This had come up on the iPXE lists awhile ago, and I had the following
suggestion (at least for linux):
Setup radosgw, store your kernel and initrd there. Create an iPXE
script to boot off this stored kernel/initrd, and have the kernel know
how to mount a RBD volume directly.
This is a little complicated to set up, but should be you booting off
Ceph with a minimal amount of external parts. The hard part comes in in
booting operating systems that cannot use RBD volumes directly. I don't
have any suggestions there.

Hi all-

There’s a mention (last comment) about booting off an RBD through
PXE. I was wondering if anyone here has done this, and how it worked
out for you, and if you might have a more detailed example of how to
implement? Any general recommendations for or against this approach
as a means of booting diskless servers over the network from Ceph
storage?
Hi Joe,
I also need to figure this out in the next week or two. If anybody's
done it, I would love to learn from their experience, failing which, I
guess I'm going to have to bump my own head.
Regards,
Edwin Peer
