Once i get the login prompt using the minimal ramdisk i run $ ifconfig eth0 up <eth0 mac address is what i assign in the config file> $ udhcpc Guest gets an IP address now. The above sequence doesn't work always but when it does get an IP address i can't ping domU or have it ping some other host. I didn't setup any firewall explicitly - just using plain ubuntu 13.04. I do see that the vif is added to the bridge. I also noticed that the errrors under eth0 starts going up when i create a guest and eventually the network in dom0 becomes completely unresponsive. root@arm:~# ifconfig eth0 Link encap:Ethernet HWaddr c6:e9:ba:c5:73:fe UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:637 errors:0 dropped:0 overruns:0 frame:0 TX packets:434 errors:180 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:56685 (56.6 KB) TX bytes:68582 (68.5 KB) lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 UP LOOPBACK RUNNING MTU:65536 Metric:1 RX packets:15 errors:0 dropped:0 overruns:0 frame:0 TX packets:15 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:1924 (1.9 KB) TX bytes:1924 (1.9 KB) vif4.0 Link encap:Ethernet HWaddr fe:ff:ff:ff:ff:ff UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:32 RX bytes:0 (0.0 B) TX bytes:0 (0.0 B) vif4.1 Link encap:Ethernet HWaddr fe:ff:ff:ff:ff:ff UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:32 RX bytes:0 (0.0 B) TX bytes:0 (0.0 B) xenbr0 Link encap:Ethernet HWaddr c6:e9:ba:c5:73:fe inet addr:192.168.1.159 Bcast:192.168.1.255 Mask:255.255.255.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:716 errors:0 dropped:0 overruns:0 frame:0 TX packets:535 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:83341 (83.3 KB) TX bytes:69860 (69.8 KB) root@arm:~# > What do you mean by "switching back to dom0"?
