ESXi hyperthreading

I enabled hyperthreading on UCS and the ESXi 6.0, but it’s still showing “inactive” on the ESXi.  Anyone have seen this before ? attachment included

Power off your ESXi host and then power it back on.

As daphnissov says, reboot the ESXi host.

I found my self that sometimes when enabling HT it doesn't show as "enabled" until you reboot the host.

Also you can check the status via esxcli on the host, as maybe the vSphere Web client it doesn't show it properly:

esxcli hardware cpu global get

will do and get back to you with the results. I hope it's that easy 🙂 .

Thanks for the quick response.

To clarify:  You will likely need to perform a power cycle on this host and not just a warm reboot.
