Hallo xen-user, after compile and install src/xen-3.3.0 xenbr0 missing. Network to DomU works, but xenbr0 missing. Is xenbr0 no more needed? I need xenbr0 for the binding TAP for qemu on dom0. Whats going wrong? I accomplished some tests. Without result. regards Torsten ----------------------------------------------------------------- lati:~# ifconfig | grep "^[a-z]" eth0 Link encap:Ethernet HWaddr 00:15:C5:BE:8F:93 lo Link encap:Local Loopback peth0 Link encap:Ethernet HWaddr 00:15:C5:BE:8F:93 lati:~# ifconfig -a | grep "^[a-z]" eth0 Link encap:Ethernet HWaddr 00:15:C5:BE:8F:93 lo Link encap:Local Loopback peth0 Link encap:Ethernet HWaddr 00:15:C5:BE:8F:93 veth0 Link encap:Ethernet HWaddr 00:00:00:00:00:00 veth1 Link encap:Ethernet HWaddr 00:00:00:00:00:00 veth2 Link encap:Ethernet HWaddr 00:00:00:00:00:00 veth3 Link encap:Ethernet HWaddr 00:00:00:00:00:00 vif0.0 Link encap:Ethernet HWaddr FE:FF:FF:FF:FF:FF vif0.1 Link encap:Ethernet HWaddr FE:FF:FF:FF:FF:FF vif0.2 Link encap:Ethernet HWaddr FE:FF:FF:FF:FF:FF vif0.3 Link encap:Ethernet HWaddr FE:FF:FF:FF:FF:FF lati:~# xm create vm1 -c - network to vm1 works. but xenbr0 missing lati:~# brctl show bridge name bridge id STP enabled interfaces eth0 8000.0015c5be8f93 no peth0 vif1.0 vm1 # halt lati:~# ifconfig | grep "^[a-z]" eth0 Link encap:Ethernet HWaddr 00:15:C5:BE:8F:93 lo Link encap:Local Loopback peth0 Link encap:Ethernet HWaddr 00:15:C5:BE:8F:93 lati:~# ifconfig -a | grep "^[a-z]" eth0 Link encap:Ethernet HWaddr 00:15:C5:BE:8F:93 lo Link encap:Local Loopback peth0 Link encap:Ethernet HWaddr 00:15:C5:BE:8F:93 veth0 Link encap:Ethernet HWaddr 00:00:00:00:00:00 veth1 Link encap:Ethernet HWaddr 00:00:00:00:00:00 veth2 Link encap:Ethernet HWaddr 00:00:00:00:00:00 veth3 Link encap:Ethernet HWaddr 00:00:00:00:00:00 vif0.0 Link encap:Ethernet HWaddr FE:FF:FF:FF:FF:FF vif0.1 Link encap:Ethernet HWaddr FE:FF:FF:FF:FF:FF vif0.2 Link encap:Ethernet HWaddr FE:FF:FF:FF:FF:FF vif0.3 Link encap:Ethernet HWaddr FE:FF:FF:FF:FF:FF lati:~# brctl show bridge name bridge id STP enabled interfaces eth0 8000.0015c5be8f93 no peth0 lati:~# lati:/etc# egrep -v "^#| #" xen*/scripts/* | egrep "xenbr|tmpbridge" xen.old/scripts/network-bridge:bridge=${bridge:-xenbr${vifnum}} xen/scripts/network-bridge:tdev=tmpbridge xen/scripts/vif-bridge: if [ !
