[libvirt] [PATCH 0/4] Support for SPICE graphics

This series of patches adds minimal support for SPICE graphics which is newly introduced in RHEL-5.4's fork of KVM. Since this is not yet merged in upstream QEMU/KVM, I'm not proposing to merge all these patches. The two XML schema patches are straightforward to merge. The two implementation ones are RHEL5 specific and I want to avoid declaring them supported until we have a sign of what the upstream merge will look like, since previous attempst to support KVM args prior to QEMU acceptance have been very painful long term.
