We sometimes use the following awk form to filter the output of the
virsh command (mostly `virsh -r CONNECT dominfo NAME' - use
`virsh -r dominfo <dom id>' to test on the commandline) into a standard
format like
ID:6
NAME:ls3055v0
UUID:955c3b65-d013-547f-321b-9fea65439c40
OS_TYPE:hvm
STATE:running
CPU(S):4
CPU_TIME:433016.4:S
MAX_MEMORY:20000000:KB
USED_MEMORY:16384000:KB
AUTOSTART:disable
We do this to extract numbers out of physical quantities in a reliable
way.
