Documenting VMs

I have decided to sit down and document every VM I have now, was wondering if anyone had metrics to add to the list, my current list:

• OS
• version (for windows 7, Xp etc for linux kernel)
• automatic updates enabled
• failover
• RAM size
• back up frequency
• number of human users
• # of CPUS
• CPU feature lists
• number of NICs,
• host's name
• ip address in /etc/hosts?

EDIT: I am using libvirt with virt-manager
