[Xen-users] Bridging configuration problem on Xen 3.0.3

["Ivan Lisenkov" <ivan@xxxxxxxxx>]

Dear All,

In my network configuration guests have ip addresses from one subnet and host from another.

All guests connected to dummy0 interface via bridge xenbr1, peth0 and vif0.0 are connected to xenbr0.

#brctl show
bridge name     bridge id               STP enabled     interfaces
virbr0          8000.000000000000       yes
xenbr0          8000.feffffffffff       no              peth0
                                                        vif0.0
xenbr1          8000.6e5d9a36604a       no              vif1.0
                                                        tap0
                                                        pdummy0
                                                        vif0.1

In this configuration domU can ping dom0 and vice-versa, but domU can't connect to the Internet.

If I add dummy0 to xenbr0 domUs see the Internet, but lost connection to dom0. In my case this is inapropriate.

What i should do to make packets routed properly?

Routing tables for Dom0:

# route -n
Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
94.75.##2.0     0.0.0.0         255.255.255.224 U     0      0        0 dummy0
94.75.##1.192   0.0.0.0         255.255.255.192 U     0      0        0 eth0
0.0.0.0         94.75.##1.254   0.0.0.0         UG    0      0        0 eth0

dummy0 has 94.75.##2.8  ip address, eth0 on dum0 has 94.75.##1.246 ip address.

For domU:

#route -n
Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
94.75.##2.0     0.0.0.0         255.255.255.224 U     0      0        0 eth0
0.0.0.0         94.75.##2.8     0.0.0.0         UG    0      0        0 eth0


Thank you for any help in advance!!!
