Reason:

Check whether the VM meets the condition: (number of network cards × number of cores) ≤ memory. If (number of network cards × number of cores) exceeds the memory capacity, the VM may get stuck on a black screen.

Example: Suppose a virtual machine is configured with 4 network cards and 8 cores, while its memory is only 24 GB. Here, the calculation result of (4 × 8) is 32, which is greater than the memory value of 24. In this case, the virtual machine is likely to encounter a black screen freeze.

Solution:

Delete the unnecessary extra network cards of the VM or increase the memory of the VM.
