[Bug 1583009] Re: Error starting domain since update

[Marc Gariépy]

Just had this issue with upgrading from Newton > Ocata via Openstack-
ansible.

the issue I noticed it that is seems that only a reload "systemctl
reload virtlogd.service" isn't enough.

after instlalling the update, I can list the instances with  "virsh
list" but when I use nova to interract with the vms
(start,stop,create,...) virsh just hangs.

restarting libvirtd make the virsh list working again but nova cannot do
actions on it.

restarting virtlogd seems to fixe the issue, maybe the pkg update should
restart the service instead of just reloading it ?


here is the update i installed on the server:
2018-01-25 21:16:14 upgrade libvirt-bin:amd64 1.3.1-1ubuntu10.15 2.5.0-3ubuntu5.6~cloud0
2018-01-25 21:16:15 upgrade libvirt0:amd64 1.3.1-1ubuntu10.15 2.5.0-3ubuntu5.6~cloud0
2018-01-25 21:16:20 upgrade python-libvirt:amd64 1.3.1-1ubuntu1.1 3.0.0-2~cloud0
