Yes, before you install the new xen, do a make uninstall and rebuild the
new source.  Beware that it removes all xen related files from your boot
directory. So make a backup of all the xen-syms, xen-kernels from the
directory you boot from.

It still doesn't work.
I made a clean install of Xen 3.0.3, and it doesn't work if I want to have more than 4 bridge devices:


Link veth4 is missing. This may be because you have reached the limit of the number of interfaces that the loopback driver supports. (...)


# dmesg|grep loop
loop: loaded (max 8 devices)


When I uninstall Xen 3.0.3, and install Xen 3.0.2, I don't have this problem anymore.
Uninstall Xen 3.0.2 and install 3.0.3 - problem comes back.

So I guess something's borked in Xen 3.0.3.
