[libvirt] KVM migration with uri = NULL

[Zvi Dubitzky]

What is the meaning of using virDomainMigrate () with NULL uri.
Looking at the code of  qemudDomainMigratePrepare2 ()/ qemu_driver.c,   I 
understand that it tries to perform a migration  to another 
VM on the same node  . Is that correct ?
Anyhow the code gets stuck while doing this with  KVM-84 driver which does 
ok a live migration between 2 different nodes  via QEMU  monitor

thanks
