Hi,

does xen/qubes offer an ability to adjust vCPU priorities dynamically or limit the vCPU usage for some VMs from dom0.

Similar to cpulimit or nice.

Use case: sometimes some VMs tend to consume to much cpu and block other VMs currently active. I'd like to reduce their CPU priority without shuting them down and decrease amount of vcpus.

Thanks in advance, P.

To do this directly in Xen I think you have to use 'xl sched-credit2'
command. See 'man xl' for details.
