Very well.

No? Oh, OK. That's weird.

Yeah, that's normal. Also note the somewhat weird gateway. :o)

I usually use one of my sample configs as a template for VPS creation. Here is 
my 20% config sample from one box:

#> cat /etc/vz/conf/ve-20_percent.conf-sample

# Configuration file generated by vzsplit for 5 containers
# on HN with total amount of physical mem 8073 Mb
# low memory 814 Mb, swap size 4095 Mb, Max treads 8000

NUMPROC="800:800"
QUOTATIME="0"
DISK_QUOTA=yes
QUOTAUGIDLIMIT="10000"


Note the last three parameters above, which specify the quota related stuff.

I typically then create a VPS this way:

/usr/sbin/vzctl create <VPSID> --ostemplate name.tar.gz --config 
20_percent.conf

Once it's created, I set the network related info:

/usr/sbin/vzctl set <VPSID> --nameserver "192.168.0.1" --hostname www.test.com 
--ipadd 192.168.1.1 --onboot yes --save

That should do the trick.
