Virtio hdd самоподписаный драйвер

Для win2003
----------------------
I have followed the links, however even after signing the drivers myself, Windows 64-bit doesn’t want them. The only solution that I have found is:
- Install your Windows with 1 normal device (ide) and 1 virtio drive.
- When Windows is successfully installed, add virtio driver for the second disk.

I don’t know if it is really necessary but in cmd.exe:

Bcdedit.exe -set TESTSIGNING ON

See: http://msdn.microsoft.com/en-us/library/dd419910.aspx

Shutdown VM.
Change the first disk from ide to virtio, Windows knows the driver from the second drive and use it for the first which have just been changed.

There is probably a better solution to install but I don’t know it.

HOW SIGN YOURSELF:
Download Windows SDK for makecert and signtools: http://download.microsoft.com/download/7/A/B/7ABD2203-C472-4036-8BA0-E505528CCCB7/winsdk_web.exe

Generate certificate:

In C:\Program Files\Microsoft SDK\…….\bin
MakeCert -r -pe -ss TestCertStoreName -n “CN=CertName” CertFileName.cer

Sign driver:
SignTool sign /v /s TestCertStoreName /n CertName /t http://timestamp.verisign.com/scripts/timestamp.dll viostor.sys

Now if you right click on viostor.sys, you can see certified by “…”.


Для win2008
------------------
I finally got it to work permanently by signing the driver with a test certificate, putting Windows into testsigning mode and installing the driver.
(Hint: Microsoft has disabled the "DISABLE_INTEGRITY_CHECKS" option, which in earlier versions of Vista64 (and Win7 64 RC?) would allow installation of unsigned drivers)
I did the following:
1. Copy the Win2008 driver folder from the CD onto the HDD
2. Download DSEO 1.3b ("Driver Signature Enforcement Overrider 1.3b") - You DON'T have to turn off UAC!
3. Start DSEO and select to sign viostor.sys which you just copied to the HDD
4. Uninstall DSEO :)
5. Start up cmd as administrator
6. Turn on testsigning by entering: bcdedit -set TESTSIGNING ON
7. Restart computer
8. Install driver as described in the article above
