[libvirt] [PATCH] BSD: implement virProcess{Get,Set}Affinity



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:

> sudo cpuset -g -p 1308
pid 1308 mask: 0, 1, 2, 3
>

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:

> sudo cpuset -g -p 1308
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 #
