Default Bug#582021: linux-image-2.6.32-bpo.4-xen-amd64 misses networking booting domUs installed via xen-tools

Hi,

it would be useful to know

sudo brctl show
sudo xm info
sudo xm list
lsmod
dpkg-query -W linux-image-$(uname -r)

on dom0 when you have no networking and

sudo ip link
lsmod
dpkg-query -W linux-image-$(uname -r)

on domU when you have no networking.

With squeeze dom0 and domU on amd64 at least

cat > config <<EOF
name = 'squeeze64'

bootloader = '/usr/bin/pygrub'

vcpus = '4'
memory = '512'

disk = [ 'file:/local/xen/squeeze64/disk.img,xvda,w' ]
vif = [ 'mac=00:01:01:99:7e:eb' ]
EOF
sudo xm create -c config

has networking.

In addition it would be very useful to try a much newer kernel. There
have been many changes to the pvops kernel patches between 2.6.32-11 and
now including a bunch of net{front,back} changes which may be related to
this problem.

Please can you also clarify which kernel is in use in domain 0 vs.
domain U.

Thanks,
Ian.

I wonder if this is simply down to the Lenny kernel having netfront
built static and the Squeeze backport kernel has it built as a module.

Perhaps combined with some failure to autoload the module for some
reason (bug in module-init-tools, something about the domU filesystem
configuration etc).

To confirm please add "xen-netfront" to /etc/modules inside the guest.

Thanks,
Ian.
