OpenStack Compute (nova)

PXE Boot Instance

Registered by Angelo Matarazzo

Currently, compute instances must be booted from images (or snapshots) stored in Glance or volumes stored in Cinder. This blueprint aims to provide a design for booting compute instances from a PXE boot server, i.e. bypassing the image/snapshot/volume requirement.
In this use case the user cannot choose the NIC to use for booting and DHCP request is sent over each network interface attached to instance. The PXE boot server is another machine within a tenant/provider network.

    Preliminary commit: The original call chain has been changed. If booted_from_network parameter is true, image request methods are skipped: the image to boot is provided by a external PXE and not by glance.
