Hi all, how to check the LVE works? I use:

# dd if=/dev/zero of=/dev/null bs=1024k
# for i in 1; do while : ; do : ; done & done

Users may abuse the server ??

When you copy from /dev/zero to /dev/null --> you never hitting the disk, and io limits do not apply as the result (only CPU limits are).
Do the same with real files instead.
