A 'migration: ' prefix would be nice for the commit title.

add dir mapping checks to check_local_resources
So, as long as there is a mapping for the target node, the migration
check goes through. Should it? I mean, nothing ensures that the contents
of the directory are the same on the target, or? What happens if they
are not?
Yes. This is similar to the PCI & USB Mapping. Nothing ensures that the
mapped device/directory is the same on the other host.
If the contents are not the same they will not be the same.
But this should not be a problem as long as nothing in a VM depends on
something in the virtiofs directory.
This is something the user should take care of.
Or am I missing something?
Is migration with a directory on a shared storage reliable? With all
cache settings?
I didn't encounter any problems.
Since the VM has to be powered off to migrate, I assume the cache gets
cleared & written to disk when virtiofs stops.
If you already tested these things, please share them in the commit
message (and maybe also docs). Otherwise, I know nothing without testing
myself ;)
Okay :)
