Re: [Libguestfs] Attempts to install a Windows driver from WinPE

An update on this as promised: I have now made it work with Windows 2008 R2! The short version: 1. Create a Windows PE image containing VirtIO drivers * Install WAIK for Windows 7 on your build system * Create a stock amd64 Windows PE image * Use DISM to mount the image * Use DISM to install the amd64 viostor driver for Win2008 in the image * Use DISM to unmount the image * Copy the image to sources\boot.wim in the ISO tree * Copy the complete contents of the virtio driver floppy into ISO tree * Create a bootable ISO image from the ISO tree 2. Use Windows PE image to install driver in guest * Ensure guest is configured to use VirtIO for storage * Add Windows PE image as boot image for guest * Boot guest with Windows PE image Guest system drive is D: Mounted ISO image is E: * Run: dism /image:d:\ /add-driver /driver:e:\virtio\amd64\win2008\viostor.inf * exit * Configure guest to boot from HD The guest will now boot normally using VirtIO. The biggest gotcha in the above is that if you google 'WAIK' it will send you to a download page for Windows Automated Installation Kit. Unless you're extremely eagle-eyed (I wasn't) you won't notice that this was released in 2007, and it doesn't support Windows 2008 R2. However, if you search for WAIK in the search box (not the Bing one, the useful one below that), you'll find it. DISM is new in the latest WAIK. Compared to pkgmgr it's a doddle to install a driver as you don't need an obtuse unattend.xml. I'm about to test the same image against 32bit Windows 2003. I'll report back on how that goes.
