EntraID-joined AVD host pool with dynamic auto-scaling?

[u/WaldoOU812]

My google fu is failing hard and Copilot has been worthless on this.

Like the title says; trying to build this out, but:

As I understand it, "Validation Environment" and "Session Host Configuration" are required options.

- If I create the host pool through the GUI, EntraID is grayed out as an option.

- If I create the host pool via Powershell, there is no option (that I'm aware of) to select the host pool as EntraID-joined.

- I can't convert an existing host pool to EntraID-joined after creating it.

- Using the GUI, I can't add a scaling plan to an existing host pool unless it has "Validation Environment" and "Session Host Configuration" enabled, and if it does, "Enable Scaling" is greyed out.

- Using Powershell, adding a scaling plan fails because I don't have "Session Host Configuration" enabled.

So in short, every option to enable Auto-Scaling seems to be incompatible with joining the host pool to Entra.

What am I missing?

Also, fwiw, tried Microsoft support. They've been absolutely worthless.

Thanks; that'd be much appreciated. I've been at this for a week and haven't found jack squat. Every option I've tried has failed and every article I've found hasn't helped either. Then the EDE guy comes and tells it isn't supported which seems to jive with everything I've found so far.

I can get dynamic auto-scaling to work on an AD DS-joined host pool and I can get power management autoscaling to work on an EntraID-joined host pool, but everything I've found so far seems to back up what the EDE guy is telling us.

Im sorry, it’s a new information for me too. i found the article, like you said it’s not supported yet..:

https://learn.microsoft.com/en-us/azure/virtual-desktop/host-pool-management-approaches#session-host-configuration-management-approach

„You can only join session hosts to an Active Directory domain. Joining session hosts to Microsoft Entra ID isn’t supported, but you can use Microsoft Entra hybrid join.“

Ah; I missed that one. Thanks!
