I'm looking for a way to configure the guest networking(including IP)

Is there a similar feature in KVM/Libvirt as the Invoke-VMScript in of
VMware's PowerCLI?
It allows you to run a script in the guest OS, even before the guest
has networking connectivity (the host talks to the vmtools agent
that's installed in the guest).
The QEMU guest agent (qemu-ga) has features that may allow you to do
this. I'm not familiar enough with it to give details, here are some
alternatives:
If you provide a kernel + initramfs externally (outside the guest disk
image) you can add files to the initramfs. This allows you to customize
boot up.
Alternatively you can use PXE booting to achieve the same thing.
Finally, you could edit the disk image using libguestfs or qemu-nbd
before booting it for the first time. This gives you a chance to
customize configuration and startup files.
