Dear all
The following process is about trying to do the " live migration at the
same time with 5 Virtual machines ", but there is somthing problem with it.
Process:
yogi-pc2: # xm migrate --live vm01 pc2 & xm migrate --live
vm02 pc2 & xm migrate --live vm03 pc2 & xm migrate --live vm04 pc2 &
xm migrate --live vm05 pc2[1] 29983

[4] 29986
Error: /usr/lib/xen-3.2-1/bin/xc_save 43 2358 0 0 1 failed
Usage: xm migrate <Domain> <Host>
Migrate a domain to another machine.
Options:
-h, --help Print this help.
-l, --live Use live migration.
-p=portnum, --port=portnum
Use specified port for migration.
-r=MBIT, --resource=MBIT
Set level of resource usage for migration.

vm07 1303 128 1 -b---- 39.2
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

The lack of memory caused the problem! I try to give more memoy for the target system and the migration success. Thanks for your help!!
