I am building Xen-3.2.0 (from source) with a 'working, known good' xenified linux kernel from Fedora Core 8 (kernel-xen-2.6.21.7-3.fc8xen).
Here is the build failure I get when I run:
# make prep-kernels KERNELS="linux-2.6-xen0 linux-2.6-xenU"
which succeeds.
# make dist KERNELS="linux-2.6-xen0 linux-2.6-xenU"
which almost completes the build but at the end result in the below build error:
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

Now, according to that other discussion thread, (back in Sept-2007) the solution was to get the latest linux-2.6.18 from the mercurial repository (although the root cause or fix
was not clearly discussed). Since I am using a xenified Fedora core kernel-xen source tree of my own, I would like to know the cause and possible fix for this.
My guess: It seems like the target linux bulid directory build-linux-2.6.18-xen0_x86_32, the sub-directory /arch/i386/boot/ is not getting created for some reason. Should the 'make dist' also specify XEN_TARGET_ARCH=x86_32 ?
Note: I am able to successfully build the linux kernel from the original kernel source directory without any such errors. Only 'make dist' fails.
-regards,
