||
Overview
|
||
~~~~~~~~
|
||
|
||
This page describes how to obtain and use virtio drivers for Windows
|
||
virtual machines running on KVM, and additional software agents for
|
||
Windows VMs.
|
||
|
||
[[yumdnf-repo]]
|
||
Yum|Dnf Repo
|
||
~~~~~~~~~~~~
|
||
|
||
There is a yum|dnf repo shipping 'virtio-win' RPMs. The RPMs install
|
||
driver binaries and agent installers on your host machine into
|
||
/usr/share. 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`
|
||
|
||

|
||
If you previously used isos from alt.fedoraproject.org, note that these
|
||
new isos have a different file layout (matching RHEL isos). 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
|
||
~~~
|
||
|
||
[[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
