[Libguestfs] [RFC PATCH] virt-sysprep:add ipconfig for preparation
Hi Rich:
I just send a patch to request for your comments,
then will do further work about this.
things like this:
[root at Allen ~]# virt-sysprep
--ipconfig="eth0:192.168.1.2,255.255.255.0,192.168.1.1"
--enable=ipconfig -d clone-6u1
OR
[root at Allen ~]# virt-sysprep -d clone-6u1
Please comments.
Thanks
-Wanlong Gao
