Description RHOS Integration 2013-12-12 13:44:35 UTC

Cloned from launchpad blueprint https://blueprints.launchpad.net/nova/+spec/libvirt-empty-vm-boot-pxe.

Description:

Use case:

We want to test OS installer like anaconda or debian-installer or any other installer which is able to install OS via network. In order to test it we need to create two-node environment. On the first node we will install tftp and http servers. Then we call neutron API to set all necessary DHCP options. Then we will start the second node which is empty. This second node will try to boot via PXE. It will send DHCP request and DHCP server (neutron managed) will offer IP address and next-server option which will point on the first node.

Concerns:
 At the moment we can not use openstack for such a case.

Implementation:
We are going to modify libvirt driver to make it able to create VM with empty disk image and make this VM able to boot via PXE.
