Hi, My bridging stops when I start a third Xen domain !?!? I have a few domains setup (mail, wiki, pbx). If I start two domains bridge networking works great. But if I start a third, either the new domains does not work or one of the other DomUs stops working! By stop working I mean I can't route traffic outside of Dom0. I have been looking at this on and off for a couple of weeks. Any insight or things I should look at would be greatly appreciated. I don't want to bombard this email with 10,000 dumps. I will gladly post any information needed to figure this one out. Basic network is a 10.20.10.X network. Gateway is 10.20.10.1 Xen Dom0 IP is 10.20.10.125 Xen Mail domain is 10.20.10.150 Xen PBX domain is 10.20.10.152 Xen wiki domain is 10.20.10.153 [root@abc ~]# rpm -qa | grep xen kernel-xen-2.6.20-2925.13.fc7 kernel-xen-2.6.20-2936.fc7 xen-libs-3.1.0-6.fc7 xen-3.1.0-6.fc7 *************** Below.... 2 work fine ******************* [root@abc ~]# for i in wiki mail; do echo "# $i"; ssh $i arp; ssh $i "ping -c 4 4.2.2.2"; done # wiki Address HWtype HWaddress Flags Mask Iface 10.20.10.125 ether 00:19:B9:D7:FB:4B C eth0 10.20.10.199 ether 00:07:E9:82:60:33 C eth0 PING 4.2.2.2 (4.2.2.2) 56(84) bytes of data. >From 10.20.10.125: icmp_seq=1 Redirect Host(New nexthop: 10.20.10.1) 64 bytes from 4.2.2.2: icmp_seq=1 ttl=56 time=37.1 ms >From 10.20.10.125: icmp_seq=2 Redirect Host(New nexthop: 10.20.10.1) 64 bytes from 4.2.2.2: icmp_seq=2 ttl=56 time=32.3 ms 64 bytes from 4.2.2.2: icmp_seq=3 ttl=56 time=30.8 ms 64 bytes from 4.2.2.2: icmp_seq=4 ttl=56 time=29.9 ms --- 4.2.2.2 ping statistics --- 4 packets transmitted, 4 received, 0% packet loss, time 3000ms rtt min/avg/max/mdev = 29.954/32.570/37.142/2.781 ms # mail Address HWtype HWaddress Flags Mask Iface 10.20.10.125 ether 00:19:B9:D7:FB:4B C eth0 10.20.10.1 ether 00:14:1C:5D:B6:BB C eth0 PING 4.2.2.2 (4.2.2.2) 56(84) bytes of data. >From 10.20.10.125: icmp_seq=1 Redirect Host(New nexthop: 10.20.10.1) 64 bytes from 4.2.2.2: icmp_seq=1 ttl=56 time=38.1 ms 64 bytes from 4.2.2.2: icmp_seq=2 ttl=56 time=27.1 ms 64 bytes from 4.2.2.2: icmp_seq=3 ttl=56 time=31.3 ms 64 bytes from 4.2.2.2: icmp_seq=4 ttl=56 time=28.8 ms --- 4.2.2.2 ping statistics --- 4 packets transmitted, 4 received, 0% packet loss, time 3009ms rtt min/avg/max/mdev = 27.144/31.359/38.120/4.180 ms [root@abc ~]# ***************** Here we start the third xen domain, "pbx" ************ [root@abc ~]# xm start pbx [root@abc ~]# ***************** Initially WIKI works and PBX does not work ********* ***************** WAIT 5 MINUTES AND THE PBX WORKS, WIKI DOES NOT ******* [root@abc~]# for i in wiki mail pbx; do echo "# $i"; ssh $i arp; ssh $i "ping -c 4 4.2.2.2"; done # wiki Address HWtype HWaddress Flags Mask Iface 10.20.10.125 ether 00:19:B9:D7:FB:4B C eth0 10.20.10.1 ether 00:14:1C:5D:B6:BB C eth0 PING 4.2.2.2 (4.2.2.2) 56(84) bytes of data. --- 4.2.2.2 ping statistics --- 4 packets transmitted, 0 received, 100% packet loss, time 3008ms # mail Address HWtype HWaddress Flags Mask Iface 10.20.10.125 ether 00:19:B9:D7:FB:4B C eth0 10.20.10.1 ether 00:14:1C:5D:B6:BB C eth0 PING 4.2.2.2 (4.2.2.2) 56(84) bytes of data. >From 10.20.10.125: icmp_seq=1 Redirect Host(New nexthop: 10.20.10.1) 64 bytes from 4.2.2.2: icmp_seq=1 ttl=56 time=28.8 ms 64 bytes from 4.2.2.2: icmp_seq=2 ttl=56 time=30.3 ms 64 bytes from 4.2.2.2: icmp_seq=3 ttl=56 time=26.8 ms 64 bytes from 4.2.2.2: icmp_seq=4 ttl=56 time=26.7 ms --- 4.2.2.2 ping statistics --- 4 packets transmitted, 4 received, 0% packet loss, time 2997ms rtt min/avg/max/mdev = 26.794/28.220/30.383/1.513 ms # pbx Address HWtype HWaddress Flags Mask Iface 10.20.10.1 ether 00:14:1C:5D:B6:BB C eth0 10.20.10.125 ether 00:19:B9:D7:FB:4B C eth0 PING 4.2.2.2 (4.2.2.2) 56(84) bytes of data. >From 10.20.10.125: icmp_seq=1 Redirect Host(New nexthop: 10.20.10.1) 64 bytes from 4.2.2.2: icmp_seq=1 ttl=56 time=29.5 ms 64 bytes from 4.2.2.2: icmp_seq=2 ttl=56 time=27.9 ms 64 bytes from 4.2.2.2: icmp_seq=3 ttl=56 time=28.5 ms 64 bytes from 4.2.2.2: icmp_seq=4 ttl=56 time=33.1 ms --- 4.2.2.2 ping statistics --- 4 packets transmitted, 4 received, 0% packet loss, time 3002ms rtt min/avg/max/mdev = 27.900/29.783/33.102/2.006 ms [root@abc123~]# ********************************************* Thanks _______________________________________________ Xen-users mailing list Xen-users@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-users
