Hello,
Did You specify also the given IP 172.31.53.254 in your DomU? If the
DomU is not accessible from Dom0, I suppose it is also in the opposite way -
Dom0 is not accessible from Dom0? Are there also any error messages in the
Dom0 log files or any other error messages in DomU?
With best regards
Archie

Subject: Re: [Xen-users] Network routing setup problem; domU won't start
Getting back to my "xm create" network failure:
I think I figured out at least part of what was going wrong. I
needed to add a "netdev=" parameter in my "vif-script" line. Once
I did this, the domU came up OK.
However, I've still got a problem. The new domU does not seem to
be accessible via the net -- not even from the dom0.
Here's what I have so far. (I moved the "ifconfig" settings for
dom0's dummy interface to my internal bridge out of my custom
network script and into /etc/network/interfaces.)
I notice, BTW, that none of the vif#.#'s in my dom0 have been
assigned the IP address of my domU. I thought that was supposed
to happen; or am I misunderstanding how the networking works?
