[libvirt] [PATCH] qemu.conf: Mention virtlockd in @lock_manager description
When I played with virtlockd I was stunned by lacking
documentation. My frustration got bigger when I had to
read the patches to get the correct value to set in
qemu.conf.
Moreover, from pure libvirt-pride I'm changing commented
value from sanlock to lockd. We want to favor our own
implementation after all.
