<div dir="ltr"><div class="gmail_quote"><div dir="ltr">Hi,<br><br>I was playing with OpenStack Neutron with OVS plugin. When I launch VMs, I noticed that there is a Linux bridge (qbrxxx) created for each VM, which is then connected to the OVS bridge (ovs-int). See the following.<br>
<br> VM0 VM2<br> | |<br> qbrXXX qbrYYY (per-VM linux bridges)<br> | |<br> | | <br> br-int (OVS bridge)<br>
|<br> br-eth<br><br>My question is, why couldn't VMs be directly connected to br-int (without qbr Linux bridges)? Why do we create additional Linux bridges between OVS bridge and VMs? What is the role of Linux bridges here?<br>
<br>Thanks!<span class="HOEnZb"><font color="#888888"><br>-Dan</font></span></div>
