I cannot uncomment upstream.core.patches and the xen.pvhvm.patch
it gives failed HUNKs

> Ok, they are.. v2.6.37-rc2 which came out today has the fixes

I am pretty sure rc2 doesn't contain everything from xen.next-2.6.37.patch,
gntdev's stuff for sure. I've built 2.6.37-rc2 kernel rpms and loaded
kernel-2.6.27-rc2.git0.xendom0.x86_64 under Xen 4.0.1.
Device /dev/xen/gntdev has not been created. I understand that it's
unrelated to DomU ( related to Dom0) , but once again with rc2 in DomU i cannot
get 3.2 GB copied over to DomU from NFS share at Dom0.
The best results for 2.6.37-rc1 + xen.next-2.6.37.patch + xen.pcifront.fixes.patch

Boris.

Huh. I .. what? I am confused. I thought we established that the issue
was not related to Xen PCI front? You also seem to uncomment the
upstream.core.patches and the xen.pvhvm.patch - why?

Ok, they are.. v2.6.37-rc2 which came out today has the fixes.
