http://bugzilla.xensource.com/bugzilla/show_bug.cgi?id=1240 Summary: Incorrect veth0 interface on reboot Product: Xen Version: 3.0.3 Platform: x86 OS/Version: Windows Status: NEW Severity: normal Priority: P2 Component: Unspecified AssignedTo: xen-bugs@xxxxxxxxxxxxxxxxxxx ReportedBy: drak@xxxxxxxxxxxx I think I may have encoutered a bug in Xen. I am using Xen as suplied by RHEL5. On this particular machine after a reboot I get an interface veth0 which has all the same ip settings as eth0. In this state no Xen instances hosted on this machine are accessible to the network. After a "service xend restart" the veth0 interface disappears and my Xen instances can see the network. I narrowed it down a little and found if I execute the following (from a screen to avoid my SSH connection dropping) then it also removes this duff interface. cd /etc/xen/scripts ./network-bridge stop;./network-bridge start When I reboot the machine, the misconfigured interface returns. I then found that this condition only seems to occur when I have extra IP addresses mounted on eth0 on interfaces eth0:1 and eth0:2 - if I remove them from the server config, then when I reboot the server I dont get veth0 at all. I guess there is a bug with the briding startup scripts? Here is an ifconfig -a output on reboot -------- START eth0 Link encap:Ethernet HWaddr 00:E0:81:43:9C:F6 inet addr:38.99.95.229 Bcast:38.99.95.255 Mask:255.255.255.128 UP BROADCAST RUNNING MULTICAST
