Hello,
It appears that CPU intensive tasks on the hardware node do kill completely the performance on the VEs.
E.g. Simply copying a big directory like a VE private directory on the hardware node, bringing CPU load to 20-25% or so, completely kills responsiveness of my VEs, making them basically unusuable.
Starting tasks with nice -9 doesnt help either.
Is there any way to limit the CPU usage of the Hardware node so that VEs can continue running ? Or can one guarantee minimum CPU time in VEs ?
As it stands I am unable to do essential maintenance tasks on the HN because VEs get effectively killed.
TIA for any input on the matter
I am running Centos 5
2.6.18-92.1.1.el5.028stab057.2
