Hello, According to the docs, vcpupin will use either cgroups or sched_setaffinity to pin vcpu threads to cpus. How is this decision made? I observe differences even on different hosts featuring the same version of libvirtd (1.3.1): on one host vcpupin affects cpuset.cpus (cgroup), and on the other it affects vcpu threads affinity (observed through taskset).
It affects both affinity and cpuset.cpus. Are there any differences in the host environment, or the domain XML? Also note that libvirt 1.3.1 is 2.5 years old now. Jano
