somebody please remove or correct the entry (to remove the insecure
vprocunhide advice).

i tried, but i really don't want to create an account and the captcha was
impossible to please (ie "what is the name of this project?" linux-vserver,
Linux-Vserver, Linux-VServer... all wrong according to the all-knowing wiki).

{{Question
|Question=I want iotop on the host to display all guest processes to give me a nice overview of I/O usage.
||Details=You must unhide /proc/vmstat for context 1. Recommendation: put the following in a script called "viotop" and modelled after "vtop".

# setattr --watch /proc/vmstat
# vcontext --migrate --xid 1 -- iotop
