Can you try 3.0.4 domU kernel agaianst 3.1 dom0 kernel, and vice versa? Also, turn on debug tracing in Xen (boot options ‘loglvl=all guest_loglvl=all’) and see what appears at the end of ‘xm dmesg’.

At the same time in dom0, we see the following error message in /var/log/messages:

"vif vif-16-3: 1 mapping shared-frames 2310/2311 port 11"

(the error message above means that netif_map failed for some reason in XenBus)



If we repeat this same exact test using XEN 3.0.4, we never have any problems. All vifs in all VMs work correctly. This problem must be specific to XEN 3.1.
