Assuming a hypervisor that supports multiple smartcard devices in the
guest, this would be a valid XML description:
<devices>
<smartcard mode='host'/>
<smartcard mode='host-certificates'>
<certificate>/path/to/cert1</certificate>
<certificate>/path/to/cert2</certificate>
<certificate>/path/to/cert3</certificate>
</smartcard>
<smartcard mode='passthrough' type='tcp'>
<source mode='connect' host='127.0.0.1' service='2001'/>
<protocol type='raw'/>
</smartcard>
</devices>
* docs/formatdomain.html.in (Smartcard devices): New section.
* docs/schemas/domain.rng (smartcard): New define, used in
devices.
* tests/qemuxml2argvdata/qemuxml2argv-smartcard-host.xml: New file
to test schema.
* tests/qemuxml2argvdata/qemuxml2argv-smartcard-host-certificates.xml:
Likewise.
* tests/qemuxml2argvdata/qemuxml2argv-smartcard-passthrough-tcp.xml:
Likewise.

+ <h4><a name="elementsSmartcard">Smartcard devices</a></h4>
+
+ <p>
+ A virtual smartcard device can be supplied to the guest via the
+ <code>smartcard</code> element. A USB smartcard reader device on
+ the host cannot be used on a guest with simple device
+ passthrough, since it will then not be available on the host,
+ possibly locking the host computer when it is "removed".
+ Therefore, some hypervisors provide a specialized virtual device
+ that can present a smartcard interface to the guest, with
+ several modes for describing how credentials are obtained from
+ the host or even a from a channel created to a third-party
+ smartcard provider. <span class="since">Since 0.8.8</span>
+ </p>
+
+<pre>
+ ...
+ <devices>
+ <smartcard mode='host'/>
+ <smartcard mode='host-certificates'>
+ <certificate>/path/to/cert1</certificate>
+ <certificate>/path/to/cert2</certificate>
+ <certificate>/path/to/cert3</certificate>
+ </smartcard>
+ <smartcard mode='passthrough' type='tcp'>
+ <source mode='connect' host='127.0.0.1' service='2001'/>
+ <protocol type='raw'/>
+ </smartcard>
+ </devices>
+ ...
+</pre>
+
+ <p>
+ The <code><smartcard></code> element has a mandatory
+ attribute <code>mode</code>. The following modes are supported;
+ in each mode, the guest sees a device on its USB bus that
+ behaves like a physical USB CCID (Chip/Smart Card Interface
+ Device) card.
+ </p>
+
+ <ul>
+ <li><code>mode='host'</code> — the simplest operation,
+ where the hypervisor relays all requests from the guest into
+ direct access to the host's smartcard via NSS. No other
+ attributes or sub-elements are required.</li>
+
+ <li><code>mode='host-certificates'</code> — rather than
+ requiring a smartcard to be plugged into the host, it is
+ possible to provide three files residing on the host and
+ containing NSS certificates. These certificates can be
+ generated via the command <code>certutil -d /etc/pki/nssdb -x -t
+ CT,CT,CT -S -s CN=cert1 -n cert1</code>, and the resulting three
+ files must be supplied as the content of each of
+ three <code><certificate></code> sub-elements.</li>
+
+ <li><code>mode='passthrough'</code> — rather than having
+ the hypervisor directly communicate with the host, it is
+ possible to tunnel all requests through a secondary character
+ device to a third-party provider (which may in turn be talking
+ to a smartcard or using three certificate files). In this mode
+ of operation, an additional attribute <code>type</code>,
+ matching one of the supported <a href="#elementsConsole">serial
+ devices</a>, to describe the host side of the tunnel; if
+ omitted, <code>type='tcp'</code> is assumed. Further
+ sub-elements, such as <code><source></code>, are required
+ according to the given type, although
+ a <code><target></code> sub-element is not required (since
+ the consumer of the character device is the hypervisor itself,
+ rather than a device visible in the guest).</li>
+ </ul>
