[xingxing gao]

Hi,all,i am using libvirt to manage my vm,in these days i am testing
the libvirt snapshot ,but meet some problem:

the snapshot was created from this command:
snapshot-create-as win7    --disk-only --diskspec
vda,snapshot=external  --diskspec hda,snapshot=no

but when i tried to revert from the snapshot which created from the
above command ,i got error below:

virsh # snapshot-revert win7 1338041515 --force
error: unsupported configuration: revert to external disk snapshot not
supported yet
