file based migration not working

hi

i was reading http://kvm.qumranet.com/kvmwiki/Migration and trying the "migration file://" and "migrate "exec:" migration methods. both giving me errors.

(qemu) migrate file:///tmp/vm.state
migrate file:///tmp/vm.state
unknown migration protocol: file:///tmp/vm.state
migration failed
(qemu)

(qemu) migrate "exec:gzip -c > /tmp/vm.state" migrate "exec:gzip -c > /tmp/vm.state"
unknown migration protocol: exec:gzip -c > /tmp/vm.state migration failed
(qemu)

are these methods not supported?

i'm using kvm-78 (self compiled) on debian etch with kernel 2.6.26 (backports.org).

ok, i see that they are missing in sourcecode right now because of the new migration implementation.

and i've seen that exec is reintroduced in qemu-svn.
