Hi,

Can someone please tell me if the virtual memory (privvmpages) is limited to the amount of RAM memory in the computer?

When I type the command vzmemcheck, this is what shows up:

[root@t248 ~]# vzmemcheck

The thing is. It seems to me that the RAM memory is underused... It shows that it's only 21% (210MB) used. The machine I'm running openvz has 1GB of memory. But, the Alloc memory is being overused, it shows that it's 145% used (1455MB). So, my question is, can I use the Alloc memory (privvmpages) to match up the RAM to be used? I just don't know where this virtual memory comes from or what resources it uses.

Please help?Smile
