Import an exported VM using Ansible
by paolo＠airaldi.it
Hello everybody!
I'm trying to automate a copy of a VM from one Datacenter to another using an Ansible.playbook.
I'm able to:
- Create a snapshot of the source VM
- create a clone from the snapshot
- remove the snapshot
- attach an Export Domain
- export the clone to the Export Domain
- remove the clone
- detach the Export domain from the source Datacenter and attach to the destination.
Unfortunately I cannot find a module to:
- import the VM from the Export Domain
- delete the VM image from the Export Domain.
Any hint on how to do that?
Thanks in advance. Cheers.
Paolo
PS: if someone is interested I can share the playbook.

did 4.3.9 reset bug https://bugzilla.redhat.com/show_bug.cgi?id=1590266
by kelley bryan
I am experiencing the error message in the ovirt-hosted-engine-setup-ansible-create_target_vm log
{2020-05-06 14:15:30,024-0500 ERROR ansible failed {'status': 'FAILED', 'ansible_type': 'task', 'ansible_task': u"Fail if Engine IP is different from engine's he_fqdn resolved IP", 'ansible_result': u'type: <type \'dict\'>\nstr: {\'msg\': u"Engine VM IP address is while the engine\'s he_fqdn ovirt1-engine.kelleykars.org resolves to 192.168.122.2.

The bug 1590266 says it should report the engine VM IP address xxx.xxx.xxx.xxx while the Engines he_fqdn is xxxxxxxxx
I need to see what it thins is wrong as both dig fqdn engine name and dig -x ip return the correct information.
Now this bug looks like it may play but I don't see the failed rediness check in the this log https://access.redhat.com/solutions/4462431
or is it because the vm fails or dies or ???

How to renew vmconsole-proxy* certificates
by capelle＠labri.fr
Hi,
Since a few weeks, we are not able to connect to the vmconsole proxy:
$ ssh -t -p 2222 ovirt-vmconsole@ovirt
ovirt-vmconsole@ovirt: Permission denied (publickey).
Last successful login record: Mar 29 11:31:32
First login failure record: Mar 31 17:28:51
We tracked the issue to the following log in /var/log/ovirt-engine/engine.log:
ERROR [org.ovirt.engine.core.services.VMConsoleProxyServlet] (default task-11) [] Error validating ticket: : sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target
Indeed, certificate /etc/pki/ovirt-engine/certs/vmconsole-proxy-helper.cer and others did expire:
--
# grep 'Not After' /etc/pki/ovirt-engine/certs/vmconsole-proxy-*
/etc/pki/ovirt-engine/certs/vmconsole-proxy-helper.cer: Not After : Mar 31 13:18:44 2021 GMT

/etc/pki/ovirt-engine/certs/vmconsole-proxy-user.cer: Not After : Mar 31 13:18:44 2021 GMT

But we did not manage to found how to renew them. Any advice ?

Snapshot and disk size allocation
by jorgevisentini＠gmail.com
Hello everyone.
I would like to know how disk size and snapshot allocation works, because every time I create a new snapshot, it increases 1 GB in the VM's disk size, and when I remove the snap, that space is not returned to Domain Storage.
I'm using the oVirt 4.3.10
How do I reprovision the VM disk?
Thank you all.

UEFI Guest can only be started on UEFI host (4.4)
by nroach44＠nroach44.id.au
Hi All,
A problem I've just "dealt with" over the past months is that the two UEFI VMs I have installed (One Windows 10, one RHEL8) will only start on the oVirt Node (4.4.x, still an issue on 4.4.8) hosts that have been installed using UEFI.
In the case of both guests, they will "start" but get stuck on a small 640x480-ish black screen, with no CPU or disk activity. It looks as if the VM has been started with "Start paused" enabled, but the VM is not paused. I've noticed that this matches the normal startup of the guest, although it only spends a second or two like that before TianoCore takes over.
Occasionally, I'm able to migrate the VM to a BIOS host. When it fails, the following is seen on the /sending/ host:

Any suggestions?

HA VM and vm leases usage with site failure
by Gianluca Cecchi
Hello,
supposing latest 4.4.7 environment installed with an external engine and
two hosts, one in one site and one in another site.
For storage I have one FC storage domain.
I try to simulate a sort of "site failure scenario" to see what kind of HA
I should expect.
The 2 hosts have power mgmt configured through fence_ipmilan.
I have 2 VMs, one configured as HA with lease on storage (Resume Behavior:
kill) and one not marked as HA.
Initially host1 is SPM and it is the host that runs the two VMs.
Fencing of host1 from host2 initially works ok. I can test also from
command line:
# fence_ipmilan -a 10.10.193.152 -P -l my_fence_user -A password -L
operator -S /usr/local/bin/pwd.sh -o status
Status: ON
On host2 I then prevent reaching host1 iDRAC:
firewall-cmd --direct --add-rule ipv4 filter OUTPUT 0 -d 10.10.193.152 -p
udp --dport 623 -j DROP
firewall-cmd --direct --add-rule ipv4 filter OUTPUT 1 -j ACCEPT
so that:
# fence_ipmilan -a 10.10.193.152 -P -l my_fence_user -A password -L
operator -S /usr/local/bin/pwd.sh -o status
2021-08-05 15:06:07,254 ERROR: Failed: Unable to obtain correct plug status
or plug is not available
On host1 I generate panic:
# date ; echo 1 > /proc/sys/kernel/sysrq ; echo c > /proc/sysrq-trigger
Thu Aug 5 15:06:24 CEST 2021
host1 correctly completes its crash dump (kdump integration is enabled) and
reboots, but I stop it at grub prompt so that host1 is unreachable from
host2 point of view and also power fencing not determined
At this point I thought that VM lease functionality would have come in
place and host2 would be able to re-start the HA VM, as it is able to see
that the lease is not taken from the other host and so it can acquire the
lock itself....
Instead it goes through the attempt to power fence loop
I wait about 25 minutes without any effect but continuous attempts.
After 2 minutes host2 correctly becomes SPM and VMs are marked as unknown
At a certain point after the failures in power fencing host1, I see the
event:
Failed to power fence host host1. Please check the host status and it's
power management settings, and then manually reboot it and click "Confirm
Host Has Been Rebooted"
If I select host and choose "Confirm Host Has Been Rebooted", then the two
VMs are marked as down and the HA one is correctly booted by host2.
But this requires my manual intervention.
Is the behavior above the expected one or the use of VM leases should have
allowed host2 to bypass fencing inability and start the HA VM with lease?
Otherwise I don't understand the reason to have the lease itself at all....
Thanks,
Gianluca

Re: About the vm memory limit
by Tommy Sway
transparent huge pages are not used on vm and physical host.
But, can I enable hugepage memory on virtual machines but not on a physical machine?
For database running on vm, and it needs to config hugepage.

Subject: Re: [ovirt-users] About the vm memory limit
It depends on the numa configuration of the host.
If you have 256G per CPU, it's best to stay into that range.
Also, consider disabling transparent huge pages on the host & VM.
Since 4.4 Regular Huge Pages (do not confuse them with THP) can be used on the Hypervisors, while on 4.3 there were some issues but I can't provode any details.

As long as there is memory on the physical machine, the more virtual machines the better?
In our usage scenario, there are many virtual machines with databases, and their memory varies greatly.
For some virtual machines, 4G memory is enough, while for some virtual machines, 64GB memory is needed.
I want to know what is the best use of memory for a virtual machine, since the virtual machine is just a QEMU emulation process on a physical machine, and I worry that it is not using as much memory as a physical machine. Understand this so that we can develop guidelines for optimal memory usage scenarios for virtual machines.
Thank you!
