I tried following your suggestion but same thing happens:
ss01:~# kvm -m 256 -boot d -net nic,vlan=0,macaddr=52:54:67:92:9d:63 \
-net tap -daemonize -vnc :15 -k es -localtime -cdrom \
/mnt/systemrescuecd-x86-2.0.1.iso -monitor telnet:localhost:4055,server,nowait
ss01:~# telnet localhost 4055
Trying ::1...
Connected to localhost.
Escape character is '^]'.
QEMU 0.12.5 monitor - type 'help' for more information
(qemu) stop
(qemu) migrate_set_speed 4095m
(qemu) migrate "exec:gzip -c > STATEFILE.gz"
Connection closed by foreign host.
ss01:~# ps ax|grep systemrescuecd
26564 pts/0 S+ 0:00 grep systemrescuecd
It appears that the 'migrate' command causes termination of the virtual
machine to these parameters as well.

I have not tried a migration where both source and destination have the
same characteristics (i386 installation and amd64 kernel).
Thanks for your reply.
Regards,
Daniel
