Hi Kouya,

   I'm excited that you're looking into making live migration "live",
but this is causing my migration test to fail.  For a simple NFS root PV
guest, I get this:

# xm migrate floater 10.91.73.214
Error: /usr/lib/xen/bin/xc_save 22 6 0 0 0 failed
Usage: xm migrate <Domain> <Host>
...

xend.log shows the following:
