<br></blockquote><div> </div></div>Hi Jim,<br><br></div><div class="gmail_extra">You could create another VM to check if there is connectivity between them.<br>Then use tcpdump on the host bridge and on your nic while you ping, check if you see the packets and their correct tag.<br></div><div class="gmail_extra">I would also check if you have by mistake a duplicate mac address for the VM (your will need to check your switch for that).<br></div><div class="gmail_extra"></div><div class="gmail_extra"><br></div><div class="gmail_extra">How did you configured the switch this nic is connected to?<br><br></div><div class="gmail_extra">You could also share your current setup config for us to see: (from host and VM)<br></div><div class="gmail_extra">- ip addr<br></div><div class="gmail_extra">- ip route<br></div><div class="gmail_extra">- brctl show (only for host)<br></div><div class="gmail_extra"><br></div><div class="gmail_extra">Thanks,<br></div><div class="gmail_extra">Edy.<br><br></div></div>
