Citrix Hypervisor 8.1 released

@GHW @olivierlambert The Access Control lists in the DVSC instance was easily one of its most powerful and useful features. It essentially turned the DVS into an actual port-level security capable virtual switch. If it had full-featured routing, it would have been a very nifty solution to layer 3 in the virtual network space without having to run an entirely different appliance to achieve that capability. Perhaps that is something that the SDN could do at some point? (become a layer 3 capable switch with security access control)

Sadly I have no DVSC knowledge myself, so it would be great if you are able to explain in a kind of simple "high level specification" (eh "doing this in the UI with a screenshot, it does that") in a Github issue for SDN plugin, we might implement it on our side

So does the removal of the DMC mean that we wont be able to over-commit memory anymore?

A bit of good news is that the DVSC works out of the box with XCP-ng 8.0. Though I have not tested it in conjunction with the SDN plug-in.
After importing the DVSC and adding it to the resource pool:
.1) Select the VM you want to apply security ACLs to
.2) Select "Access Control" and here you can create a network ACL policy to control traffic to and from the VM (by default there are no restrictions)
.3) Apply your desired network security policy to the VM
Results
Allows ping to 8.8.8.8 but blocks ping to 8.8.4.4 since it is not allowed in ACL policy
Allows access to HTTP web server as defined in the the VM network ACL policy and blocks access to the other
Restricts SSH access to trusted hosts

Thanks I'm pinging @BenjiReis who built the SDN plugin

@olivierlambert thanks

@GHW this is in our internal roadmap. So before doing any promises, we'll see first if we can do a working PoC. Depending on priorities, we could target a firm answer (will it be released one day) in Q1, and if yes to the previous question, might be Q2.

@olivierlambert Awesome and thank you for the follow-up.
