libvirt users - Apr 2011 - 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

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.

Thanks,
Marc
