sudo cpuset -g -p 1308
I guess commit message provides enough information, but I want to share some testing info. So, with qemu driver I get: virsh # vcpuinfo qemu VCPU: 0 CPU: 0 State: running CPU Affinity: yyyy virsh # Check the corresponding process using cpuset(1) tool from base system: pid 1308 mask: 0, 1, 2, 3
sudo cpuset -g -p 1308
virsh # vcpupin qemu --vcpu 0 --live 2,3 virsh # vcpuinfo qemu VCPU: 0 CPU: 0 State: running CPU Affinity: --yy virsh # Now cpuset(1) says: pid 1308 mask: 2, 3
Now, do:
sudo cpuset -l 0-3 -p 1308
And check back again: virsh # vcpuinfo qemu VCPU: 0 CPU: 0 State: running CPU Affinity: yyyy virsh # Roman Bogorodskiy (1): BSD: implement virProcess{Get,Set}Affinity src/util/virprocess.c | 39 +++++++++++++++++++++++++++++++++------ 1 file changed, 33 insertions(+), 6 deletions(-) -- 1.8.4.3
