Important! You have to turn on NET_ADMIN capability for container:
vzctl set $VEID --capability "NET_ADMIN:on" --save
Then restart the container
Install ipvsadm, then set all necessary modules to load at boot, and load them now.
Note: you probably don't need all of these, but I got sick of trying to find the minimal set and gave up :)
===== Bridge Utils =====
