Virtual ethernet driver.

Virtual ethernet driver.

[Lukasz Grzelak]

Hello,

I trying to run XEN 2.0 (2.4.27, 2.4.28, 2.6.9) on gentoo 2004.3.

When i boot guest domain i get this:

anubis xen # xm create -f ttylinux -c

Using config file "ttylinux".

Perhaps start xend with 'xend trace_start' and then see if
xend.log can shed any light.

While the hang is going on, do you see the new vif if you do an
'ifconfig' in domain 0? Has it been added to the bridge?

Whatever the problem is, if you run Xend with tracing, the log files might 
reveal more information about where things went wrong.

Xend is intimately involved in setting up virtual devices, so it's quite 
possible we'd be able to figure out where /why it's hanging using the 
logs.

Cheers,
Mark

Have you used your own kernel config? You haven't disabled 
CONFIG_XEN_NETDEV_FRONTEND have you?

What happens if you use our binary install?

any hints? what's going wrong here? what's other than in older gentoo? 
it wasn't a problem like that to get xeno-unstable or 1.2 to work on 
older versions. devfs replaced with udev now.
