How to migrate export to virtual box if ec2's os is linux?

I am migrating an aws ec2 instance to virtualbox which is on premise.

I did it by referring to the following document: https://docs.aws.amazon.com/vm-import/latest/userguide/vmexport.html

If the os is ubuntu, it went well, but in the case of amazon linux 2, the system log appeared and did not go beyond the black screen.

So I checked the logs and got the following error:

00:00:16.963092 GIM: KVM: VCPU 1: Enabled system-time struct. at 0x000000011ff5a040 - u32TscScale=0xc587c2ef i8TscShift=-1 uVersion=2 fFlags=0x1 uTsc=0x53fcdb5f1 uVirtNanoTS=0x20670f8e0 TscKHz=2592006

00:00:22.241561 PIIX3 ATA: Ctl#1: finished processing RESET

(It ran normally in VMWARE.)

If the instance of ec2 uses amazon linux2, is there anything else I need to do other than what is in the document when exporting the image and importing it to virtual box?
