In "/opt/kata/bin/kata-runime update --help", it has the "--cpuset-mems value" option. I think this works if there is already a kata container running. Is there a way to set the cpuset-mems to 0 in the configurations.toml file (for example) so that all the kata containers uses the NUMA node 0 on memory usage? In my environment, the kata containers are started through CRI API. If not possible to preset cpuset-mems for all kata containers, I have to find a programmatic way to set the cpuset-mems.
