.virtualbox Error

Big Sur설치후 아래와 같은 에러가 발생…

virtualbox Error

Kernel driver not installed (rc=-1908)

Make sure the kernel module has been loaded successfully.

where: suplibOsInit what: 3 VERR_VM_DRIVER_NOT_INSTALLED (-1908) – The support driver is not installed. On linux, open returned ENOENT.

The virtual machine ‘win10’ has terminated unexpectedly during startup with exit code 1 (0x1).

Result Code:	NS_ERROR_FAILURE (0x80004005)
Component:	MachineWrap

solution

reinstall virtualbox & allow Security

에러발생시, vritualbox를 재설치하면, 보안 설정에 아래와 같이 oracle을 열어줄 건가 묻는 부분이 30분간 활성화 되어 있는데, Allow를 눌러 주면 해결됨
