I've seen a poor choice made for a disconnected nic as the primary interface and it still worked because it got bridged to the actually connected nic.<div><br></div><div>-Tom</div><div><br></div><div><br><div><div>On Jul 26, 2010, at 5:23 PM, Matthew Nuzum wrote:</div><br class="Apple-interchange-newline"><blockquote type="cite"><div class="gmail_quote">On Mon, Jul 26, 2010 at 4:55 PM, Tom Pohl <span dir="ltr"><<a href="mailto:tom@tcpconsulting.com">tom@tcpconsulting.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;">

</div><div>Yes, it is virtualized. It's a xen dom0 with three domu's running. Total server ram is 2G and each guest is using 512MB. Practically no swap is being used in any except the guest that actually has something active but the swap appears to be mostly just idle stuff. There's a significant amount of free RAM available. Load average is low on all.</div>
<div><br></div><div>I can duplicate the slow http access to content in both VMs that I tested on (the one that is active and one that is newly created and idle) which leads me to believe it's something either related to the entire server or the network that the server is on.</div>
