Increase RAM of openvz container from command line

Drukpa

I tried the following commands from the node to increase the RAM of 110 container from 6GB to 8GB, but it does not seem to work. If I do a free -m it still shows 6GB.

vzctl set 110 --vmguarpages 8G --save
vzctl set 110 --oomguarpages 8G --save
vzctl set 110 -- privvmpages 8G --save

It says it successfully wrote to the configuration file, and the 110.conf file is as below (some details removed for privacy):

KMEMSIZE="2147483646"
LOCKEDPAGES="5000"

QUOTAUGIDLIMIT="10000"
HOSTNAME="REMOVED"

CPULIMIT="800"

CPUS="8"

From the above I can see that the MEMINFO value of pages:1572864 results to 6GB. Do I have to change that too? If I do vzctl set 110 --meminfo pages:2097152, then it shows as 8GB in my container, but now am lost if there's been a real change or not.

jar

Tried physpages?

Tried setting physpages, it says I dont have vswap.

/usr/sbin/vzctl set $ctid --vmguarpages {$ram}M --oomguarpages {$ram}M --privvmpages {$ram}M:{$burst}M --swap {$swap}M --save;

This is what I'm using
