Libvirtd has long had integration with avahi for advertising libvirtd
using mDNS when TCP/TLS listening is enabled. For a long time the
virt-manager application had support for auto-detecting libvirtds
on the local network using mDNS, but this was removed last year

connect: Drop avahi support
Libvirtd can advertise itself over avahi. The feature is disabled by
default though and in practice I hear of no one actually using it
and frankly I don't think it's all that useful
The 'Open Connection' wizard has a disproportionate amount of code
devoted to this feature, but I don't think it's useful or worth
maintaining, so let's drop it
I've never heard of any other applications having support for using
mDNS to detect libvirtd instances. Though it is theoretically possible
something exists out there, it is clearly going to be a niche use case
in the virt ecosystem as a whole.
By removing avahi integration we can cut down the dependency chain for
the basic libvirtd install and reduce our code maint burden.

Libvirt is known to work as a client (not server) on Windows XP
|
|
(32-bit), and Windows 7 (64-bit). Other Windows variants likely work
|
|
as well but we either haven't tested or received reports for them.
|

|
|
<h2><a id="installer">Installation packages</a></h2>
|
|
|
|
<p>
|
|
Users who need pre-built Windows DLLs of libvirt are advised
|
|
to use the <a href="http://virt-manager.org">Virt Viewer</a>
|
|
pre-compiled <a href="http://virt-manager.org/download/">Windows MSI packages</a>
|
|
</p>
|
|
|
|
<p>
|
|
These installers include the libvirt, gtk-vnc and spice-gtk DLLs
|
|
along with any of their pre-requisite supporting DLLs, the virsh
|
|
command line tool and the virt-viewer & remote-viewer graphical
|
|
tools. The development headers are not currently provided in this
|
|
installer, so this cannot be used for compiling new applications
|
|
against libvirt.

<h2><a id="conntypes">Connection types</a></h2>
|
|
|
|
<p>
|
|
These connection types are known to work:
|
|
</p>
|
|
|
|
<ul>
|
|
<li>QEMU with TLS (qemu+tls://)</li>
|
|
<li>QEMU with direct TCP (qemu+tcp://)</li>
|
|
<li>VMware ESX (esx://)</li>
|
|
<li>VMware VPX (vpx://)</li>
|
|
</ul>
|
|
|
|
<p>
|
|
These connection types are known not to work:
|
|
</p>
|
|
|
|
<ul>
|
|
<li>QEMU with SSH (qemu+ssh://)</li>
|
|
</ul>
|
|
|
|
<p>
|
|
All other connection types may or may not work, and haven't been
|
|
tested.
|
|
</p>
|
|
|
|
<p>
|
|
Please let us know either the results (either way) if you do.

<b>Special note</b> - Support for VirtualBox *on windows* was added in
|
|
libvirt 0.8.7, so reports on success and failure if you're using that
|
|
would be really helpful and appreciated.
|
|
</p>
|
|
|
|
<p>
|
|
<b>WARNING - The qemu+tcp:// connection type passes all traffic
|
|
without encryption. This is a security hazard, and should <i>not</i>
|
|
be used in security sensitive environments.</b>

<h2><a id="tlscerts">TLS Certificates</a></h2>
|
|
|
|
<p>
|
|
TLS certificates need to have been created and placed in the correct
|
|
locations, before you will be able to connect to QEMU servers over
|
|
TLS.
|
|
</p>
|
|
|
|
<p>
|
|
Information on generating TLS certificates can be found here:

These instructions are for *nix, and have not yet been adapted for
|
|
Windows. You'll need to figure out the Windows equivalents until
|
|
that's done (sorry). If you can help us out with this, that would be
|
|
really welcome.
|
|
</p>
|
|
|
|
<p>
|
|
The locations of the TLS certificates and key file on Windows are hard
|
|
coded, rather than being configurable.
|
|
</p>
|
|
|
|
<p>
|
|
The Certificate Authority (CA) certificate file must be placed in:
|
|
</p>
|
|
|
|
<ul>
|
|
<li>%APPDATA%\libvirt\pki\CA\cacert.pem</li>
|
|
</ul>
|
|
|
|
<p>
|
|
The Client certificate file must be placed in:
|
|
</p>
|
|
|
|
<ul>
|
|
<li>%APPDATA%\libvirt\pki\libvirt\clientcert.pem</li>
|
|
</ul>
|
|
|
|
<p>
|
|
The Client key file must be placed in:
|
|
</p>
|
|
|
|
<ul>
|
|
<li>%APPDATA%\libvirt\pki\libvirt\private\clientkey.pem</li>
|
|
</ul>
|
|
|
|
<p>
|
|
On an example Windows 7 x64 system here, this resolves to these paths:
|
|
</p>
|
|
|
|
<ul>
|
|
<li>C:\Users\someuser\AppData\Roaming\libvirt\pki\CA\cacert.pem</li>
|
|
<li>C:\Users\someuser\AppData\Roaming\libvirt\pki\libvirt\clientcert.pem</li>
|
|
<li>C:\Users\someuser\AppData\Roaming\libvirt\pki\libvirt\private\clientkey.pem</li>

</ul>
