Since you're open to hacking components together, here's another possible hack: you could create a gfs2 file system on the shared storage, and use file locks on gfs2 files. The gfs2 files could be the actual vm images, but they do not have to be. You could still use lv's for vms directly, and create empty files on gfs2 representing each lv. The virtlockd file locks would be acquired on the empty gfs2 files, representing the lvs. This is another indirect way of using dlm locks, since the gfs2 file locks are passed to the dlm.
