Pkg xen devel - Sep 2006 - Bug#388486: xen-utils-common: upgrade new 2.6.17-2-xen breaks create domU until modprobe netloop nloopbacks=n

Package: xen-utils-common
Version: 3.0+hg11292-2
Severity: normal


After a recent etch upgrade (2.6.17, xen-3.0.2) I was unable to "xm
create" until I
"modprobe netloop nloopbacks=10"

Error was network-bridge couln't create vif interface (backend not found).

brctl addbr ... fails because of no free netloop device.
passing more nloopbacks device to the module fixed the problem.

I use :
(network-script network-bridge)
(vif-script vif-bridge)

Maybe this occurs because of differents options to the kernel compilation.

I open this bug because it appens during a upgrade process

This is caused by the module netloop not being loaded. I had to manually
add it to /etc/modules for things to work.

Maybe network-bridge script should verify that this module is loaded or
the support enabled inside the kernel.
