Here are commands to help adjust the memory / RAM for an OpenVZ VPS: 64MB Guaranteed, 128MB Burstable cid=1000 vzctl set ${cid} –vmguarpages 64M –save vzctl set ${cid} –oomguarpages 64M –save vzctl set ${cid} –privvmpages 64M:128M –save 256MB Guaranteed, 512MB Burstable cid=1000 vzctl set ${cid} –vmguarpages 256M –save vzctl set ${cid} –oomguarpages 256M –save vzctl [...]
