Hi Daniel,
thanks for the update, I'll give it a shot today to set it up. In a
somewhat related note, are you aware of any work on getting secure
boot + UEFI working in a guest? There is a PoC patch on OpenXT
(https://github.com/OpenXT/xenclient-oe/pull/729) but was wondering if
there are any parallel efforts ongoing.

Thanks,
Tamas
