,added UBC q/a
== General ==
; What is a Virtual Environment (Virtual Private Server, VPS, VE)?
; Who needs OpenVZ? How it can be used?
; What is veth and how do I use it?
: See [[Virtual Ethernet device]]
== User Beancounters ==
; How can I reset <code>failcnt</code> in <code>/proc/user_beancounters</code>?
: In short — only by stopping and starting a VE. In some cases you need to keep VE in a stopped state for a few minutes.
: Long answer: there can be many application who reads /proc/user_beancounters, and thus if you will reset it you gonna have problems with those other apps.
: Consider what happens if you will reset you sent/received packets/bytes statistics on the network interface — programs which reads will be screwed up.
: So the proper thing to watch for is not the current value of, say, failcnt, but whether it is increased (from the previous reading) or not. You can write a simple shell script to do just that.
