Virtual Machine Agent Status is not Ready in WIndows VM
not able to log in to the Azure VM. The Serial Console and Run a Command are also not responding Please help to resolve this issue Backup is also not running. No Backup Available
Try this:
- Check Boot Diagnostics
- Go to the VM in the Azure Portal → Boot diagnostics
- If it's disabled, enable it to view screenshots and logs
- Look for signs of OS boot failure (e.g., stuck at login, blue screen)
- Verify VM Agent Health
- to see whether it may be missing, outdated, or corrupted
- Common causes: custom images, failed updates, or OS corruption
- Use Rescue VM Method
If you can't access the VM:
- Stop the VM
- Detach the OS disk
- Attach it to a healthy rescue VM as a data disk
- Use the rescue VM to:
- Check and fix corrupt system files (sfc /scannow)
- Reinstall or update the Azure VM Agent manually
- Remove problematic extensions
- Reattach and Start Original VM
- Detach the disk from the rescue VM
- Reattach it to the original VM as the OS disk
- Start the VM and check if the agent status improves
- Restore Backup or Redeploy
If recovery fails:
- Check if any snapshot or manual backup exists
- If not, consider redeploying the VM:
- Azure Portal → VM → Redeploy
- This moves the VM to a new host and can fix platform-level issues
- Prevent Future Issues
- Always use supported images with the Azure VM Agent pre-installed
- Keep the agent updated via Windows Update or manual install
- Monitor VM health via Azure Monitor and Security Center
