Yap.. sorry might be off topic..
- Yes, i split VE using command line vzsplit. So, I split 20, 40, 80 etc and i have those config files.
- The resource parameters are changing(decrease/increase) according to the amount of VE that i splitting..
- But start from splitting around 17 onward lower value, i.e.. 16, 15, 14,..., 10
- vmguarpages parameters wont increase from barrier 620736 pages. It still showing barrier 620736 pages on 17, and 16, ..., 10 config files.
- But cpuunits/other parameters increase/decrease accordingly on this situation.
Please have a look these splitted config files.

So compare the last two config, 20 and 10, all other parameters increase/decrease accordingly but VMGUARPAGES, PRIVVMPAGES, OOMGUARPAGES barrier parameters are not. So, my question is
- i have to manually set the amount OR
- is this normal and i'm missing something OR
- vzsplit can not split more than 2G+ of RAM OR
- the rest of RAM(around 1.5G+) reserved for HN?
But of course, i wont offer or package more than 2G+ for VPS hosting.. I just curious to know at least.
Thanks
