Virtio install Windows 7 KVM (x64/x86) on Fedora 14

January 25, 2011

Fedora 14 has version of Libvirt 0.8.7 and qemu-0.13.0-1 installed via Rawhide Preview Repo. However, straightforward attempt to virt-install Windows 7 on virtio boot device fails to detect device after viostor.sys gets preloaded. It’s a known bug [1]. Actually, thread at Red Hat Bugzilla – Bug 656353 contains required patch , but doesn’t contain any explanation how to rebuild and reinstall required package python-virtinst-0.500.4-1.fc14.noarch.rpm. Detailed workaround for this issue follows bellow as well as build of new package python-virtinst-0.500.5-1.fc14.noarch.rpm based on recent release virtinst 0.500.5 (Friday January 14, 2011)
Download and install python-virtinst-0.500.4-1.fc14.src.rpm. Apply patch bellow to /root/rpmbuild/SOURCES/virtinst-0.500.4/virtinst/ per Red Hat Bugzilla – Bug 656353 ( [1] ) and recreate /root/rpmbuild/SOURCES/virtinst-0.500.4.tar.gz. Then
# cd ../SPECS
# rpmbuild -bb ./python-virtinst.spec

Virtio install Windows 7 KVM (x64/x86) on Ubuntu 10.04.1 Server via DNJL PPA

January 20, 2011

First of all setup DNJL PPA to upgrade KVM/QEMU up to Qemu 0.12.5 & Libvirt 0.8.3 on Ubuntu Lucid Server and download the most recent Fedora virtio-win drivers from as floppy and ISO image. Notice , that same virt-install will run fine on KVM Server Ubuntu 10.10 due to required versions of Libvirt & Qemu appear to be installed by default.

Set up virtio network driver

Virtio install Windows 7 KVM (x64/x86) on Scientific Linux 6 (alpha 4)

January 11, 2011

Download and install virtio-win-1.1.16-0.el6.noarch.rpm via
Before starting install KVM make some changes to “Details”
1. Attach virtio-win-1.1.16.vfd as floppy.
2. Change type of boot up device to “Virtio”

Load virtio.sys driver from floppy to detect boot up device :-

Complete install as usual :-

Shutdown KVM , change type of bridge “br0” to “virtio” and attach CDROM virtio-win-1.1.16.iso to KVM. Then load KVM with broken Network , load “Device manager” and “Update driver for Ethernet Adapter” via attached RH CDROM

Set up RH VirtIO SCSI&Network drivers on Windows 7, Windows XP KVMs at KVM-QEMU Instance on F14

January 8, 2011

Create Windows KVM via virt-manager as usual. Download Latest VirtIO Win drivers from Fedora. Location is Notice also , that the last virtio-win-1.1.16-0.el6.noarch.rpm ( Last Redhat virtio signed windows driver ) been installed on Scientific Linux 6, allows to perform install Windows 7 KVM directly on “virtio” boot up device via loading drivers from virtio-win-1.1.16.vfd been attached as floppy to KVM before installation starts up. Virtio-win-1.1.16-0.el6.noarch.rpm may be downloaded in meantime at View for details
Virtio install Windows 7 KVM (x64/x86) on Scientific Linux 6 (alpha 4)
Download files virtio-win-1.1.11-0.vfd and ISO image virtio-win-1.1.11-0.iso to Fedora’s FS. Create fake qcow2 file :-

# cd /vms
# qemu-img create -f qcow2 fake.qcow2 1G

Procedure bellow is specific for 32-bit version of W7, 64-bit version requires KVM shut down (via my experience) to add fake.qcow2 disk and virtio-win-1.1.16.iso as CDROM. Then load KVM and Update broken SCSI driver ( “Device Manager”) via attached CD.
Start Windows KVM and switch to “Details”
1. Attach virtio-win-1.1.11-0.iso as CDROM to KVM
2. Add fake.qcow2 as “virtio” disk

Now switch to “Console” . “Add New Hardware” Wizard should be already up and running. Install required driver from attached

Shutdown Windows KVM . Remove fake qcow2 disk and change type Windows boot up disk to “Virtio”

Start up Windows KVM and make sure driver has been properly installed

Same procedure works for 32-bit version Windows 7 KVM

Shutdown Windows 7 KVM . Remove fake disk and switch type of boot up device to “Virtio”

Boot up Windows 7 KVM again and make sure RH VirtIO SCSI Driver has been properly installed

To install RH Virtio Ehernet Adapter via same CDROM :
1. Change bridge type “br0” to “Virtio”
2. Start KVM with broken network
3. Go to “Control Panel=>Devices Management
4. Update Network driver via Fedora’s CDROM attached
