Hi Chris,

Don’t mess with the disk and network lines in your config. You still need emulated disk to boot Windows as the firmware (SeaBIOS or ROMBIOS) does not have PV frontends. Once Windows starts and the PV drivers load they will instruct QEMU to unplug the emulated devices so that the PV devices can take their place.

As for recovering, it’s probably going to be tricky. Since you were doing a fresh install it’s probably quicker to start again. The other thing to do *before* you install PV drivers (and I suspect this is the root of your problem) is to enable test signed drivers in Windows. Windows 10 (even 32-bit) will not load test signed drivers unless you have done:

bcdedit /set testsigning on

Hope that helps,

Paul

Subject: [win-pv-devel] Win-pv driver install success fails to boot

Hello,

I am a previous gplpv user who recently came across this project and wanted to give a try to atleast help provide feedback and testing.

I downloaded the latest drivers via the tar files on this page:

http://www.xenproject.org/downloads/windows-pv-drivers/development-builds.html

I extracted and ran dpinst as noted in the readme txt for each driver and saw that in device manager it created some new devices. NOTE this is a clean install and did not have gplpv or any other drivers previously

I shutdown the domu, changed my disk and network lines to use the PV style:

'file:/mnt/vil1064/vil1064-ssd.img,xvda,w',

vif = ['type=netfront, bridge=xenbr0, mac=00:16:3D:37:A0:A3']

and when i tried to start it up, it gets stuck at windows 10 loading screen with the logo and the spinning wheel underneath. i left it for several hours and it never got any further nor did it bsod'd or reboot over and over.

i went back and changed my config back to emulated interfaces and windows 10 does not start via the original config either

did i miss some critical step(s)? any ideas why the OS wont boot? whats he best to remove the drivers and try again?

i am a fairly technical linux and windows user and willing to invest some time to anything that will help so please let me know if theres any more info or anything i can do to give you more data
