Yes. The xen/evtchn and xen/gntdev are differently created on 2.6.32 and xen-4.0-testing. For details: http://lists.xensource.com/archives/html/xen-devel/2010-06/msg01129.html You can "fix" this by doing: git revert 376d908f52427591cef4acd172db9c3ef28676ec and git revert 9d85e25edbcb8a684db8470119077475ac4d90b5 That will make it possible for you to use the 2.6.32 with Xen 4.0 (and earlier versions). > > > 4) Anything else I should watch out for?

There is a patch that fixes some of the udev versions, but not all.
