E.g. if a domain is configured to use memory allocated from certain numa
nodes, we'd want to make sure the dest has sufficient memory amongst
those nodes.
Right. I was asking because I'm interested in the problem at the libxl
level. To the best of my knowledge, I don't think we do anything like
that in libxl for now, and I still am not sure whether we should... :-)
But these were just examples of things we may want to check before
starting the migration. I suppose there are better examples wrt
storage, e.g. does the domain have an attached DVD, ...
Exactly.
Do (if you know that) other drivers in libvirt do these kind of checks?
