As above, QEMU's locking is good enough to rely on for file based

Hi Daniel, thank you for the direct confirmation.
The flaws I mention with libvirt might actually finally be something
we
have fixed in 5.10.0 with QEMU 4.2.0, since we can finally use
"blockdev"
syntax for configuring disks. Copying Peter to confirm/deny this...
The main issue was that we were leaking locks on the backing chain.
This
should be now fixed with -blockdev as we call the appropriate apis to
lock/unlock the images but I didn't try it with virtlockd.
Certainly if there's still a problem now we have well defined places
where we know what's happening to images so it should be easy to fix
them.
Hi Peter, can I ask what do you mean with "fixed with -blockdev"?
Thanks.
