New VM MAC address restriction
-
Maybe this has been answered somewhere else and my quick search couldn't work out the keywords.
I'm looking to restrict (or at least set a default) for MAC address usage in XO/XCP-ng. In VMware, MAC addresses were limited to 00:50:56 (vCenter created) or 00:0c:29 (ESXi created) as a default. We currently use those first 6 octets to distinguish VMs from baremetal resources discovered on our network. I'm curious if there is a means of doing something like that as a default, in a template, etc. I understand individuals may be able to change it after the fact, but if I can set a standard for those first 6 inside XO/XCP-ng, it will make our VM create processes work better with our existing network discovery processes.

Hey
Thanks for your feedback, asking around

That's the part we need to change:
https://github.com/xapi-project/xen-api/blob/master/ocaml%2Fxapi%2Fxapi_vif_helpers.ml#L209But I think using the Xen OUI by default (
00:16:3e) could leak information on the hypervisor used
So we need to make it configurable. A XAPI issue will come next week and we'll see how to work with it -
Pinging @BenjiReis as a reminder so we can discuss this somewhere next week

@olivierlambert Did anything ever come of this?
-
It's doable but it's not yet on top priority list to our work on getting 8.3 released. But IIRC it's in our backlog, right @BenjiReis ?
-
It's in the backlog indeed but I don't know when the ETA to start this.
I guess an issue in the xen-api repo would be a good first step to see what the XAPI team think of the feature.
