^^ Prepare shared disk image

Usually, you will use `nfs` for this. Edit `/etc/exports` and add something like (if your local network is 192.168.1.x):

.pre
/rest 192.168.1.0/255.255.255.0(rw)
.pre

And start `nfs` server

.pre
dpavlin@llin:~$ sudo /etc/init.d/nfs-user-server start
.pre

^^ New target

Mount shared storage and run qemu which will receive running machine

.pre
dpavlin@squeak:~$ mkdir mnt/rest
dpavlin@squeak:~$ sudo mount 192.168.1.13:/rest mnt/rest/
dpavlin@squeak:~$ ls -al mnt/rest/iso/gparted-live-0.3.9-4.iso
-rw-r--r-- 1 dpavlin dpavlin 98347008 Oct 9 17:31 mnt/rest/iso/gparted-live-0.3.9-4.iso

dpavlin@squeak:~$ kvm -cdrom mnt/rest/iso/gparted-live-0.3.9-4.iso -incoming tcp://0:4444 -monitor stdio
.pre

^^ Running source

.pre
dpavlin@llin:~$ kvm -m 128 -cdrom /rest/iso/gparted-live-0.3.9-4.iso -monitor stdio -no-kvm
QEMU 0.9.1 monitor - type 'help' for more information
(qemu) migrate tcp://192.168.1.30:4444
.pre

We use `-no-kvm` to disable kvm because our target machine doesn't have vmx|svm support!
