Re: [Xen-users] No dom0/domU ping "out of the box"

["Colin Brown" <brownc@xxxxxxxxxxxx>]

Patrick,

Thanks for responding.

Just double-checked: I am using (network-script 'network-bridge')

Oops, I reported only the up interfaces (ifconfig without -a).  With
ifconfig -a, I do see the 8 vif0.? and 8 veth? interfaces -- all are
down.  But no sign of peth0, the new name for the physical interface.

Since my original post, I discovered in the xend-debug.log a message at
the top:
  ifdown: interface eth0 not configured
  SIOCSIFNAME: Device or resource busy
But it appears in the script that failure of ifdown is expected since
there is an alternative path when that occurs.

You SHOULD see eight vif0.# interfaces and eight veth# interfaces when
you run "ifconfig -a".  If you're not seeing them, then I'm betting you
configured /boot/grub/menu.lst to pass "loopback.nloopbacks=0" to the
dom0 kernel?  Don't do that.  You need at least 1 loopback in dom0 for
the network-bridge script to do it's magic.

The other possibility is that you didn't configure xend-config.sxp with:

        (network-script 'network-bridge')

You'll need that if you want your system to look like the wiki docs.
