[Xen-users] Disabling driver signature enforcement for Windows DomUs

[Adam Wead <awead@xxxxxxxxxxx>]

Hi all,

After loading the GplPV drivers for Windows Server 2008, I wanted to  
get rid of the annoying F8 option when rebooting each time.  I looked  
at Ready Driver Plus, which seemed to work, but was only a  
workaround.  It also seemed to kill my terminal connection from Dom0.   
After some research, I found another way:

Which will disable driver signature enforcement.  Also, it's  
reversible too.  Here's a breakdown of what I did:
- started with clean install of Windows Server 2008 Enterprise (64-bit)
- installed latest GplPV drivers, verified everything was working with  
the driver enforcement enabled at each boot
- as per DSEO instructions, disabled all User Account Controls via  
windows secpol.msc snap-in
- installed DSEO and enabled test mode
- reboot
- GplPV drivers came up disabled, so I reinstalled the GplPV drivers,  
then ran DSEO and test singed each xen file under C:\Windows 
\system32\drivers which was about 4 files total
- reboot
- OS booted up without prompting for driver enforcement override
- re-enabled the User Account Controls, and rebooted to verify that  
everything was still working
I'd be curious to know if this works or not for anyone else.  For now,  
I'm moving on to do more tests on my windows DomU, and hoping that I  
can put the driver enforcement issue behind me.
