We have several containers on one machine and would like to reserve some memory for the global zone. capped-memory only allows max physical/swap and setting a max on each container isn't an option. The server has 32GB physical and 30GB swap. Currently there are ten containers on it. Normally only a couple of the containers are active and consume from 10-15GB. We run into issues when a few of the containers become active or when we have a process in a container consuming all of the memory. When this happens we can't fork() in the global zone to halt the local-zone hogging the resources. Is there a way to reserve memory for the global zone so we can have enough resources to run administration commands from the global when a local-zone ends up consuming all of the memory resources?
