Hi Chris,
I haven't tested whether it works but theoretically it should be possible imo. I
don't see why you would want to do this though, but would like to understand
your reasons. Why not just create OpenStack images and let OpenStack take care?
I have some code that is designed to run on bare-metal servers that boots some
nodes off of other nodes and I'd like to test it with OpenStack instances
instead of needing physical nodes.
Some stuff that you need to care off if you would use PXE server in VM and boot
other VMs via PXE:
* ARP spoofing protection. Neutron by default(maybe not all drivers) has ARP
spoofing protection, you will have to either make sure that your PXE server
assigns the IP via DHCP that neutron has assigned to the instance.
Alternatively you can disable ARP spoofing for a specific neutron port with
`neutron port-update $port_id --allowed_address_pairs list=true type=dict
ip_address=0.0.0.0/0` <http://0.0.0.0/0`>
* Enabling cloud-init in your images that you're booting via PXE server. (May
be optional but recommended)
Thanks for the tips.
Chris
