Description Jeff Layton 2007-01-23 13:16:20 EST
+++ This bug was initially created as a clone of Bug #224023 +++

When you try to start netconsole under a xen kernel, you get:

netconsole: local port 6665
netconsole: local IP
netconsole: interface eth0
netconsole: remote port 6666
netconsole: remote IP
netconsole: remote ethernet address 00:16:35:36:af:1e
netconsole: eth0 doesn't support polling, aborting.

The same operation works fine on the same hardware with a non xen kernel.

Ethernet interface is:

06:06.0 Ethernet controller: Realtek Semiconductor Co., Ltd.
RTL-8139/8139C/8139C+ (rev 10)

It should work fine if you start it before xend, or if you use peth0 instead of
eth0 after xend is running.  Does that help?
Comment 2 Jeff Layton 2007-02-16 12:50:07 EST
We don't ship startup scripts for netconsole alone, but we do ship one for
netdump and you can set it up to just start netconsole by just setting
$NETLOGADDR and not $NETDUMPADDR. When I configured this and chkconfig'ed it on
at boot time, it started it before xend and did work as expected.

I think we can probably close this as NOTABUG. I'll go ahead and do that...
