whenever someone says "I can't" but doesn't include an error message, its not clear what the problem is. Is the problem with your level of understanding or is it a technical problem? If the latter, send us the command and output you are seeing.

Hi,

Sorry this not "I can't" but "i don't know"

I find this commande for allocate 128Mo
page = 128*1024*1024/4096 ---> 32768

vzctl set 102 --privvmpages 32768:32768 --oomguarpages 32768:32768 --physpages 32768:32768 --vmguarpages 32768:32768 --save

And this for the memory information on the VE
vzctl set 102 --meminfo pages:32768 --save

But on the VE, swap memory as zero
102:~# free
total used free shared buffers cached
Mem: 65536 13300 52236 0 0 0
-/+ buffers/cache: 13300 52236
Swap: 0 0 0

How to allocate swap file?

Thanks

Sorry for my english

swapping is handled by the HN; the proc/meminfo file is adjusted by the meminfo option to vzctl and it seems swap is not adjustable, so it just displays 0. in the VE context, you do not know or have control over how much of your memory is in physical memory and in disk swap. it could all be in one or the other, or in both. The VE is clueless about where its memory is actually stored.
