Hello,
Whene I choice the VM sku "Standard_E16ds_v4", it's impossible to install Hyper-V role on nesteed VM.
“Please ensure nested virtualization is enabled in order to successfully install Hyper-V on azshcinode0X.azshci.local.”

But nesteed features are enabled on the VM:

With the sku "Standard_E16s_v4" I don't have issue.
Thanks
