[libvirt-users] Protocols used for migration

Hi all, I'd like to know what are the different protocols used for migration of KVM guests on RHEL hosts.I'm actually interested in 'virsh dump' and virsh dump executes the qemu 'migrate' command.I understand 'exec' is one of the protocols. Appreciate any pointers. For eg:(qemu) migrate -d "exec:cat >'/tmp/vm'" Thanks, Marc
