latest windows-in-domU driver wisdom?
I find myself in the unfortunate position of having to run a windows 10
domU. (dom0 is NetBSD 9.2, which is why I'm writing here). I'd love
some guidance from anyone else in this position; I've been Googling in
the wider world of Xen for this stuff for the last couple days and keep
coming up with sparse and sometimes conflicting info; I get the sense
that most Linux users have moved away from Xen, so their anecdotes are
aging rapidly. Hopefully someone else running Xen and NetBSD has some
better (or at least more appropriate to my situation) guidance.
Apologies in advance for the Windows-heavy content of this message. :)
I've gotten as far as successfully installing and running windows 10 on
the domU; it runs, I can reboot it, but performance is terrible, as I
think should be expected from a baseline install. So, I figured the next
step was to install the Windows PV drivers available here:
Ignoring the odd choice of distributing Windows drivers as tar files, I
managed to get all the drivers copied over to my VM and installed - and
then the VM would no longer boot at all. After a few hours of fiddling
(and a complete reinstall), I figured out that support for "test signed"
drivers needed to be enabled in Windows, so I did that. I got a couple
of drivers installed OK (rebooting between each install this time, to
figure out which one is causing problems), and have run into a few of
them which, when installed, make Windows hang forever (or at least 10
minutes) during reboot. Once I've gotten a boot hang, I have to go
through the process of getting Windows into "Safe Mode" (which takes
5-10 minutes of babysitting the VM because I have to hit keys at the
right time, and also select from menus) and then uninstall the offending
Thus far, these drivers seem to have installed OK (and windows performs
somewhat better due to some of them):
and these drivers cause hangs:
Now, the xenvbd driver in particular seems like one that would improve
performance if it was working properly. Does anyone have suggestions?
Thus far, I've only tried the "9.1" versions of drivers; perhaps trying
the older versions might help?
Getting this working is exhausting; I'd appreciate any insight or help
anyone can give me. For the record, this is info on my dom0:
NetBSD 9.2 dom0
dom0 has 1G RAM
domU has 8G RAM, and 800G disk is allocated from LVM on top of a
