Xen users - Apr 2006 - XEN 3.0.1: domUs become zombies after shutdown with "unregister_netdevice: waiting for vifX.0 to become free. Usage count = n"

Hello guys

I have the following problem with xen 3.0.1 compiled from sources on 
Debian Sarge, kernel 2.6.12.6 which can be easily reproduced at least on 
my installation:
after I log in to domU console or via ssh and run "shutdown" I get 
deadlocked network interface with error message:

unregister_netdevice: waiting for vifX.0 to become free. Usage count = n

After this happen I can''t even reboot my dom0 via ssh because reboot 
process hangs (waits until interface is released but it never happens).

I googled about this error and found some references to bridged 
networking problem (yes I use bridged networking on my pc) but 
unfortunatelly I coudldn''t understand how to solve this problem.

Please could anyone help me to get out of it ?


About my config: I have both xen web server and xen relocation server 
disabled in config. I have a network with a few ip addresses and I want 
to assign address ie 192.168.0.1 to dom0 and then 192.168.0.x to my 
domUs so I think it can be only done using bridged networking.

Hello again

May be it would help somehow if I tell that I tried to apply "nousb" 
parameter to dom0 grub command line as described in FAQ and still get 
the same problem.
Altrough it not always happen when I do shutdown in domU.
I''m getting confused more and more :(

Hi everyone

I have solved my problem and want to share my expirience with others.
One should read xen networking manual 
(http://wiki.xensource.com/xenwiki/XenNetworking) and DON''T configure 
eth0 interface on domUs. eth interfaces are "connected virtual ethernet 
interfaces", they are preconfigured on kernel boot by xen itself.
