sw == software?
lm == live migration?
Maybe there is a name that is clearer. What are these virtqueues called?
Shadow vqs? Logged vqs?
Live migration is a feature that uses dirty memory logging, but other

be associated with live migration.

We talked about the possibility of moving this into the generic vhost
code so that devices don't need to be modified. It would be nice to hide
this feature inside vhost.
