Al in all this looks good, some remarks:
* WRT multi monitor support for RHEL, the latest RHEL
xorg-x11-drv-qxl and
spice-vdagent packages do support multi monitor support using
multiple
cards in Xinerama mode. 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.
The idea behind this support is to have it on a single PCI card, and not on
multiple ones.
* 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.
Of course. Added a note on that in the wiki page.
Thank you,
Oved
