Re: [Xen-users] Windows PV drivers

Are you able to advise what I might have done wrong in this process?
Seemes to me correct, I'm just missing a step, where the system asks for
wether or not to trust "Linux foundation", when installing the drivers?!
Sorry, I had already done this previously when attempting the installs, and I had set the option to always trust drivers from this source.
Start a CMD.EXE as admin, and pls see dpinst.exe /? options. I recommend
to first do a complete uninstallation (and if you have older drivers
like glpv, uninstall them as well).

By manually starting dpinst.exe you will have more options to see what
has failed. What is written in the system logs/application log? There
must be a reasoning there.

Before I got this email, I decided maybe I should uninstall the GPLPV drivers, so I did that, and then installed all the drivers and they all worked. Except now I can't startup the VM. It boots and sits with the spinning circle forever (overnight...) I can startup in safe mode, and tried to re-install all the drivers ( version 8.1.0 ) and they were all successful, but I still can't bootup in "normal mode", only safe mode will work.

Should I start over? (I have a LV snapshot I can revert to...)
If I start over, how should I proceed?
a) Remove all GPLPV drivers
b) reboot
c) Install all 8.1.0 version of drivers
d) reboot

Or skip B, or something else?

Thank you again for your help.


However, as a personal experience, I recommend for you to wait till the
final release of


(logo testing is just done, so we can expect the signed version withi
1-2 months hopefully)
Do you mean because it is easier to install, or because it is more
stable (fixes some bugs in 8.1.0)?
It is installed absolutely the same way, it has just a more mature more
compatible and generally better codebase.

Is it possible to simply install the current version of 8.2.0, and then
update when the final release is done?
It is, but currently those drivers are not signed, which menas, you have
to enable testsigning if you want them to work. (BCDEDIT.EXE

Hi all,

I'm in the process of upgrading from xen 4.1 to xen 4.4 and have a
number of windows domU's running Windows Server 2012R2 with one of the
ejb versions of the GPLPV drivers installed.

Can anyone advise which are the best drivers to install for production
use today, and how they went about installing them?

So far, I've managed to boot my testing domU under 4.4, but I can't
install the drivers form
https://xenproject.org/downloads/windows-pv-drivers.html even after
installing the certificate.

I would prefer to use debian testing, but would I perhaps be better off
switching to XenServer and using the XenServer version of the PV
drivers? Or can I use the XenServer version of the drivers with plain
debian + xen?

Would appreciate any advice from others who have managed to get this to
work well, especially in a production environment.
