, I don't see an option to do an "offline deployment" with this version. It says the "--ansible-extra-vars" option is invalid. I tried doing a regular deployment but it tries downloading from the oVirt repo:
[ INFO ] TASK [ovirt.hosted_enging_setup : Install ovirt-engine-appliance rpm]
[ ERROR ] fatal: [localhost]: FAILED! => ["attempts": 10, "changed": false, "msg": "Failure talking to yum: cannot retrieve metalink for repository: ovirt-4.3-epel/x86_64. Please verify its path and try again"}
I can bring over a mirror of the ovirt-4.3 repo. I also see that there's some other repos in the "ovirt-4.3-dependencies.repo" file. Are those required for deploying the hosted engine VM as well? Or does anyone know if there's a way to do this deployment completely offline?
Thank you for your time.

testing 4.3.10 to 4.4.7 upgrade SHE
by Gianluca Cecchi
Hello,
I'm testing what in object in a test env.
For this I downloaded the async 1 iso of the node, released on 14/07:
https://resources.ovirt.org/pub/ovirt-4.4/iso/ovirt-node-ng-installer/4.4...
and downloaded to manually install and avoid 4.4.8 appliance:
https://resources.ovirt.org/pub/ovirt-4.4/rpm/el8/x86_64/ovirt-engine-app...
released on 05/07
BTW: what is the difference with
https://resources.ovirt.org/pub/ovirt-4.4/rpm/el8/x86_64/ovirt-engine-app...
as both the rpm in changelog contains at top:
* Mon Jul 05 2021 Sandro Bonazzola <sbonazzo(a)redhat.com> - 4.4
- oVirt 4.4.7 GA appliance
I'm in the phase where I have installed the iso, manually installed the
4.4.7 appliance rpm and then:
tmux
hosted-engine --deploy --restore-from-file=backup.bck
It seems I'm stuck at step:

I suspect the error related to the gpg key import....
any insights?
Does my strategy to keep 4.4.7 on upgrade from 4.3.10 apply, or anyway the
appliance will upgrade anyway to 4.4.8 during the setup?
thanks,
