I thought I would try xen again, the last time I could not get Dom0 connected
to the router and gave up. The network documentation in the wiki seems to
imply that the ifconfig/route comands for eth0 remain the same, although eth0
is now a virtual device. After booting dom0 and starting xend, netstat gave
the usual output but I was unable to ping my router. Stopping iptables had no
effect. Looking again at the wiki article, I found a link to a thread
(http://lists.xensource.com/archives/html/xen-devel/2005-01/msg00425.html)
that implied you had change the IP definitions to use interface xen-br0. Am I
reading this right? If not, what changes should I make to the IP set-up?
TIA
-Robin.

I don''t know of you have some special, complicated setup (please describe, if so), but with a more or less "normal" dom0 I have not to make any changes after installing xen to get networking going. I had some machines with broken acpi tables where netowrking didn''t work fine, but then yopu have errors in dmesg output. Do you have any errors in xend log, syslog, dmesg?> After booting dom0 and starting xend, netstat gave > the usual output but I was unable to ping my router. Stopping iptables > had no effect. Looking again at the wiki article, I found a link to a > thread >(http://lists.xensource.com/archives/html/xen-devel/2005-01/msg00425.html)This is about xen 2.0.x and quite old, I wouldn''t bet anything that it is valid for any newer xen version. At least the bridge name is xenbr0 in xen 3 now. What version of xen are you using, which package, or from which source did you install, how does you config file look, do you see any error messages?

I let xend-config.sxp default, as it seemed to be what I wanted. -Robin. -- ---------------------------------------------------------------------- Robin Atwood.

I feel rather naked without the firewall, so I will have to look into that before going on. Meanwhile, every time I move the PS/2 mouse I get a million messages like: evbug.c: Event. Dev: isa0060/serio0/input0, Type: 4, Code: 4, Value: 28 Any idea what that''s about? Cheers... -Robin. -- ---------------------------------------------------------------------- Robin Atwood.

Or, unless you plan to debug some input hardware drivers, remove the evbug driver completely from your kernel. Or, maybe try adding a line "evbug" to /etc/hotplug/blacklist, to prevent automatic loading of that module. /Ernst _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

I found that "rc-update add xend boot" resulted in a painless boot. -Robin. -- ---------------------------------------------------------------------- Robin Atwood.
