Description of problem:
Now virt-manager GUI can only support creating internal snapshots for vm which disk format is qcow2, but libvirt has support creating external snapshots for vm which disk format is qcow2, raw and so on, we hope virt-manager should also suppport it.

virt-manager-1.3.2-1.el7.noarch
libvirt-1.3.4-1.el7.x86_64

qemu-kvm-rhev-2.6.0-4.el7.x86_64
