GitHub user cisco-abrandel added a comment to the discussion: Cloudstack creates VLAN sub-interface on wrong interface on KVM
I was seeing what I *thought* were issues related to this, but it turns out the issues were elsewhere. For full disclosure, we're running some small KVM test hosts on VMware, and has promiscuous enabled for the port group. This caused some minor looping of packets, one side effect of which was the linux bridge learned the KVM guests MAC on the wrong port occasionally, causing traffic blackholing. The solution for our specific topology was to disable promiscuous on the VMware port group the KVM host are in, and instead use MAC learning on the DVS.
