Hello,
When i use KVM (NX and Ubuntu) the system runs very fast, it's really good to work. But after 4 - 5 hours the VM is very slow. When i open or close a window the screen rolls up and down. It is not useful 
OpenVZ runs every Time fast 
.
When i look at "top", "htop".... there is no utilization. CPU 5-10 %, RAM normaly... I do not understand it! Why is kvm after some time so slow?
I test this on more then 10 machines. It is always the same. Also on a clustersystem with 5 machines the same (HPml350-G6) I fhink the hardware is not the problem.
Greetings and Thanks for all Help
