Directions for development & integration of Xen and QEMU
******
The Xen stack uses QEMU to provide a device model for HVM guests.
This results in a divergance of capabilities between paravirt and
fullyvirt guests & duplication of implementations. The pair of VNC
servers is one example. This talk will illustrate ways in which QEMU
can be used & extended to close the gap between HVM and paravirt
guests. It will also illustrate how to use QEMU to launch Xen guests
directly without any management tools.
