<div dir="ltr"><div>I think trunk mode is the way to go. If you use multiple vlans, it's the only way to go.<br><br>Trunk mode changes the switch port from an access port, which allows a single device to be connected, to a trunk, which will allow multiple devices to be connected on the same port. Because you have multiple guests running in KVM, the switch sees the bridge port on the KVM host as another switch, causing the port to be shut down by spanning tree.<br><br></div>Brian<br></div><div class="gmail_extra"><br><div class="gmail_quote">On Fri, May 15, 2015 at 12:45 PM, Chuck Payne <span dir="ltr"><<a href="mailto:terrorpup@gmail.com" target="_blank">terrorpup@gmail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr">Brain thank, I was thinking it might be trunk.
