We are waiting for a RHEL-6 z-stream update to fix an x11-xorg-server-Xorg bug which atm makes the mouse unusable in this mode wants this lands, multi-monitor support this way should be available for RHEL-6.2 (and later) guests. The same holds true for Fedora guests, although I don't expect the necessary Xorg changes to be available for versions older then Fedora 17. The driving multiple monitors from a single qxl device support OTOH is still a long time away, likely 6 months or so.

* WRT the native USB support, the wiki page says: "If the cluster level is 3.1 (which supports native USB support), but the client only has non-native USB support (old client), then we will use the old client. This means that we'll have to keep supporting the non-native USB support, side-by-side with the native one." Note that the new usb-support requires starting the guest with a number of extra emulated devices. These will just sit around and do nothing if unused, so I don't really expect any issues with this, but this still is something to be aware of. OTOH the old usb-support requires the installation of extra software inside the guest, if this is not installed falling back to the old client will not help wrt usb support.
