I think Chip's reply might be a bit harsh :smileygrin:
There is indeed quite some information available on how to suppress the message, but the KB only mentions a manual method (shame on you KB :smileygrin:).
And since this is a community around 'automation', and since changing it in an automated way is not so straight-forward (at least it wasn't to me), attached a script I use.
$arg = @{ option = '/UserVars/SuppressHyperthreadWarning'
intvalue = 1
}
Get-VMHost | ForEach-Object -Process {
$esxcli = Get-EsxCli -VMHost $_ -v2
$opt = $esxcli.system.settings.advanced.list.Invoke() | where {$_.Path -eq '/UserVars/SuppressHyperthreadWarning'}
if ($opt) {
if ($opt.intvalue -ne 1) {
$esxcli.system.settings.advanced.set.Invoke($arg)
}
else {
Write-Output "Setting already correct on $($esxcli.VMHost.Name)"
}
}
else {
Write-Output "Setting not present on $($esxcli.VMHost.Name)"
}
}
