    fix the vms turn transient after libvirt pod restarts

    After libvirt pod restarts, the virtual machines created before
    turn transient ,then opetrate these vms ,nova-compute will throw
    exception. This is because that the directory /etc/libivrt/qemu
    in pod contains vitual machines xml files and it is temporary,
    the xmls files disappear after the pod restarts, so we mount it
    to hostpath /etc/libvirt/qemu.
