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
Yeah, that has never worked. I guess you need to pin the vcpus and then it might work. As your own example proves. Michal
