This patch extends the QEMU driver to support the <video> element for configuring the type of video adapter exposed to the guest. It implements the XML -> ARGV and ARGV -> XML conversions, so both import & export work. Some of the existing tests are updated to use the <video> element to get test coverage. The QEMU help parsing test is changed to use symbolic constants instead of black magic hex constants. This supports both old -std-vga and new -vga style QEMU args. Daniel From: Daniel P.
