Problem   (1)  Doing 5 VM live migration at the same time,  but there are only 4 VM migrate to another host.
                   (2)  The error code: Error: /usr/lib/xen-3.2-1/bin/xc_save 43 2358 0 0 1 failed
                   (3)   Is it bacause of the CPU number (there are only 4 CPU, but there are 5 VM waiting for live migration) ?

 

                   Thank you so much for your help!!  :)

Best regards,
Yogi Huang   &nbs p;
