As pointed out by Dan here:
https://www.redhat.com/archives/libvir-list/2009-October/msg00784.html
We should be using the same logic for collision prevention and domain redefinition in
the migrate routines as we use in create/define/restore.
Cole Robinson (3):
qemu: Remove compiled out localhost migration support
qemu: Break out function to check if we can create/define/restore
qemu: Use same create/define overwrite logic for migration prepare.

New subject: [libvirt] [PATCH 1/3] qemu: Remove compiled out localhost migration support
Pretty sure this would deadlock now that we have proper locking, so
remove the code.

I've pushed this patch since it is separate from the rest. I'll post a
more complete patch with the other driver changes you suggested.
Thanks,

How about putting this into src/conf/domain_conf.c - this same logic is
needed for LXC and UML drivers too.
Something like
virDomainObjIsDuplicate(virDomainObjListPtr doms,
virDomainDefPtr def,
unsigned int check_active);
