make (almost) all links appear on only a single line, with no unnecessary whitespace, using double quotes for attributes. this lets us automatically convert them to markdown easily. the few remaining links are extremely long link in a gnome module, we'll come back to those at a later date.

A set of virtual proxy device labels with backing physical device ids.

Physical devices should already exist in <filename class="devicefile">/dev/input/by-id/</filename>.
|
|
Proxy devices will be automatically given a <literal>uinput-</literal> prefix.
|
|

See the <link xlink:href="https://github.com/aiberia/persistent-evdev#example-usage-with-libvirt">project page</link>

for example configuration of virtual devices with libvirt
|
|
and remember to add <literal>uinput-*</literal> devices to the qemu

<literal>cgroup_device_acl</literal> list (see <xref linkend="opt-virtualisation.libvirtd.qemu.verbatimConfig"/>).
