[one-users] Doing things a bit different, bypassing templates?

[Javier Fontan]

Hi,

Take a look at this post.

http://blog.opennebula.org/?p=4665

We use foreman for OS installation (PXE) in a similar way you are
describing. After installation PXE configuration is changed to tell
the VM to boot from HDD so you don't need to modify the VM. This is
done automatically by foreman.

Cheers
