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 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1583009 Title: Error starting domain since update To manage notifications about this bug go to: https://bugs.launchpad.net/cloud-archive/+bug/1583009/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
