xl restore already takes a command line parameter to specify a
replacement config file. ÂWhy is that not sufficient ?

Sometimes, it's needed that modifying the third part, for instance mac address. I means that you can restore a vm having its own mac address varying with its vm-id from a three-parted state file template byÂ

modifying the relevant section.

You can't expect a guest to cope with its network interface changing
mac address under its feet. ÂSo this isn't a good example.

What do you mean by 'changingÂmac address under its feet'ïÂ
