I'm facing similar problem in openstack/nova-compute context We are using libvirt as default KVM to spawn the instances.
I faced the problem ONLY when the directory where it creates the console.log was nfs mounted (Not local disk path) Indeed I too have <serial> in the XML file -which is where the problem occurs. But when using local file system, everything works OK. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/632696 Title: libvirt won't start a VM with serial or console To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libvirt/+bug/632696/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
