Hi, I get this strange error about string and nonetype concatenating, but
I think I am not sure why it is complaining at having a Nonetype
somewhere, as if I did not define some configuration option? I use the
following command (below that, there is a dry-run
result):
FYI: I removed the loopback.o from the drivers/xen/netback/Makefile and
recompiled the whole thing. This was because Xen unstable did not work,
some strange behaviour with arp. Now it does work, the veth0 interface and
the network.
