I'm testing 'vserver' for some organisation. They want me to test
everything ;-). Btw. I tried cpu scheduling. I set 1/5 of cpu for the
first and 4/5 of cpu for the second 'vserver'. Then I ran two identical
programs, each in one 'vserver'. It computed some floating stuff. After
each e.g. 1000 cycles it printed dot. I expected that there would be
five times more dots in the second vserver after some time. But the
numbers of dots were identical.
# cat /etc/vservers/test1/schedule

# cat /etc/vservers/test1/schedule

Is it the right way?
