Hi,
I saw that freeing the dom after a migration takes place results in:
libvir: Domain error : invalid domain pointer in virDomainFree
Now I wonder, if this is the case, could a normale migrate function
'just' be:
domain = virDomainMigrate(domain, ....)
Or is this unsafe; for example as a domain migration fails?

virDomainMigrate shouldn't free the source domain ever. It should be
up to the caller to free it later once they've ascertained that the
migration was successful.

I don't see any code which free's the source domain, so I'm not sure
that's the problem.

I'll try to figure out if it is in my code, or that I can reproduce it
with some sample code.
