Perhaps enable the debug logging of libvirt [1] to determine what it's
spending its time on?

The second attempt was a mere 2 hours with a bit.

Am I the only person having these issues with libvirt and Octopus release?

Subject: [ceph-users] Re: Octopus upgrade breaks Ubuntu 18.04 libvirt
A quick update.
I have done a fresh install of the CloudStack host server running Ubuntu 18.04
with the latest updates. I've installed ceph 12.x and connected it to
Cloudstack which uses kvm/libvirt/ceph/rbd. The rest of the ceph services
(mon,mgr,osd,etc) are all running 15.2.3. Works like a charm.
As soon as I've updated the host server to version 15.2.3, Libvirt stopped
working. It just hangs without doing much it seems. Common commands like 'virsh
pool-list' or 'virsh list' are just hanging. I've strace the process and
it
just doesn't show any activity.

The ceph itself seems to work, i.e. I can execute ceph -s / rbd -p <pool> ls -l,
etc. That produces the output. It's just the libvirt seems to be no joy.
The version of libvirt installed is:
libvirt-bin 4.0.0-1ubuntu8.1
Any idea how I can make ceph Octopus to play nicely with libvirt?
Cheers
Andrei
