There's CPU cgroups. It doesn't have exactly the ability you are after, but it is able to limit process(es) CPU usage. Maxing out CPU usage won't crash your server. The kernel will arbitrate sharing the CPU evenly among processes/VMs. --Brian Jackson On Thursday 02 April 2009 16:41:10 Francisco Mazzeo wrote: > Hello, > > I am a new user to KVM and was wondering if there was any way to > limit a VE from using up all the resources of the processor. > > > Right now I have a Quad core 2.5Ghz, I have a KVM VE (running windows > server 2003) and assigned 4 CPUs to it.
