Could someone confirm if tunneled (encrypted) and tcp (unencrypted) are the only supported protocols for live migration of KVM guests.In the example posted in my earlier mail,a separate process is being spawned by qemu-kvm to perform migration.Does the qemu migrate command always spawn a separate process? Additionally,I'd like to know if there's a way I can check the QEMU monitor command and parameters passed to the QEMU monitor command when a command is executed through virsh.

Appreciate any pointers. <pre>For eg:(qemu) migrate -d "exec:cat >'/tmp/vm'" Thanks, Marc </pre> </blockquote></div>
