Hi Akio,
I was trying the same command as the second one you mentioned. But I
had moved the xen-3.1.0-src directory after compiling xen to some other
folder. On specifying the new path, make was still trying to access
files in the old path. Creating a symlink to the new path fixed the
problem :)
But I'm not able to load the module, dmesg gives an error: Unknown
symbol xenbus_write(). I have included xen/xenbus.h, do I need to do
anything in addition to that?
Regards,
Ashutosh

Did you use different vmlinuxs between dom0 and domU?
If using the same vmlinux, you can compile it on dom0 with the same way as linux.
For example, like the below.
"make -C /lib/modules/`uname -r`/build M=`pwd` V=1 modules"
If no, I think you should be able to use like the below.
"make -C /home/hoge/xen-unstable.hg/build-linux-2.6.18-xenU_ia64
M=`pwd` V=1
modules"
Best Regards,
Akio Takebe
