Description<\/h1>\n

When you update your ESXi host you can see on ESXi’s summary tab this warning.
\n\"\"<\/a>
\nI decided to use PowerCLI to solve this issue. Please, for more information or verify compatibility CPU follow this link (https:\/\/kb.vmware.com\/s\/article\/55806<\/a>).\u00a0You can follow this link (https:\/\/kb.vmware.com\/s\/article\/55636<\/a>) as well.<\/p>\n

Script<\/h1>\n

FYI, you can add an array for option “Name” on Get-VMHost.<\/p>\n

$esxcli = Get-EsxCli -VMHost (Get-VMHost -Name MyESXiHost) -V2\r\n$SettingsKernelSet = $esxcli.system.settings.kernel.set.CreateArgs()\r\n$SettingsKernelSet.setting = \"hyperthreadingMitigation\"\r\n$SettingsKernelSet.value = \"TRUE\"\r\n$esxcli.system.settings.kernel.set.Invoke($SettingsKernelSet)<\/pre>\n
Verify if new value is applied.<\/p>\n
$esxcli = Get-EsxCli -VMHost (Get-VMHost -Name MyESXiHost) -V2\r\n$esxcli.system.settings.kernel.list.Invoke(@{option = \"hyperthreadingMitigation\"})\r\n<\/pre>\n
You have to reboot the ESXi host for the configuration change to go into effect.<\/p>\n
Have Fun !!<\/p>\n","protected":false},"excerpt":{"rendered":"
