I am in a position to test NetBSD HEAD and Xen 4.0 on quite a few
hardware configurations and I have a few questions


Was the above compile issue ever resolved?
now that Xen 4.0 is released (4-7-2010) are there newer Xen 4.0
patches somewhere?

reading the New Feature list for Xen 4.0 Here
http://wiki.xensource.com/xenwiki/Xen4.0

Could someone give a quick review of any Fetaures that are in Xen 3.x
/ 4.x that are not present in NetBSD
assuming using NetBSD HEAD amd64 as the dom0



Thank you for any help
