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

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/Installer.py 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

# cd ../RPMS/noarch
# yum reinstall python-virtinst-0.500.4-1.fc14.noarch.rpm

Now run virt-install :-

virt-install --connect qemu:///system --virt-type kvm \
--name W7VIRT64 --ram 4096 --disk path=/dev/vg_virtuals/vm01,bus=virtio \
--disk /usr/tmp/virtio-win-1.1.16.vfd,device=floppy \
--os-variant win7 \
--cdrom /usr/tmp/Win7_64.iso --vcpus 2
