Hy all. Inside a fresh VE, created from the basic conf, based on etch template, if I start to download from kernel.org, the download starts at a good rate but in some seconds it slows down to 0. normally, in the host os, I can dl from kernel.org at 10Megs/sec. Inside a VE I even cannot finish downloading the kernel source, the most it comes dow is 4MB.
The server is a core2duo with 1,5g ram, and 2 VEs. Both VEs akt like I descrbed.
Any ideas?
here are the examples:
HOSTOS:/home/eliast# wget http://www.hu.kernel.org/pub/linux/kernel/v2.6/linux-2.6.22. 5.tar.gz

the basic conf is an extremely conservative VPS with 24MB RAM and everything tuned down
use the vzsplit utility to output an 8 way split of your hardware. compare the output of vzsplit with the conf of your VPS and you will see the problem
that was the solution but here is another way to check what is happening inside the VPS
cat /proc/user_beancounters
