New subject: [PATCH 1 of 4] Add Password attribute to GraphicsRASD

# HG changeset patch # User Kaitlin Rupert <karupert@us.ibm.com> # Date 1247095850 25200 # Node ID f609e31b0c17ea550f27426dd8e329c362f4db3e # Parent 0fb4613252c19abb6bf5496a8b7031793ba7f298 Add Password attribute to GraphicsRASD Also add necessary changes to the graphics struct and generating XML with the passwd attribute. The passwd won't show up in the XML we get back from libvirt, so pulling the passwd from the guest XML isn't included in parse_graphics_device().
