@Serge correct - for security (and portability) reasons, we've decided to run ssh only and nothing else on the hosts - all other services run on guests - so the host is using one of it's own guests as it's DNS server. It's backup nameservers are on different hosts which are usually up, so we never noticed this issue - but this time, they were not available at the moment we rebooted. The result was all guests failed to start.
For now, we've just updated /etc/hosts on each machine to make sure they automatically resolve themselves even without nameservice - this seems to be a decent workaround for now. -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to libvirt in Ubuntu. https://bugs.launchpad.net/bugs/599342 Title: Temporary failure in name resolution To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libvirt/+bug/599342/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
