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

Re: [Xen-users] live migration fails with device still active
I am sorry that I clicked Send to quickly. More information: dom0''s are 64-bit RHEL5.3 with RHN updates. The live migration works with test 64-bit domU and fails with 32-bit domU. Are there anything special I need to do for 32-bit domU ?
