- The <code>video</code> element is the container for describing
- video devices. For backwards compatibility, if no <code>video</code>
- is set but there is a <code>graphics</code> in domain xml, then libvirt
- will add a default <code>video</code> according to the guest type.
- For a guest of type "kvm", the default <code>video</code> for it is:
- <code>type</code> with value "cirrus", <code>vram</code> with value
- "9216", and <code>heads</code> with value "1". By default, the first
- video device in domain xml is the primary one, but the optional
- attribute <code>primary</code> (<span class="since">since 1.0.2</span>)
- with value 'yes' can be used to mark the primary in cases of multiple
- video device. The non-primary must be type of "qxl". The optional
- attribute <code>ram</code> (<span class="since">since
- 1.0.2</span>) is allowed for "qxl" type only and specifies
- the size of the primary bar, while <code>vram</code> specifies the
- secondary bar size. If "ram" or "vram" are not supplied a default
- value is used.
