asked on DL160 Gen9 doesn't appear to support SLAT
Hi,
I bought an HP server (830582-425) a few months ago and I would like to run Microsoft VDI on it.
I ran the coreinfo.exe command on the server and these are the results (attached)

It seems the server does not support EPT which is needed for SLAT.
I found an article which says some HP servers incorrectly state they don't support SLAT

The BIOS settings are all correct but the coreinfo.exe command returns the same results.

The snip indicates Intel's name for SLAT is there: EPT

Hi, thank you for responding. You're both almost right. The server spec does say it supports SLAT/EPT and the EPT is listed in the snip but Coreinfo.exe -v has a - instead of a *. The - indicates the the feature is missing but * should indicate the feature is installed. I suspect there is something I need to do to enable it but the virtualization BIOS settings are all enabled.

Hi, I have been running Hyper-V and VM's fine but I want to use Remote Desktop Virtual Desktop Infrastructure. It does not work without SLAT/EPT

VDI uses Hyper-V. If there are VMs up and running then VDI will work as that's all VDI is: A pool of Remote Desktop Session Hosts or Windows Desktop OS VMs.

Thanks Gents!
Patrick, I have already seen the link you are referring to and that's what brought me here. coreinfo.exe is hiding the EPT/SLAT feature from the OS. I have tried the fix suggested. Checking the BIOS etc. All virtualization settings are correct. I was wondering if I might be missing something else?

Did you try to install the RDS installation? If Yes, were you presented an error?
No more question from poster
According to Intel it does support EPT.
