[libvirt-users] Libvirt LXC vcpu doesn't seem to work

Hi, I seem to have a problem when creating a LXC container through virsh. While virsh -c lxc:/// dominfo <container> shows up (for example) 2 VCPUs as defined, if I run a CPU intensive task (such as stress --cpu 10) it will max out 10 CPU cores on the host. If I echo "0" > /cgroup/cpuset/libvirt/lxc/<domain>/cpuset.cpus then the container is properly confined to just one CPU core. Subsequently, running stress --cpu 10 only one core on the host is maxed out. Does anyone know what syntax/config I'm missing, while installing the lxc container via virsh..to ensure that the VCPUs are restricted to the number defined? Thanks in advance
