Note that you can configure that in the per-vserver configuration file
(/etc/vservers/*.conf). There is the ULIMIT line
ULIMIT="-m 8192 -d 8192 -v 16384"
and it will be used anytime to start the vserver. You can also use the S_NICE
entry to control the nice level of every process in a vserver (the ceiling in fact
since a process may request to be even nicer (less priority)).
