Service Template: Automatic Machine Rebooting and Script Restarting via Exit Code in Script Application

Question

Hello,
My question is on Script Applications in
Service Templates:
In VM Templates, in the Application Configuration tab, one can add a Script Application. This can be a PowerShell script, a batch script, etc.
For each Script Application, it is possible (via the Advanced options) to make the
machine reboot when the script exits with one of three
exit codes: 1641, 3010 and 3011.
Problem:
For PowerShell or PS scripts, if I use ‘exit 3010’, the machine should reboot but it doesn’t…
Bad workaround:
Use a batch script which calls the PS script. Then, exit out of the batch script using ‘exit $LASTEXITCODE’. This works. The machine reboots.
I can’t use the workaround. Is there a way to do this using just the PS script?

In fact yes.
You actually want SCVMM to orchestrate the reboot by sending the proper exit code.  Otherwise SCVMM gets all weird about things.
It is in the advanced settings for the script and / or command.
You need to make sure that your script tosses the 3011 or 3010 on exit.
I do it with the 3011:
# Exit 3011
[Environment]::Exit(“3011”)
In the XML you will find this:
<vmmst:RebootExitCodeRegex>{1641}|{3010}|{3011}</vmmst:RebootExitCodeRegex>
But you do not want to enable restarting the script on each reboot or you will find yourself in a loop.
