hi,all
please explain what does both agent do when migrate?
what do dest and src do?    it use libvirt's migration  or create a new vm throught vmCreate?

src calls vmCreate on dst to prepare storage & create a "hollow" VM
then trigger libvirt migration from src to dst
which in turn just starts underlying qemu migration from the src VM to the prepared dst VM

 
thanks
