[Libguestfs] New tool proposal

[Wanlong Gao]

Hi Rich,

We just talked about a new tool virt-diff which can diff files
between two guest, suggested by Kamezawa Hiroyuki <kamezawa.hiroyu at jp.fujitsu.com>

things like below,
# virt-diff -Nru --guest=Guest0 --guest=Guest1 /etc/hosts

Any thought about this?

Another question, what do you think about implement iptables,
firewall, yum, rpm, etc into libguestfs?


Thanks,
Wanlong Gao
