Re: [Users] vzmemcheck
Hi, I only have access to testing environments right now but these are commands I use: Guaranteed allocable memory: 2048MB Debian:/ # vzctl set 35 --vmguarpages 2048M:unlimited --save Not Guaranteed total allocable memory: 3072MB (barrier) Safety gap over not guaranteed allocable memory = 3072 * 125% = 3840M ( limit) Debian:/ # vzctl set 35 --privvmpages 3072M:3840M --save Out of memory guarantee. No processes will be killed if the VE consumes less than: 3840M Debian:/ # vzctl set 35 --oomguarpages 3840M:unlimited --save Kernel Space memory: barrier 50M limit 55M. Debian:/ # vzctl set 35 --kmemsize 50M:55M --save Note that this is not an efficient way of consuming RAM. It may be necessary to adjust the gap between barrier and limit of privvmpages.

Re: [Users] vzmemcheck
That means you are committing 457.95% of your memory, basically you have allocated quadruple the amount of ram that you have.
