This is a list of open work items and known bugs for the Xen on ARM with virtualization extension project.
In progress
- Xen 64-bit guests support: http://marc.info/?l=xen-devel&m=136310027317761 by Ian Campbell
 - Xen SMP: http://marc.info/?l=xen-devel&m=136256023123214 by Ian Campbell
 - Xen guest SMP support: http://marc.info/?l=xen-devel&m=136430925010828 by Stefano Stabellini
 - Linux SMP on Xen: http://marc.info/?l=linux-kernel&m=136430893610688&w=2 by Stefano Stabellini
 - trap WFI in Xen: http://marc.info/?l=xen-devel&m=136492132108133 by Stefano Stabellini
 - Remove hardcoded numbers and addresses in Xen, use device tree for everything. This enables a single Xen binary to boot on multiple platforms (Julien Grall).
