[vserver] oom-killer killapps on hosts not not guest

Hi,

I've got a test server with 8Gb RAM
setup guest with rss.hard=90000 rss.soft=40000

now run
stress --cpu 4 --vm 8 --vm-bytes 50M

Got oom-killer on host killing applicatioin on not guest but on host.
How to avoid this?

I've tring to setup vm.overcommit_memory=2 which doesen't help

The only option seems to be
vm.oom_kill_allocating_task = 1

Is it a right way to do it?
