With MAAS, I find the power operations via IPMITOOL to be quite useful when managing servers, but I keep getting requests from users for access to the IPMI console - in this case Dell iDRAC 8/9 HTML5 consoles.
Would it ever be possible to have console access to the DRAC/ILO/IPMI to see and interact with the server from MAAS? Since the system is already filling in the information and creating the appropriate user anyway. I know there have been issues in the past with proxying IPMI consoles on other platforms (usually gotten around by using a 1:1 NAT or similar) when dealing with web applications.
Ideally you would want MAAS to act as a front-end that proxies back to the IPMI address and pulls up the console, and in the case of DRAC they have a fully operational REDFISH API that can even be used.
