Introduction

This page lists some important Proxmox VE 3x and Debian command line tools.

KVM specific

qm

To view a list of KVMs: 

qm list

vztop

This utility program can be run on the Node just as the standard Linux top . For information on the top utility please consult the corresponding man page, vztop provides certain additional functionality related to monitoring separate Containers running on the Node.

The vztop utility has the following functionality added:
