Now you mention it, I think I remember reading about that before. The
cpuunits is really just a matter of percentages, isn't it? If I
understand right you could just as well start with a value of 100 for
a server and then in this case assign 67 (as 2/3) to this VE, and re
remaining 33 to remaining VE's. That would accomplish the same as
setting this VE to ~1390000 (2/3 of ~2085000) and use the remaining
~694000 for remaining VE's -- right?
Right, and strictly speaking vzcpucheck is not needed.... except for the
case
when you migrate some containers to a different node -- in this case those
units need some sort of a common denominator, and this is exactly what
vzcpucheck is trying to provide.

Short answer: vzcpucheck was written a long time ago, when the trees were
big and CPUs were small. Just divide the numbers it show by say 10 and
you'll be fine.

I have a server with 12 cores and vzcpucheck reports following "power
of the node":
[root@server16 ~]# vzcpucheck
Current CPU utilization: 646833
Power of the node: 2085210
Essentially I want to allow one container 2/3 of the power of this
hardware node but if I set the value of --cpuunits to more than 500000
it throws the error
[root@server16 ~]# vzctl set 1602 --save --cpus 8 --cpulimit 800
--cpuunits 500001
Bad parameter for --cpuunits: 500001
Setting it to 500000 works fine:
[root@server16 ~]# vzctl set 1602 --save --cpus 8 --cpulimit 800
--cpuunits 500000
Setting CPU limit: 800
Setting CPU units: 500000
Setting CPUs: 8
CT configuration saved to /etc/vz/conf/1602.conf
What am I misunderstanding here?
