Hi list,
issuing the command "virsh blockcommit --delete --pivot" (on a
previously created external snapshot/overlay) returns an error regarding
an unsupported flag warning stating "error: unsupported flags (0x2)". I
need to manually "rm" the affected file after the blockcommit.
A similar issue was reported many years ago here [1]. Am I missing
something, or is the "--delete" flag not supported?
The qemu driver still does not implement the flag. Yes, it's a known
issue for many years now, but it is surprisingly complex to come up with
semantics for deletion of an external snapshot in a way that doesn't
corrupt data, so no one has tackled that code project.
