Hi Julio, I'm using /usr/bin/ctr (containerd) with kata. Would setting the --cpuset-mems through docker help in my case? Thanks, Al On Mon, Nov 11, 2019 at 8:42 AM Montes, Julio <julio.montes@intel.com> wrote:
Thanks,
seems like by default the container engine that you're using tries to assign both nodes (0,1) to the container, unfortunately inside the VM (where the container is created) there is only one node (0), as a temporal workaround, can you change this behavior? (i.e docker run --cpuset-mems="0" ....)

Hi Al
how many memory nodes have your system? ( ls /sys/devices/system/ | grep node | wc -l )
* ls /sys/devices/system/node | grep node | wc -l
can you change the number of cpuset-mems to 0? for example in docker: docker run --cpuset-mems="0" ....
