http://bugzilla.xensource.com/bugzilla/show_bug.cgi?id=413 Summary: Networking on guest domain not working Product: Xen Version: unstable Platform: All OS/Version: Linux Status: NEW Severity: critical Priority: P2 Component: Guest-OS AssignedTo: xen-bugs@xxxxxxxxxxxxxxxxxxx ReportedBy: dbarrera@xxxxxxxxxx The guest domain on an FC3 machine with today's build has a networking problem--t is unable to access the network. The guest domain cannot be accessed from the outside either, nor does it return a ping. This setup has worked reliably previously, so it is unlikely a setup issue. changeset: 7826:9bf6f907b3ff tag: tip user: kaf24@xxxxxxxxxxxxxxxxxxxx date: Wed Nov 16 04:29:52 2005 +0100 summary: Trivial coding style fix. I am curious as to why 'ifconfig -a' shows so many "veth's". The machine has only one NIC.
