Hi, I've pushed the early stage code for private vlan support to the repo.
The FS is at: https://cwiki.apache.org/confluence/display/CLOUDSTACK/PVLAN+for+isolation+within+a+VLAN The effort are on simulation PVLAN(isolated secondary vlan) using openflow on OVS. But I have to admit it's really less than ideal, especially the "vm in the dhcp host" script. Ideally, when we want to setup pvlan, we need just tell that enable it for a VM or enable it for DHCP server. But after spending all the effort try to find a way on ovs(supported openflow 1.0), I realize we need higher version of openflow support, which I explained in FS. Currently we need to also tell VM on the same host with DHCP server, apart from other VMs, and programming different rules. It's unusual for CloudStack, and result in some hack code as well. The current code can start/stop VM and DHCP server, but haven't got migration work done. If you're interesting, please take a look at the branch. --Sheng
