To do this,
1. we can use one dhcp server to assign ip for them, and bind the MAC to
it's ip. But we got many many machines, so this is not easy to operate for
admins.
Maybe not the easiest, but this really is the best approach - manage
your own dhcp server to assign ip addresses based on the mac addresses
you have assigned to each VM.
2. we can just create the vm and then let the client to config the ip
from
within the operating system. But the client don't want to, and sometimes in
fact they should not be authorized to do that.
Are there any way else to do this? I mean is there some API for that we can
use? or just mount the vm image file and change the network configuration
file?
If any API for that, can we change the config while the os in the vm is
running?
libguestfs can be used to modify offline guest images; it can probably
be used to modify IP addresses for each guest before you start them up,
although for a formula for doing that, you may be better off asking on
the libguestfs lists.
