I am trying to do a test live migration between my two Domain-0 using
RHEL5.3 but it fails with the error that the disk device is still active.
This disk in this case is an iscsi disk which both dom0 can see an
access without any problem. udev is used to make the device name
(/dev/iscsi )to be identical from the two dom0.
Below is the /var/log/xen/xend.log. Any advice is greatly appreciated.
Thanks,
Vu
