netconsole doesn't work under xen kernel

When you try to start netconsole under a xen kernel, you get:
netconsole: local port 6665
netconsole: local IP 172.16.59.133
netconsole: interface eth0
netconsole: remote port 6666
netconsole: remote IP 172.16.57.196
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?
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...
