Sorry.
By XenLinux I mean the Xen-aware Linux you're booting on top of Xen.

If you're only installing the tools, as I suggested, you only actually need to
do make tools; make install-tools, which should be much faster. If you just
do "make world" it'll build Xen and the XenLinux, which will take ages and
you already have those.
