I'm using LVM volumes for my HVM disks just fine. Did you try specifying
the full name of the device with the "/dev/" prefix? For example:
disk = [ 'phy:/dev/data/faitest-client-generic-hvm-disk,ioemu:hda,w']
My HVM domU config file has:
disk = ['phy:/dev/virt-blkdev-backend/hvm1,ioemu:hda,w',
'phy:/dev/virt-blkdev-backend/usr,ioemu:hdb,r','phy:/dev/virt-blkdev-disk_io_test/hvm1,ioemu:hdd,w']
and it works fine. The first entry is the domU boot disk with the root
file system partition, the second entry is the read-only /usr file system,
the third entry is a blank disk for testing disk I/O.
