[libvirt] [PATCH 1/5] qemu: Only set group_name when actually requested
We were setting it based on whether it was supported and that lead to
setting it to NULL, which our JSON code caught. However it ended up
producing the following results:
$ virsh blkdeviotune fedora vda --total-bytes-sec-max 2000
error: Unable to change block I/O throttle
error: internal error: argument key 'group' must not have null value
