Unknown Power State after libvirtd restart

Support
1

Hi,
I'm starting using Foreman to provision and manage hosts on a separate KVM
machine, and it happens that if I restart libvirtd, even while no host is
active, then Foreman "loses the connection" with libvirt and reports the
hosts as being in "Unknown Power State".
I need to restart Foreman to fix this, and then the first connection to
Foreman's web GUI after the restart is slow.
This is a bit annoying.

Is it normal behaviour?
Can it be prevented somehow?

Thanks.
Marco

I'd try to close all browsers before restarting libvirtd, it might force
the connection to be opened while restarting libvirtd. Also, libvirt
daemon is changing firewall configuration when (re)starting, check that
too.

Well… restarting the browser could be even more annoying than restarting
Foreman, actually ;).

Yes I know, but libvirt's firewall rules were already in place before the
restart of the daemon.
Moreover, if it was a firewall problem on the KVM host then the workaround
by restarting Foreman on the other machine wouldn't make much sense IMHO.

Thank you.

Yeah, I meant closing all Foreman-related tabs.

Not sure what is causing this, sorry.

Yeah, I meant closing all Foreman-related tabs.

Well, this actually did not work… not in Chrome on OSX, at least.
After closing the only Foreman tab I had open, I opened a new tab, typed
the Foreman server address, was automatically logged in, and the host was
still in "Unknown Power State".
I also tried logging out before closing the tab, and then logging in again
in the new tab, but the result was the same.

Thanks.

Looking at the code, it should handle failures correctly, do you get
an actual error in the logs/anywhere?

thanks,

Hi,
no, I don't see any errors in Foreman's log or in /var/log/messages.
Should I look elsewhere?
Also libvirt logs on the virtualization host show nothing special.

Thanks.
