Xen project Mailing List

Hi Paul and Fabio,

I haven’t reported back, but I wanted to let you know what I did:

1. All the Windows PV drivers build successfully with ‘build.py free nosdv’

2. Enabled Test Build

a. Opened the command prompt as Administrator

b. bcdedit.exe –set TESTSIGNING ON

c. Reboot

3. Installed XenBus and Reboot

4. Installed XenIface and Reboot

When I installed either XenNet or XenVbd, this caused a hard crash on reboot. The way to work around this issue is to reboot into a Last Known Good configuration and uninstall XenNet and XenVbd. I do not know what the issue is at this point. I have updated to Xen 4.5 and I’m using CentOS 7 with a Xen enabled kernel configuration. My DomU is Windows 2012 R2.

Although I’ve enabled netbk and blkbk in the CentOS 7 kernel, how do I verify if these devices are successfully running in Dom0?

Thanks,

Christian

Hi Christian,

The cert is a test cert so you’ll also need to make sure testsigning is on. It may be that dpinst is vetoing installation of a test signed boot start driver unless testsigning has already been enabled (it certainly pops up a dialog warning of this if you don’t use /C). I’ll see if I can repro what you’re seeing though. There’s probably more info on the failure in c:\windows\inf\setupapi.dev.log too.

Paul,

Thanks – I’m disabling SDV and everything builds fine. However, I can’t install the Xenbus package on Windows 2012 Server R2.

Under Other Devices, there is a PCI Device in device manager which appears to be the XenBus:

I’m using Xen 4.2 and using the default upstream QEMU. I’ve also installed the PFX file c:\xenbits\pvdrivers\win\xenbus\src\xenbus.pfx to be sure that there is no issues validating the driver.

Any help would be appreciated.

Thanks,

Christian

Christian,

I’ll have a look at the latest code. In general though SDV builds are a bit fragile. SDV has a tendency to leave log files locked causing weird failures on a fairly random basis. Unless you really want the SDV output I’d recommend building without it in the normal case. If you do want the output I suggest only running it in a freshly cloned repo where it has never been run before.

Subject: [win-pv-devel] Building Windows PV Drivers - Fails with Static Driver Verifier

Hi Paul,

Today I tried building the Xenbus drivers with ‘build.py checked’, but the build fails. If I build without running SDV (Static Driver Verifier), everything is fine. There are some warnings (as shown below) and the projects in the solution are setup to treat warnings as errors.

What should I do to use the SDV to verify the PV drivers? Is this a known issue and I should just disable SDV?

Thanks for your help,

Christian
