Thread-topic: [Xen-devel] Networking in Xen

Can you send the "brctl show" output and also the config file for the domu creation Thanks -Padma -----Original Message----- From: xen-devel-bounces@xxxxxxxxxxxxxxxxxxx [mailto:xen-devel-bounces@xxxxxxxxxxxxxxxxxxx] On Behalf Of Girish V Sent: Tuesday, May 06, 2008 8:50 AM To: xen-devel@xxxxxxxxxxxxxxxxxxx Subject: [Xen-devel] Networking in Xen Hello, I have computer which is not connected to the internet (its eth0 is assigned 10.10.0.13 statically and is UP). I am running Xen 3.0.2 on it. I want my domU to be able to ping the dom0 and vice versa (I am assigning 10.10.0.14 to the domU). I tried a bridged connection, but when I tried to ping 10.10.0.13 from the domU I get the message "connect: Network is unreachable". When I pinged the domU from dom0 I got "Destination Host Unreachable" What sort of a networking should I set up to achieve this? (I have shown ifconfig, route and iptabes below). Any help is appreciated Thanks, Girish my ifconfig from dom0 looks like ---------------------------------------------------- eth0 Link encap:Ethernet HWaddr 10:10:10:10:10:26 inet addr:10.10.0.13 Bcast:0.0.0.0 Mask:255.255.255.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:26 errors:0 dropped:0 overruns:0 frame:0 TX packets:12 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:2270 (2.2 KiB) TX bytes:1468 (1.4 KiB) lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 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:0 RX bytes:0 (0.0 KiB) TX bytes:0 (0.0 KiB) peth0 Link encap:Ethernet HWaddr FE:FF:FF:FF:FF:FF inet6 addr: fe80::fcff:ffff:feff:ffff/64 Scope:Link UP BROADCAST RUNNING NOARP MTU:1500 Metric:1 RX packets:15 errors:2 dropped:0 overruns:0 frame:0 TX packets:41 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:2483 (2.4 KiB) TX bytes:4137 (4.0 KiB) Interrupt:10Base address:0x3080 vif0.0 Link encap:Ethernet HWaddr FE:FF:FF:FF:FF:FF inet6 addr: fe80::fcff:ffff:feff:ffff/64 Scope:Link UP BROADCAST RUNNING NOARP MTU:1500 Metric:1 RX packets:12 errors:0 dropped:0 overruns:0 frame:0 TX packets:31 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:1468 (1.4 KiB) TX bytes:2668 (2.6 KiB) vif2.0 Link encap:Ethernet HWaddr FE:FF:FF:FF:FF:FF inet6 addr: fe80::fcff:ffff:feff:ffff/64 Scope:Link UP BROADCAST RUNNING NOARP MTU:1500 Metric:1 RX packets:15 errors:0 dropped:0 overruns:0 frame:0 TX packets:1 errors:0 dropped:203 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:846 (846.0 b) TX bytes:42 (42.0 b) xenbr0 Link encap:Ethernet HWaddr FE:FF:FF:FF:FF:FF inet6 addr: fe80::200:ff:fe00:0/64 Scope:Link UP BROADCAST RUNNING NOARP MTU:1500 Metric:1 RX packets:208 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:860 (860.0 b) TX bytes:468 (468.0 b) --------------------------------------------------------------------- route on dom0 shows ----------------------------------------------------------------------- Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 10.10.0.0 * 255.255.255.0 U 0 0 0 eth0 default 10.10.0.1 0.0.0.0 UG 0 0 0 eth0 ------------------------------------------------------------------------ - iptables -L on dom0 shows --------------------------------------------------------------------- Chain INPUT (policy ACCEPT) target prot opt source destination Chain FORWARD (policy ACCEPT) target prot opt source destination ACCEPT all -- 10.10.0.13 anywhere PHYSDEV match --physdev-in vif2.0 ACCEPT udp -- anywhere anywhere PHYSDEV match --physdev-in vif2.0 udp spt:bootpc dpt:bootps Chain OUTPUT (policy ACCEPT) target prot opt source destination --------------------------------------------------------------------- ifconfig on domU shows --------------------------------------------------------------------- eth0 Link encap:Ethernet HWaddr 00:16:3E:3D:D5:18 inet addr:10.10.0.14 Bcast:10.10.0..255 Mask:255.255.255.0 inet6 addr: fe80::216:3eff:fe3d:d518/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:1 errors:0 dropped:0 overruns:0 frame:0 TX packets:15 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:42 (42.0 b) TX bytes:846 (846.0 b) lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:108 errors:0 dropped:0 overruns:0 frame:0 TX packets:108 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:7884 (7.6 KiB) TX bytes:7884 (7.6 KiB) --------------------------------------------------------------------- route on domU shows ----------------------------------------------------------------------- Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 10.10.10.0 * 255.255.255.0 U 0 0 0 eth0 169.254.0.0 * 255.255.0.0 U 0 0 0 eth0 ------------------------------------------------------------------------ - _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel
