[kernel-xen] Centos7 Dom0 IO performance

[Christoph Kaminski]

Im afraid it wasnt the solution, with centos7 as domU it is much 
better/faster but I still have a IO problem on the NFS domU...

Any other hints for me to make it faster? (except buy new hardware, it 
was fast enough with centos6 as dom0)
