Hi,
I have been playing with KVM and was wondering about the following question:
is there a resource configuration setting that would enforce a fraction of
CPU to be guaranteed for a KVM guest? What I have on mind is something
similar to the "reservation" setting on VMware (used to be called minimum
CPU), which guarantees a number of CPU cycles to a VM. Also, any
configuration setting similar to CPU/Memory Shares setting in VMware, which
will kick in under contention for resources?
Regards,
Yuksel Gunal

VM is like any other process in Linux, you can use cpu controller,
cgroups or any other scheduling option for your VMs.
