Windows Server instance VM created from Snapshot fails to Boot on GCE

[Hector Alexander Restrepo Jimenez]

I am trying to create a new VM instance on Google Compute Engine - GCE from a Snapshot which I created from Windows Server 2012 VM Instance couple of days ago . but I am never able to do RDP cause  may be Windows is not booting up properly. 

I get the Serial Port Output as following:

When i read the serial port 2 i get the following:

Computer is booting, SAC started and initialized. 
 
Use the "ch -?" command for information about using channels. 
Use the "?" command for general help. 
 
 
SAC> 
EVENT: The CMD command is now available. 
SAC> 
 


So, the firewall rule for tcp:3389 connection is allowed and i created other VM from snapshot successful. 

I followed the steps from stackoverflow forum but i still cannot access to this VM.

Any other suggestions to fix windows boot problems on GCE?

Your VM does appear to be starting up properly based on the fact that the GCE agent is looking for startup scripts and you can connect to the serial port.

This is more of an issue that requires troublehsooting, if you have any support packages, I strongly recommend opening a case with support. If you do not, this question is better suited for Stackoverflow.

The source VM instance of snapshot had a ip internal in windows. I reserved the ip internal from GCP console and i created a new VM instance from snapshot successfully.

As pwolXXXX@ mentioned, your Windows VM seems to have started correctly, so you should still be able to log in via serial console way. After which, I would check your OS configuration  as shown here.

If you spin up other Windows instances on the same network and you can RDP into them, then you can rule out a firewall issue at GCP level.
