Hi all,
I reinstalled one of the ovirt-nodes, with ovirt-4.5.4, and after the
reinstallation the agents of the vms connected to this node cannot
communicate with the ovirt-engine.
ovirt-engine 4.5.4
any idea?
VMs work perfectly, but the agent doesn't communicate.
Best regards,

Hi Fernando,
I have also from time to time this issue.
I can see the following in the vdsm.log if the issue occurs:
2022-12-27 10:38:22,473+0100 ERROR (qgapoller/3)
[virt.periodic.Operation] <bound method QemuGuestAgentPoller._poller of

line 797, in _qga_call_get_vcpus
if 'online' in vcpus:
TypeError: argument of type 'NoneType' is not iterable
I had this also in older versions so this is nothing new for me.
Sometimes I can solve it with putting the host in maintenance. But it is
coming back after a while.
Best regards

No for me with 4.5.4-1.el8
Do you see the same error in the vdsm log?
The stacktrace below suggests that the fix is not included there, see:

No this is on none of my 6 hosts.

Hi Arik,
I have checked the installed version of VDSM:
vdsm.x86_64 4.50.3.4-1.el8 @centos-ovirt45
I also refreshed the repos and don't see any update for the VDSM. Looks
like that this version have not been released yet.
Best regards
