Fixing a kernel panic error when installing Ubuntu 20.04 in VirtualBox

I was trying to create an Ubuntu 20.04 virtual machine using Oracle VirtualBox but I kept encountering this error with the message "...end kernel panic - not syncing: Attempted to kill the idle task!..." The screenshot below shows the error in VirtualBox.

Eventually, I found out the error was caused by inadequate alllocated CPU resources in VirtualBox. By default, the number of CPU allocated for the VM is 1, as shown in the screen shot below.

Simply increasing the number of CPU to at least 2 helped to solve the kernel panic error in this case.
