Re: [Xen-users] live migration fails with device still active

[vu pham <vu@xxxxxxxxxx>]

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 ?

Thanks,
Vu
