Thanks, so the problem appears to be that a feature is missing from the guest's precise kernel, which was present in the saucy (13.10) kernel.
Could you verify whether using the LTS backport kernel packages in the precies guest fixes the issue? ** Also affects: linux (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1353947 Title: Hypervisor with QEMU-2.0/libvirtd 1.2.2 stack when launching VM with CirrOS or Ubuntu 12.04 To manage notifications about this bug go to: https://bugs.launchpad.net/qemu/+bug/1353947/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
