Hello,
Could you specify the exact model of your quad-core xeon cpu please?
I'm looking for VT processors well recognized.
Is it a Xeon E5300, or Xeon X5300 family?
Thanks for your answer, and sorry not to help with your issue.

with the mptfc driver, which is deliverd with this kernel, the I/O

Hello Tim,
thanks for your answer.
Every DomU in my solution have a 2 GB Swap
('phy:/dev/sda13,/dev/sdc1,w') for him self.
And every Dom0 and DomU boot over NFS, I use openQRM 3.1.2 from
www.openqrm.org
Any idea?
Best
