Re: [Xen-devel] After switching from "xm" to "xl" toolstack, can't get Guest networking to work.

[erin.balid@xxxxxxxxxxxx]

Hi All.

I wanted to do an apples-to-apples comparison of "xm" and "xl".

Using a config file VIF of

        vif=['mac=00:16:3E:12:34:01,bridge=br0']

If I turn on  xend and start the Guest with 'xm create', networking at
the Guest is OK.
If I turn off xend and start the Guest with 'xl create', networking at
the Guest fails, I think because the Guest's VIF doesn't get assigned to
the Host bridge.
