[libvirt] Global domain cpu.cfs_quota_us setup

Hello all! I would greatly appreciate your help with some cgroup question. Libvirt xml has cpu tuning section and quota element in it. That parameter sets up cpu.cfs_cgroup_us for every domain's vcpu. I set it to 55555 and has such hierarchy of cgroups: cpu.cfs_quota_us (-1) | |-emulator/cpu.cfs_quota_us (-1) |-vcpu0/cpu.cfs_quota_us (55555) |-vcpu1/cpu.cfs_quota_us (55555) |-vcpu2/cpu.cfs_quota_us (55555) .... \-vcpuN/cpu.cfs_quota_us (55555) Is there any way to set up upper level quota limit via libvirt without setting every vcpu? So I'd like to get next hierarchy: cpu.cfs_quota_us (55555) | |-emulator/cpu.cfs_quota_us (-1) |-vcpu0/cpu.cfs_quota_us (-1) |-vcpu1/cpu.cfs_quota_us (-1) |-vcpu2/cpu.cfs_quota_us (-1) .... \-vcpuN/cpu.cfs_quota_us (-1) Thank you! -- Regards, Alexander Burluka
