[Fedora-xen] PV network driver

Fri, 17 Aug 2007 08:24:29 -0700 

Hi,
as now i want to insert PV driver in my HVM guest to get better network 
performance, so i should run the following steps as from the README in file:
xen-3.0.3-8.fc6.src.rpm_FILES/xen-3.0.3_0-src/unmodified_drivers/
---------------------------------------------------------------------
To build, run ./mkbuildtree and then
make -C /path/to/kernel/source M=$PWD modules

You get four modules, xen-evtchn-pci.ko, xenbus.ko, xen-vbd.ko, and
xen-vnif.ko.  Load xen-evtchn-pci first, then xenbus, and then
whichever of xen-vbd and xen-vnif you happen to need.
----------------------------------------------------------------------
after ./mkbuildtree the 'make' will bring following errors. where could be the 
problem?
