These bits can then be shared with Windows VMs. Install the repo file: `sudo wget `https://fedorapeople.org/groups/virt/virtio-win/virtio-win.repo[`https://fedorapeople.org/groups/virt/virtio-win/virtio-win.repo`]` -O /etc/yum.repos.d/virtio-win.repo` Then install the virtio-win package with link:dnf[DNF] or YUM: `sudo dnf install virtio-win` + `sudo yum install virtio-win` The .repo file provides two different repositories: * virtio-win-stable ** This provides builds of virtio-win that roughly correlates to what was shipped with the most recent RHEL release, meaning they have received a decent chunk of testing. ** This repo is enabled by default. * virtio-win-latest ** This provides the latest driver builds. They may be development quality, or bug free, or complete broken. Caveat emptor :) ** This repo is disabled by default. If you want to update from virtio-win-stable to the latest bits, do: `sudo yum --enablerepo=virtio-win-latest update virtio-win` or with dnf: `sudo dnf --enablerepo=virtio-win-latest upgrade virtio-win` [[rpm-contents]] RPM contents ^^^^^^^^^^^^ * /usr/share/virtio-win/*.iso: ISO CDROM containing all the drivers.

If you need to access the old isos you can do so https://fedorapeople.org/groups/virt/virtio-win/deprecated-isos/[here]. However these isos are deprecated and only kept around for back compatability. No new isos will be added there. [[faq]] FAQ ~~~ [[what-license-are-these-drivers]] What license are these drivers? ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ The drivers are licensed under the GPLv2. [[why-arent-the-drivers-shipped-as-part-of-fedora]] Why aren't the drivers shipped as part of Fedora? ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ The drivers cannot be shipped as part of Fedora because they can't be built in Fedora's build system; the only way to build the drivers is on a Windows machine. Shipping pre-compiled sources is generally against Fedora policies. There's likely other objections as well. [[where-do-the-builds-come-from]] Where do the builds come from? ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ All the windows binaries are scooped up from builds done on Red Hat's internal build system, which are generated using publicly available code. See the README in this repo for some more details about how the RPM and repo are built: https://github.com/crobinso/virtio-win-pkg-scripts [[what-is-the-reasoning-behind-the-rpmiso-layout]] What is the reasoning behind the RPM/ISO layout? ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ For starters, the primary purpose of the RPM/ISO is to mirror exactly the layout that is shipped with the latest RHEL release. This is so user/developers don't have to deal with differences between the two distros. (Note: Historically the .iso files shipped on alt.fedoraproject.org did _not_ match the layout of the .iso shipped in RHEL. This changed in April 2015) * The .iso directories are named after the driver code directories from the upstream driver git tree. There isn't much more to it than that. * Below the driver directories, the $winversion/$arch/ directory naming is a windows convention. * The RPM layout is kind of arbitrary in that it ships the .vfd content in the drivers/ dir, but not many of the other drivers from the .iso. This seems to be an historical oversight and should probably be fixed. [[are-these-drivers-signed]] Are these drivers signed? ^^^^^^^^^^^^^^^^^^^^^^^^^ These drivers are cryptographically signed with Red Hat's vendor signature. However they are not signed with https://msdn.microsoft.com/en-us/library/windows/hardware/ff553976%28v=vs.85%29.aspx[Microsoft's WHQL signature]. [[how-are-these-drivers-different-from-what-is-shipped-with-rhel]] How are these drivers different from what is shipped with RHEL? ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ The RPMs from the stable repository are the same driver builds as what is shipped in RHEL. However, the public drivers are not signed with https://msdn.microsoft.com/en-us/library/windows/hardware/ff553976%28v=vs.85%29.aspx[Microsoft's WHQL signature]. [[how-does-lack-of-whql-signature-affect-use-of-these-drivers]] How does lack of WHQL signature affect use of these drivers? ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ FIXME: Lack of WHQL signature causes windows to complain, need to explicitly document how [[bugs]] Bugs ~~~~ Please file any bug reports against https://bugzilla.redhat.com/enter_bug.cgi?product=Virtualization%20Tools&component=virtio-win[Product=Virtualization Tools Component=virtio-win] When filing a bug, please provide the following info: * The virtio-win version * The host distro * The qemu version * If using libvirt: sudo virsh dumpxml $vmname * The qemu command line.
