Xen project Mailing List

No, sorry, possibly I was unclear

A self-signed certificate is the same as a test signed cert â and youâll need to have test signing turned on.

But if you have a certificate signed by verisign (or similar), you can use that to sign the code and avoid needing to turn test signing on.

I donât know of any problems with the PV drivers and windows 10 (There were with Citrix / XenServer drivers, but the drivers in recent hotfixes have fixed those problems)

I'm very grateful to your help.

So if I have a self signed certificate and import it to Windows's Trusted Root CA in the certificate store, I can properly install self compiled PV drivers signed by that certificate to that Windows guest. Is my understanding correct?

I saw a lot mails in this mailing list discussing failure of PV drivers working under Windows 10. Does it mean the PV drivers are not yet stable enough to work under Windows 10?

Those statements are correct.

The drivers provided by Citrix XenServer are from the same code base as the Xen project PV drivers â but are currently older (and taken from a point before the drivers were handed over from the XenServer project to the Xen project). Those drivers have BSD licensed source code (as do the Xen project drivers) so there shouldnât be a conflict (but donât trust me â Iâm not a lawyer and not speaking for Citrix here)

I would expect the Citrix drivers to work with Xen (but no promises, YMMV!). And going forwards (as Citrix PV drivers are increasingly built from Xen project rather then the XenServer project code) this will be more and more likely.

(incidentally, if you have a code signing cert with a chain of trust back to a root provider, you can sign any drivers you build â and then install those certificates into Windows â avoiding worrying about needing to turn test signing on. Not sure if that helps)

I've asked the questions at the Xen users mailing list but nobody has interest to offer me a help. If the questions are too basic and should not be raised in this devel mailing list, please forgive me.

I want to install a signed PV drivers in my HVM windows guest since I learnt from the web that a test signed driver may lead to conflicts with some Windows applications.

I studied a lot from the Xen project pages and Xen mailing list for users and pv driver development. I am confused since some of the information seems to be out-dated.

I consolidated what I learnt so far and would like to seek for help to clarify the following conecpts before I make my next move:

1) Those signed Windows drivers resided on univention seemed to be already out-dated.

2) Those PV drivers provided on http://www.xenproject.org/developers/teams/windows-pv-drivers.html requires my own compilation. The drivers compiled are test signed and requires setting the Windows to test mode.

3) The PV drivers provided by Citrix XenServer seems to work also with Xen Hypervisor but I'm not sure whether there is any license conflict.

4) There are Microsoft signed PV drivers provided by Oracle VM but I need to use Oracle VM as my Domain 0 in order to use them.

Can anyone confirm my understanding as fore-mentioned?

I want to make a PC as a HTPC/NAS combo with HTPC part played by a Windows 7 (Windows 10 preferred if feasible) PV HVM guest.

I'm now stuck at the planning stage of Windows PV drivers. I don't want to compile anything and set the Windows to test mode.

So can I just download the PV drivers from Citrix and installed to the guest? Will it work with my Xen 4.5/4.6 Hypervisor with Ubuntu 15.04 Domain 0?

I'll be very grateful if anyone can help me.
