Hi,
I have two sles10sp1 dom0, and 4 domUs. Two of the domU's can xm
migrate --live without problem, the other two cannot.
It ends up with the following error message:
ppsnfs101:~ # xm migrate --live FIS_DB ppsnfs101
Error: /usr/lib64/xen/bin/xc_save 24 24 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.
and in /var/log/xend.log I see the following:

both dom0 machines have more or less the same configuration, the domU hosts
too. any idea why two of the domUs can migrate well, but the others not?
kind regards
