It seems there is another problem with my configuration that causes libvirt to have problems with autostarting virtual machines. I am using software RAID 1 with mdadm and my virtual machines are running on an LVM2 partition on md0. It seems the LVM2 volume is not yet available at the point where libvirt tries to start my virtual machines:
libvirtd: 20:42:16.345: 1389: error : qemuAutostartDomain:275 : Failed to autostart VM 'ns': unable to set user and group to '114: 125' on '/dev/mapper/storage-st0': No such file or directory libvirtd: 20:42:16.346: 1389: error : virSecurityDACSetOwnership:125 : unable to set user and group to '114:125' on '/dev/mapper/s torage-st1': No such file or directory So it seems at this point it is not the bridge that is causing problems, but it is mdadm in combination with LVM2. According to my /var/log/boot.log the mdadm monitoring daemon is started after libvirt. But I'm not sure if the monitoring application has anything to do with it. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/495394 Title: autostart almost always fails on boot time host -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
