CentOS virt - Jun 2015 - Question Kernel / KVM; Update Centos 7(.1)

Hello,

Have Centos a Repository with corrected or newer Packages for KVM.

On my brand new System ;-), but also with my older System. I have big problems 
with KVM guests "slow slow slow", the DomU's are also CentOS 7

virt-manager is also broken with the 7.1

The "old" Bug in the Kernel is really bad, I have several hundreds log
from
the vcpu0 Problem.

thank's for a answer,

You must be doing something wrong. I do not share this experience.

What exactly should be broken? Not on my side

I am new on centos, this is my first productive Server, but on my home i tested 
this over years, with no Problems.


I "mean" this is a kernel / qemu-kvm config problem, ?

CPU E5-2620v3
Chipset = C612

It is not possible to change the CPU z.B. "Copy from Hos"t crash the
virt-
manager, only the default is working. all other are broken. This is a fall 
back to the first screen.

It is not possible to install a DomU
