libvirt users - Apr 2012 - Regarding persistence of VM's after live migration (virDomainMigrateToURI() problem)

Hello
I am working with 3 host machines each running xen with shared NFS storage.
I am working on automatic load balancing if one host is over utilized and
another is under utilized by measuring the utilization from xentop. I am
facing a problem after migration of VM. I am setting the flags ( 1| 8| 16)
in order to do live migration, persist VM on destination, undefine host
from source. After migration if I shut off the migrated VM on destination
host it does not persist. I am using the migrateToURI() API for migration.

Please help how to make VM persist on destination.

Thank you,
Tasvinder Singh

There's a flag you can pass to the migration API, VIR_MIGRATE_PERSIST_DEST.
