- Installing Windows 7 with IDE drivers require about 12 hours (qemu-kvm 0.12.5)
- Windows 7 can be installed with virtio disk (requires guest drivers during installation)
- Windows 7 64-bit requires signed drivers (available from August 2010 - thanks to RedHat)
- Installation with virtio drivers works well, but Windows will not reboot at the end.
Signed guest drivers are available here:
- Download the guest drivers
- Configure the virtual disk as virtio
- Start the installation
- When the installer asks you to select a drive, load the virtio driver (viostor)
- The installation should take 45 to 60 minutes
If you don't want to swap the CD, configure 2 CD-ROMs. Use the guest drivers as first CD-ROM, and Windows installation disk as second, else it won't boot.
Once installed, if you did choose virtio for the network card, you will also need to update the driver.
Cannot boot - broken MBR
At the final reboot, I get a screen telling
The libvirt log show
kvm: unhandled exit 80000021 kvm_run returned -22
The solution is to reinstall the MBR. Here is a very good tutorial for doing this: http://www.sevenforums.com/tutorials/20864-mbr-restore-windows-7-master-boot-record.html
