Xen users - Feb 2012 - Problem with Appletalk - Xen related ?

I have a system with Debian Squeeze & Xen 4.0

I installed Netatalk on a guest (also Debian Squeeze, PV) but atalkd 
won''t start - reporting "Can''t configure multicast".
If I install
Netatalk on Dom0 then it works - though being on the wrong machine 
it''s not very useful. I also tried installing on another guest - got 
the same results so it looks like it won''t run in a PV guest (or at 
least the PV guests I''m running).

Does anyone have any ideas ? Should the virtual NIC support this ?


atalkd is the Netatalk component that provides native AppleTalk 
protocol handling on the network - separate to the file & print 
services etc that can also run over IP.

I''m not experienced with atalkd, but did your kernel provides the same
IP and atalk features as in your Dom0 (i.e. IP multicast etc.)?

Did you use a bridged xen setup and is your bridge connected to the same
physical network as your Dom0. If not, could you try that?


best regards,


Niels.

Network is a standard linux bridge setup via Dom0 networking tools, 
one bridge, one NIC, one network. Both kernels are stock Debian 
Squeeze, same package :
linux-image-2.6.32-5-xen-amd64, 2.6.32-41

I''ve now dug out a spare machine, transferred the guest system to it, 
and made only the minimum changes (fstab etc) to make it boot as a 
physical standalone machine. It starts atalkd, and nbmlkup returns 
the results I''d expect on my network.

So I think I can be sure it''s not a software/config problem - the 
same image/setup works on a real machine but not as a PV guest under 
Xen.

Test machine is an AMD64 box, nVidia chipset, and forcedeth driver 
for the network. In the guest, "dmesg | grep eth0" doesn''t
show
anything - is that to be expected ?
