Tony,

Thanks for the interesting article!

Not sure which version of vzctl you use, but since vzctl-3.0.11, released some time in Aug 2006, it supports calling VE by names, e.g.:

vzctl create 202 --ostemplate debian-4.0-i386-minimal --name mydns

vzctl start mydns

vzctl enter mydns

A generic way to obtain a VEID using its name is something like

vzlist -H -oveid $NAME

UBC parameters for the given container can be obtained from /proc/bc/$VEID/resources.

Hope that helps.
