or you'll get BSoD's on attempting the upgrade. I'm sure there's a

to make this a bit cleaner (eg require a reboot instead of crashing)
but
I don't know how at this point.

Bad, thing is that win2008 enforces singed drivers, so someone have to
deal with this, also win2008 dowsn't seem to have a boot.ini anymore,
so
we have to use bcdedit.
I'll have a look on these but sounds ugly.
I think you can tweak the registry to turn off the signing requirement.
In the long term I may look at the possibility of getting the drivers
signed, but this costs money so I'd have to charge something for the
signed drivers to recoup the costs, unless the amount was tiny. The
source and unsigned drivers would remain free of course.
At this stage, there are definitely a few things in the drivers that
Microsoft would frown upon, so passing the WHQL testing is probably not
possible at this point.

Ok, i've done some code reading yesterday, so i got this.
adding GPLPV using bcdedit enables the drivers, adding
DISABLE_INTEGRITY_CHECKS make the system booting again.
Currently i'm working on setting both with an easy configurebootloader.bat.
The blockdev stuff works the system boots and is looks pretty stable.
I performed some hdd reading benchmarks with interesting results, I'll
have to check them first, and complete them with write testing.
But one result is clear, using qemu adds the benefit that the dom0 seems
to use ram caching, so on a quite powerful machine the qemu stuff looks
partially faster, but i think when i give the dom0 less ram this will
disappear.
Good is that using the PV blockdev driver there is no significant
systemload in dom0, with qemu one core runs at 100%.
So, far some testing is needed but when the network stuff works also,
i'll have a look on the signing stuff, afaik it must be signed at all,
not necessarily by microsoft. So I have to check if i could use my sign
for that, hopeful that DFN or CA-Cert are at least a bit trustworthy ;)
