This blog post is not about the L1 Terminal Fault (L1TF -> VMware KB56931) but about the HTAware Mitigation tool version 18.104.22.168 (HTAwareMitigation-22.214.171.124.zip) that seems to have issues when used on single hosts (instead of clusters) – here is the problem that I have observed.
You run the command:
Set-HTAwareMitigationConfig -VMhostName <hostname> -Enable
Get-HTAwareMitigationConfig -VMhostName <hostname>
As you might see the “Set-HTAwareMitigationConfig -VMhostname <hostname>” command doesn’t seem to do anything!
