Hi to All,
I have a linux system running openzv , with over 10 containers .
When i run the command ps -ef , i see all the processes running on system.
the question is how would i know which process is for what system. without entering the containers.
Thank you

How do you get this to work on a 64 bit hardware node? It complains that glibc is not installed, but it is - in 64bit version though. I expect that's the problem...
# rpm -Uvh vzprocps*
warning: vzprocps-2.0.11-6.13.swsoft.i386.rpm: Header V3 DSA/SHA1 Signature, key ID 2425c37e: NOKEY

install i686 version of glibc
also you need a ncurses.i386 and ncurses.x86_64 installed on your system
glibc.i686 : The GNU libc libraries.
ncurses.i386 : A terminal handling library
ncurses.x86_64 : A terminal handling library
yum install -y glibc.i686 ncurses.x86_64 ncurses.i386
Debian GNU/Linux user since - Debian 2.2 (Potato)

Thanks much! I had to install ncurses-libs.i686 to install libncurses.so.5 and now vzprocps installs ok.
Still doesn't run though, both vztop and vzps falls over with alternatively "Floating point exception" and "Segmentation fault":
# vztop -C
01:06:10 up 2 days, 21:02, 1 user, load average: 0.12, 0.12, 0.06
631 processes: 629 sleeping, 2 running, 0 zombie, 0 stopped
CPU states: 4.0% user 0.8% system 0.0% nice 5.6% iowait 788.0% idle
Floating point exception
# vztop -C
01:06:10 up 2 days, 21:02, 1 user, load average: 0.12, 0.12, 0.06
631 processes: 629 sleeping, 2 running, 0 zombie, 0 stopped
CPU states: 4.0% user 0.8% system 0.0% nice 5.6% iowait 788.0% idle
Segmentation fault
# vzps

Yes this is on 2.6.32-042stab037.1, Scientific Linux 6.1.
> Anyway, looks like vzprocps would need a bit of love & attention
Absolutely! I can't understand how this tool has not been updated for years. It should be a cornerstone in managing an OpenVZ server!
Another tool I REALLY miss from Virtuozzo is vzstat or something similar showing a list with the load of each container on a hardware node, like below. Actually it could probably be improved a lot, but a tool that would just show the important key values like CPU, memory, IO, loadavg for starters would be really cool.

I hacked up this quick-n-dirty script that produce a usable output, even if it ain't too pretty:
#
clear
while true
do
tput cup 0 0
top -cbn1 | head -12
echo
for x in `vzlist -o veid -H`; do /bin/echo "$x: `vzctl exec $x cat /proc/loadavg `"; done
echo
iostat -dmN | grep -v ^sd
sleep 10
done
You might need to change the iostat line depending on your disks and configuration.
