<p class="MsoNormal">I don't understand the <network> part here. It doesn't seem to be documented. I inherited these pieces<o:p></o:p></p>

<p class="MsoNormal">If, instead, I have the following, the guest comes up with no network interface at all<o:p></o:p></p>

<p class="MsoNormal">makes it start with "eth0", but no address has been assigned. I can manually do that and then<o:p></o:p></p>
<p class="MsoNormal">I can communicate with the host but it's kind of a pain to add the address and routing manually.<o:p></o:p></p>
<p class="MsoNormal">Oddly enough, though, ping from host to guest works normally, but ping guest to host seems to succeed once<o:p></o:p></p>

<p class="MsoNormal">Am I doing something wrong, here? And, if anyone could advise how to use openvswitch<o:p></o:p></p>
