Check your particular virtual machine settings in VirtualBox's VM
Manager -- System -> Acceleration -- that both hardware accelerations
options, VT-x/AMD-V and Nested Paging, are enabled. If they are
already enabled, check your motherboard BIOS' CPU settings for
similar options.
Now download and read/study VirtualBox's VERY complete user manual.
Yes! I really do mean read the entire fucking manual, cover to cover.
It's the only reference I've ever needed in the dozen or so years I've
been using VirtualBox. It's Troubleshooting Section is particularly
useful.
