Hi,

I'm performing live migration. I see something weird happening that I cannot explain:

Once I fire xen migration at the source:

[root@src ~]# xm migrate --live FC8.domU dest
Error: /usr/lib/xen/bin/xc_save 23 3 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.

[root@src ~]#

If I do a xm list, I can see the domain here:

[root@src ~]# xm list
Name                                        ID   Mem VCPUs      State   Time(s)
Domain-0                                     0   499     1     r-----   1517.6
FC8.domU                                     3   500     1     -b----      3.6


While at the destination, I see a hanging domU as :

[root@dest xen-images]# xm list
Name                                        ID   Mem VCPUs      State   Time(s)
Domain-0                                     0   502     1     r-----   1646.1
FC8.domU                                     3   500     0     -bp---      0.0


Can anyone help me with this save failed problem and it will also be great if anyone can explain me what exactly happened here.

Thanks,
Asim
