Guys,
We are currently upgrading out network gear, which is a mix Cisco Small
Business and Netgear Smart switches. We don't have any vlans. Our KVM
servers are working with them with no issues.
We purchased a couple of Cisco 2960-x switches. We were trying to move a
couple of our Red Hat KVM servers to it, but we are having issues getting
the bridge device to work the same way.
The first thing we noticed is that the switch turn off the port when w
e hooked up the bridge port to the switch. We found out that it was cause
by bpdugard. We disable able and the bridge was able to connect aand we
could connect to the bridge of the server from other boxes, but we could
not connect to any of the guest on the that bridge.
Now, when I am KVM host, I can ping the guest. When I am the guess I can
ping the host bridge ip. But from other boxes I can't ping the guest, and
from the guest I can't ping the other boxes.
Example
Host Br3 10.0.0.10 < - - - - - - > 10.0.0.12 Guest eth0
External Box 10.0.0.5 ---> 10.0.0.10 Host xxxxxx 10.0.0.12 Guest
Guest 10.0.0.12 --> 10.0.0.10 Host xxxx 10.0.0.5 External Box
Here what bridge control show
bridge name bridge id STP enabled interfaces
br3 8000.d4ae52a5feb2 yes em2
vnet19
On the switch I have turn on spanning tree hoping that would help.
Is there something I need to do on the KVM side? Do have to set the
port maybe as trunk? I am total lost, sorry I am not Cisco Guru. I
know someone has ran into this.
