Hi Itamar
In the Wiki I see references on attaching floppy/iso as a payload. Is it possible to trigger a bash script (with parameters), for example, inside the guest using this mechanism? If so, can you please point me to some documentation?
the payload is attached at boot. cloud-init is a sample daemon which at guest startup look up for payloads and acts on them. for example, the deltaclout project has a cloud-init extension to read from payload data it expects. http://bazaar.launchpad.net/~cloud-init-dev/cloud-init/trunk/view/head:/clou...
Thank you Shlomi

I'm looking for a way to configure the guest networking(including IP) dynamically, using a custom script, right after VM creation.
Is there a similar feature in oVirt 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).
currently, you can attach to the guest a "payload", and have a script in the guest expecting that payload and acting on it (which is what cloud-init does).
Native KVM/libvirt option will be good as well.
if kvm/libvirt allow it, you can use a custom vdsm hook as well.
Thanks, Shlomi
