    libvirt: Regenerates xml instead of using on-disk

    The libvirt.xml file is written on initial boot of the instance and
    may not reflect the current state of the vm if volumes have been
    attached. If the libvirt definition of the vm has been lost, it is
    safer to regenerate it rather than attempt to load it from the
    outdated file. This should properly bring back vms with attached
    volumes.

    Fixes bug 1073720
