Ian,

Thanks!  I will role those in and send out a modified version later for 
comment.  If anyone else has items to add, please let me know.

>The use of "Xen Project" on this slide seems out of context/clumsy. If plain 
>"Xen" is not acceptable then perhaps "Xen Hypervisor"?

The problem here is the growing concern about proper use of trademark in 
externally-facing docs and presentations.  The guidance from Linux Foundation 
is to use "Xen Project" everywhere.  The old "Xen" mark is not owned by LF, 
and, hence, should not be used on the website, docs, and slides.  So even "Xen 
Hypervisor" is out of consideration.

Furthermore, since a trademark is an adjective, we shouldn't ever use "Xen 
Project" as a noun.  So, the former statement, "Now install Xen" becomes "Now 
install the Xen Project software" or something similar.   As graceful as 
snowshoes on a summer day, I know, but that's life in the big city.

Nothing major, but a few things I spotted:

"Improved Flexibility in Driver Domains"

        Another advantage is that things are now consistent between
        Linux and !Linux driver domains.
        
        IIRC it is also less racy (not risqÃ!) in various ways too.

"Experimental PVH Support"

        Clarify with "PVH Guest Support"? dom0 is pending for the next
        release IIRC.
        
        Say "reduced implementation footprint" perhaps? (trying to
        convey that the footprint in question is the amount of hacking
        around the guest's MM layer which is needed)
        
        Put a bullet "* Enable with pvh=1 in your config"? (likewise for
        each of these new things where such an option exists?)

"Tech Preview of Nested Virtualization"

        "provides... to *HVM* guests"

        The use of "Xen Project" on this slide seems out of
        context/clumsy. If plain "Xen" is not acceptable then perhaps
        "Xen Hypervisor"?

        Enable with "hap=1" and "nestedhvm=1"
        
"GRUB 2 Support of Xen Project PV Images"

        This is delivered by a grub release (I think it is in 2.02-beta,
        but 2.02 final isn't out yet)
        
        Not actually a Xen 4.4 feature. Not to say it isn't worth
        mentioning. AIUI it should work with older Xen too though.

"Improved ARM Support (2)"

        "Same DMA support". Should be "Some DMA Support" or "Sane..." or
        "Dom0 DMA support"? The implications of this stuff are that
        things work/don't crash ;-)
        
        on (3) The Allwinner processors are A20/A31 not A20/A30.

Ian.
