XEN Server Status Monitoring Command Cheat Sheet

in , ,

The xm command is the main command line interface for managing Xen guest domains. The program can be used to create, pause, and shutdown domains. It can also be used to list current domains, enable or pin VCPUs, and attach or detach virtual block devices.

Please note that before running any one of the following command you must run xend ( Xen control daemon aka service) and must be run as privileged user. Running xm command as non root will return an error.

I hope following XEN status monitoring cheat sheet will save your time.

xm uptime

xm list

Finding the IP address is not that simple since every guest can be configured internally without a care from the dom0 since it usually only knows the mac address and has MAC rules in iptables for each of the guests, not their IP addresses. BUT, if they are all in the same subnet and are (eg) DHCP clients, you could run nmap -sP 192.168.1.0/24 and ping sweep the network then match what the dom0 knows as the MAC address against the results of the ping sweep. crude yes but why get yourself into an issue like this in the first place?
