[libvirt] [PATCH 09/10] qemu: Add VM Generation ID to qemu command line
https://bugzilla.redhat.com/show_bug.cgi?id=1149445
If the domain requests usage of the genid functionality,
then add the QEMU '-device vmgenid' to the command line
providing either the supplied or generated GUID value.
Add tests for both a generated and supplied GUID value.
