Sangfor SCP Restore Failed with Sangfor Trial License

Discovered Version：v9.0.0

Question

On a Sangfor SCP (Hyper-Converged Infrastructure) Trial edition environment, virtual machine restore tasks initiated via Vinchin fail with the error: 

[ERROR:46#Task failed]: execute task error, 
vm_manage_server [4059244:4059252] [ERROR:46#Task failed]: execute task error, task_id: cd393a8d-42db-11f1-b6ed-fefcfe56757c, err_msg: This Hyper-Converged Infrastructure is Trial edition. 
The maximum CPU cores per virtual machine is 4. Please contact a technical support representative to upgrade license. 

Answer

Issue Description

Sangfor SCP Trial edition license restriction: maximum CPU cores per virtual machine is 4. When Vinchin restores a VM, it preserves the original VM's CPU configuration (6 cores in this case), which exceeds the Trial license limit and causes the restore to fail.

Resolution

Option 1: Adjust Restored VM CPU Configuration (Verified ✅)

• Method A: Reduce CPU sockets (e.g., sockets=6 → sockets=4)
• Method B: Reduce CPU cores per socket while keeping total ≤ 4
• Principle: cores × sockets ≤ 4

Option 2: Upgrade SCP License (Recommended for Production)

Contact Sangfor technical support to upgrade to a production license, removing the CPU core limit:
