Shouldn't this be virDomainChrDefFree(chr)?

If you never hit the if condition, disk will be left pointing to one of
the disks in def, and will be freed during cleanup. I think you want to
set disk = NULL after this look is finished as well, don't you? (Either
that, or just use a different variable).
Both good points. I'm squashing this in to create v2.
