That's not entirely trivial then, especially for you, unless you want
to set up your own osstest production instance.  However, I can
probably do the osstest-machinery work if you will help debug it,
review logs, tell me what to do next, etc. :-).

We do both network boot and disk boot.  I think the BIOS disk boot has
to continue to work and boot the HDD.

There are no PCI passthrough tests at all.  For a while we had some
SRIOV NIC tests which were requested by Intel.  But they always failed
giving kernel stack dumps.  We kept poking Intel to get them to fix
them, or tell us how the tests were wrong, but to no avail.  So we
dropped them.

So any work in this area would be greatly appreciated!

Ian.
