Hi, I am totally new to this. But what I am looking for is to run oVirt nod=
e on a diskless x86_64 server board. I have to pxeboot and then mount the i=
nitramfs as the final root file systems. No disk or NFS is allowed.
Is this possible with the current release?
David

Currently, no, but it's an important feature that we're hoping to get in
the next release or 2. Our current high level design is posted on the
wiki [1]. There is also some effort going on by the archipel group to
make ovirt-node stateless as well [2]. We certainly welcome feedback on
the node-devel(a)ovirt.org mailing list or directly on the wiki.
Thanks

Mike,
What is the timeframe we are looking at? In 3 months? Will this involve Dracut-only
changes or much more?
Thanks.
David

The full feature described on that page is probably more in the 3-6
month time frame. The work that has been done for archipel will
probably be merged earlier, but no set time frame for that yet either.
The other issue is that there will probably need to be some changes made
on the engine side to support a purely stateless/diskless node. I can't
comment at all on timeframes for that though.

If you're willing to assist development of the feature by driving design
or patches, it'll be quicker :) If you care about schedule, then help
us push it along to meet your timelines

Hmm, interesting.. 3 months is reasonable if we can get a prototype running. Ideally I
will need to fit the images into an embeded space less than 200MB (it's my pxeboot
server).
We are certainly interested in the feature and is willing to be part of it. But where do
we start?
Any suggestions from you guys that I can take back to my team?

200MB shouldn't be a problem, the oVirt Node ISO right now is around
150MB iirc. So you should be able to fit kernel/initrd for PXE server
into 200MB

I think taking a look at what primalmotion has been doing with going
stateless for archipel would be a good place to start, and then seeing
how this could be generalized for use outside of archipel.
Our original thinking on 'stateless oVirt Node' was that we would use:
* some form of {PXE/DHCP/embedded USB stick with minimal config} to get
just enough info to boot the system, get the mgmt network interface
up and communicate to the mgmt server controlling the node
* once you've got that done, the remainder of the configuration can be
applied dynamically by the mgmt server (for example the oVirt Engine
through vdsm)
If you follow the above, this problem actually isn't too hard to solve,
I don't think.
