Troubleshooting cloning issues

This topic provides troubleshooting guidelines when FortiSandbox fails to finish cloning a custom image.

To troubleshoot this issue:

1. Log in as and Admin user.
2. Go to Scan Policy and Object > VM Settings and change all other VM types' clone # to 0, and the failed one (customized image) to 1.
3. Click Apply to trigger the cloning.
4. Click the View Running VMs button on this page. In the dialog box, keep clicking the Screenshot button of the failed VM.
5. Click the PNG Link image icon to show the screen shot. The image might provide the reason for the failure.

Common reasons for failure:

Reason	Solution
The custom image is too large for amount the of system memory	Reduce the size of the custom image with Windows Disk Defragmentation tool, or Reduce the clone number
The customized image license is deactivated	Activate the customized image license.
The system is not configured properly	See the FortiSandbox Administration Guide in the Fortinet Document Library.
The newer CPU is not compatible with the Hypervisor of the FortiSandbox causing the VM to load slow, show black screen or unable to start.	Contact the Support team to provide a potential hot-fix.
