Debug Output/Panic Output
Full debug output not needed. But this is the error message:
There appears to be no way to add the ultra SSD capability to the dedicated host group in terraform at this time.
Expected Behaviour
I should be able to add a block to the dedicated host group, like
Actual Behaviour
I'm not allowed to add the capability to the host group.
Steps to Reproduce
