Yes, it has changed. There is memory hotplug feature under
development. Current fully working version is available at
git://git.kernel.org/pub/scm/linux/kernel/git/jeremy/xen.git
repository, xen/memory-hotplug head (Linux Kernel Ver. 2.6.34).
Patch for Linux Kernel Ver. 2.6.32.19 is available at
http://lists.xensource.com/archives/html/xen-devel/2010-08/msg00871.html
As I know memory hotplug is not working correctly with tmem now.
I am going to change that. Additionally, my goal is to include
memory hotplug support in mainline Linux Kernel.
If you have any questions please drop me a line.
Daniel
