Yep, a virtual CPU is just a process on the host Linux system. > So, this sounds feasible... except if virtual CPUs must have time shared equally > as the VMWare co-scheduling explanations imply. A scheduler for threads / > processes presumably wouldn't guarantee such a thing? I think cgroups is the solution, if you want to guarantee resources to some guests. I haven't tested it with KVM, but perhaps "nice" and "ionice" can be useful as well...the guests are just Linux processes after all. > Maybe I'll go and investigate the KVM list.... :) Best regards Kenni _______________________________________________ CentOS-virt mailing list CentOS-virt@xxxxxxxxxx http://lists.centos.org/mailman/listinfo/centos-virt
