Re: [libvirt] [REPOSTv2 PATCH v3 4/6] 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.
