[Users] usage of swap on host server
does openvz can use the swap partition on the host server for the VE inside it? because i have 2GB RAM and 2GB swap on the host server, then setup 2 VE with 1GB guaranteed RAM and 1.5GB burstable RAM for each VE. it seems that if the 2 VE burst the RAM usage more than 2GB in total, the host didn't use its swap partition to accommodate the burst need as I check the swap partition is always show 0 is it true that i can't use the host swap as RAM for VE? in other word 2GB RAM + 2GB swap != 4GB memory can be allocated for VEs?

Best Regards, Markus The VE can use the memory supplied by the hardware node. It does not matter if the HW node uses RAM or SWAP beside performance. If the HW node does not use SWAP you simply have not *used* but maybe only reserved more then 2GB in sum (HW-node + VE). You can check /proc/meminfo on the HW-node to see how much of your RAM is used.

Host system swap is definitely used then needed. PS in OpenVZ we do not understand terms such as burstable RAM.

From: Kir Kolyshkin [EMAIL PROTECTED] PS in OpenVZ we do not understand terms such as burstable RAM. Where have you got it from? As far as i know OpenVZ have garanteed and burstable RAM. (Xen does not have burstable RAM). And we use it fine. It also should use the HN's SWAP as additional memory for the VE's Danny. ___ Users mailing list Users@openvz.org https://openvz.org/mailman/listinfo/users
Re: [Users] usage of swap on host server
the problem is i'm starting to get error: fork: cannot allocate memory, and when it happens apache will show 500 internal server error and wont fix if i'm not stopping and starting it manually. any way to prevent this? I want the RAM allocation for the VE remains the same.

Hello Jerry, thanks for your suggestion, but other process also having the same problem, such as firewall and email server.

Take a look at the StartServers parameter in the IfModule prefork.c section of the httpd.conf file.
