Subject: [PATCH downstream-hack dev-6.6 0/6] Virtual Media DVD support
Date: Mon, 18 Mar 2024 23:34:39 +0300 [thread overview]
Message-ID: <20240318203445.29036-1-fercerpav@gmail.com> (raw)
Microsoft distributes their Windows Server images as ".iso" files suitable for
burning on DVD medium.
This patch series allows to use such images directly via the Virtual Medium
(jsnbd + Linux USB gadget subsystem) OpenBMC feature provided
functions/mass_storage.usb0/lun.0/cdrom is set to 1 by /etc/nbd-proxy/state
hook.
The code was taken from the latest rejected upstream submission [0] and massaged
to apply to the current dev-6.6 branch. Since the patches were written the
upstream gained support for images larger than 2 TB [1], unfortunately applying
this series disables it.
Tested by installing Windows Server via Virtual Media with AST2600-based BMC.
I'm sharing these hoping it might be useful to community, without any particular
plans or desire to integrate and maintain them downstream (though I might post
an updated version in the future if applying becomes non-trivial again).
An alternative to using this series for installing Windows on bare metal is to
educate your customers about a much faster (the files would be downloaded using
host network card and HTTP + CIFS) and easier to automate way provided by iPXE +
wimboot [2], also available as part of netboot.xyz [3].
