I may be stating the obvious but that normally indicates the configure didn't work correctly. Does the kernel path your specifying have both the headers and a valid build tree?

Hi,

I am trying to set up the pvfs2 kernel module on a 3tera appliance
which is using a custom patched XenU kernel.

The kernel is based on the  2.6.18.8 kernel but with a lot of patches.

My problem is that when I run the "make kmod" command I get the
following errors:
[r...@apache1 pvfs-2.8.2]# make kmod
make -C /usr/src/redhat/BUILD/xen-3.3.2/linux-2.6.18-xen.hg
O=/usr/src/redhat/BUILD/xen-3.3.2/build-linux-2.6.18-xenU_x86_64
modules

Does anyone have any experience with pvfs2 on Xen?

Please help
