I am using below script to get service information from the windows guest os using invoke-vmscript but for few vms the credentials which i provided in the script are not valid so for those vms i am not getting any error output or vmname with blank result in output $report.
So is it possible to write the error output while using wait-task because when I look at the powershell console the wait-task is displaying the error 'Failed to authenticate with the guest operating system using the supplied credentials' but in the $task.Result.ScriptOutput is not showing up the authentication failed error and even $task.Result.VM.Name is not showing up the vm name.
I am ok for few vms if authentication failed or any other error but expecting to write that error in $report for those vmnames.
$script = @'
$output=Get-Service |select Name
$output.Name -join ','
'@
$tasks = @()
foreach($singlevm in Get-VM test01,test02,test03,test04,test05,test06,test07){
$sInvoke = @{
VM = $singlevm.Name
GuestUser = 'administrator'
GuestPassword = 'password'
ScriptText = $script
ScriptType = 'Powershell'
ErrorAction = 'Stop'
}
$tasks+=Invoke-VMScript @sInvoke -RunAsync -Confirm:$false
}
Wait-Task -Task $tasks -Verbose
$report=foreach ($task in $tasks) {
'' | Select-Object @{N='VM';E={$task.Result.VM.Name}},
@{N ='Result'; E={$task.Result.ScriptOutput.Split("`n") |Where-Object { $_ -ne '' } | %{$_.Trim("`r`n")}}}
}

If I run like this nothing is captured in $tasks
$script = @'
$output=Get-Service |select Name
$output.Name -join ','
'@
$tasks = @()
foreach($singlevm in Get-VM 'Win2k16_Std_64bit-testClone'){
$sInvoke = @{
VM = $singlevm.Name
GuestUser = 'administrator'
GuestPassword = 'password'
ScriptText = $script
ScriptType = 'Powershell'
ErrorAction = 'Stop'
}
$tasks+=Invoke-VMScript @sInvoke
#-RunAsync -Confirm:$false
}
Yes LucD by using your last script I used try catch method now but its not giving any results. How to use with -RunAsync switch and Wait-Task -Task $tasks because I need to run on large set of vms and with -RunAsync will give results more quicker.
$script = @'
$output=Get-Service |select Name
$output.Name -join ','
'@
$tasks = @()
foreach($singlevm in Get-VM 'Win2k16_Std_64bit-testClone'){
try {
$sInvoke = @{
VM = $singlevm.Name
GuestUser = 'administrator'
GuestPassword = 'password'
ScriptText = $script
ScriptType = 'Powershell'
ErrorAction = 'Stop'
}
$tasks+=Invoke-VMScript @sInvoke -RunAsync -Confirm:$false
break
}
catch {
}
}
Wait-Task -Task $tasks -Verbose
$report=foreach ($task in $tasks) {
'' | Select-Object @{N='VM';E={$task.Result.VM.Name}},
@{N ='Result'; E={$task.Result.ScriptOutput.Split("`n") |Where-Object { $_ -ne '' } | %{$_.Trim("`r`n")}}}
}

Its not displaying any output for vms when authentication is success.
When authentication fails its writing the output.
I am also thinking instead of Write-Output can we keep it in one variable for both failure and success machines so that I can export to csv.
Some issue. I am not getting the output. Below is the output.
For the same VM if I execute as below I can see the output.
Looks like the copy/paste had an error.
The Invoke-VMScript was called twice. I corrected that
I just did some more testing with 2 targets, one with a correct password and one with an incorrect password.
And the result is what I expected.
