Hi Guys

Any help will be appreciated, my VMs on my KVM hyp (Almalinux 8) randomly freezes. It does not happen with all of them at once but at least once a week one VM randomly freezes. It does not respond to console nor can I check /var/log/libvirt/qemu/i-2-118-VM.log in the KVM there is nothing. I also check cloudstack and agent logs and I am not seeing anything obvious. I then investigate the VM too. There too I see nothing journalctl only has the latest boot information once the VM is forced reboot via Cloudstack UI, which is the only way I can bring it up again.

What's also weird, I have Ha enabled for all my VMs it works when I for example shutdown the VM inside the VM then Ha bring it up again. But in this case, Ha doesn't seem to detect the VM is in a "frozen" state to reboot it.

If anyone has had a similar experience before, I will appreciate any advice to help troubleshoot this, please.
