Red Hat Bugzilla – Bug 532480
libvirt lacks of signed drivers for virtio and viostor
Last modified: 2010-03-16 13:24:56 EDT
Description of problem: New version of windows allows only signed drivers to be loaded on install and refuses to install self build or http://sourceforge.net/projects/kvm/files/kvm-driver-disc/20080318/kvm-driver-disc-20080318.iso/download Version-Release number of selected component (if applicable): libvirt0 0.4.6-10 How reproducible: install from en_windows_7_enterprise_x64_dvd_x15-70749.iso image using <disk type='file' device='disk'> <source file='hda.img'/> <target dev='hda' bus='virtio'/> </disk> Actual results: Windows can't load driver during install Expected results: Windows can load driver during install, and recognizes target disk.
This is not a libvirt bug - its not libvirt's responsibility to provide guest drivers. The URL you grabbed is the old drivers though. The new KVM Win32 drivers are WHQL'd and available from this site: http://www.linux-kvm.org/page/WindowsGuestDrivers
You stating that this isn't libvirt bug. So this means that libvirt will not support windows guest. And there isn't such plan? This is important to community/busines to know about such plans. In this case community can chose other products/alternatives. I tried suggested your link and still having trouble: http://www.linux-kvm.org/page/WindowsGuestDrivers -> Download binary drivers http://www.linux-kvm.org/page/WindowsGuestDrivers/Download_Drivers -> Storage drivers http://people.redhat.com/~yvugenfi/24.09.2009/viostor.zip c8ce35f4b887e8a71e1cf8e4237fd25f viostor.zip copied only Install/Vista_Win2008_Win7 to floppy image after boot tried to load drivers (image:screen.png) and getting this error (image:screen2.png). May be wrong driver? May be thease drivers arn't WHQL'd? may be WHQL isn't enought?

What it means is that libvirt is not involved with the guest virtio drivers. Libvirt sets up the qemu backends for the guest; it's up to the guest to have drivers to drive the hardware that qemu presents to it. > > This is important to community/busines to know about such plans.

Your best bet is to post to the kvm mailing list (kvm@vger.kernel.org) with details of what your problem is. The developers of the Windows drivers read that list and can help you get started.

according http://marc.info/?l=kvm&m=125727943113418&w=4 kvm states that they don't have plans to provide signed drivers. Can i reopen this bug?

No. It has nothing at all to do with libvirt, so it doesn't even make sense. It only has to do with the drivers inside the Windows guest. If you need signed drivers, you have a few options: 1) Convince upstream virtio-win to get the drivers signed. 2) Open a Fedora bug to ask for signed Windows virtio drivers. This would be against the virtio-win component, not libvirt. 3) Buy a Red Hat subscription to get signed drivers Again, this is not a libvirt bug, this is strictly a virtio Windows driver issue.
