I have the same question. Maybe you need to update to the latest version if one is available?
Managed disks aren't support right now as far as I know. Asking about future version of the plug-in and features would be better asked in the vRO forums since the devs responsible often lurk there.
Moved into vRO forum as requested.
Do any of the vRO Devs have insight on this issue? Thanks.
*Bump*
This is becoming a more important issue for our business. Does anyone know if managed disks will be supported in the near future?
I have the same question.
How can I use vRA to build Azure machines with managed disks
