Hi, Just want to add a few of my observations to what Tuna said.
a. I managed to have GRE isolation working with CloudStack 4.1.1 and a quick patch to bypass "enableXenserverNetwork" method. b. I tried GRE isolation with CloudStack 4.2.1 with the same quick patch for bypassing "enableXenserverNetwork". Once that method was bypassed, guest VMs came up, but the tunnel was not created. It seems to me that OvsElement methods (implement, prepare) are not invoked. Did something change in 4.2 to affect this ? I am setting "sdn.ovs.controller=true" in global settings and select GRE isolation method in the guest physical network.

Guys, Florin raised a problem in creating GRE tunnel with ACS 4.2 release and XenServer 6.2. I found the problem come from enableXenserverNetwork method. CloudStack made a tricky to create network when plugging a VIF to dom0 and then unplugging immediately. With XCP version I done in GSOC, I bypassed that step so that no problem. Didn't know why we need that tricky and how to solve it. I'm working on it. Any help or explaination?
