[Xen-users] No traffic between tap* and vif*

[Bert Sluijer <a.j.sluijer@xxxxx>]

Newbie-question:

After a big hassle trying to configure ubuntu-xen-server on 7.10, I installed xen-3.2-testing.hg with linux-2.6.18-xen.hg on ubuntu-7.10 . All things went fine and I got a stable virtualization platform, without kernel-errors. I started the w2k03-servers but they had no network. All 3 had a 169.x.x.x ipaddress and could communicate between themselves but not with the internet. Ifconfig on the host showed I had now 3 tap*-interfaces and als 3 vif*-interfaces. I learned from tcpdump that there seems to be no communication between tap* and vif*.

I think I overlooked something on the interface configuration of the host. 

brctl show:

bridge name     bridge id               STP enabled     interfaces
eth0            8000.001e0b701252       no              peth0
                                                        vif1.0
xenbr0          8000.12f74675b5eb       no              tap0
                                                        vif3.0
                                                        tap2
                                                        vif4.0
                                                        vif8.0
                                                        tap3

vif1.0 is a linux-guest which has connection to the internet. Looking for clues!

Thanks,

Bert.
