VirtualBox 6 Virtual Machine with more than 1 core and kernel 4* freezes
When I try to set a VM with more than 1 core CPU, the guest system freezes quickly.
I opened a thread on the VirtualBox forum and they said that is a Linux problem (WBox forum moderator told me that this is an Ubuntu bug).
I had tried the KVM option (as suggested in the answer below) and other settings... AMD-VT, PAE, Nested pages, etc, but nothing makes the VM stable. The error I get most frequently is a loop that prints in TTY1
CPU #03 stuck for 23 sec
As I said in the WB forum a VM with 6 CPUs is still running very fast with the old 3.13.0-164-lowlatency kernel, but I can't use that because it's no longer supported.
What could be the problem, and how can I fix it?

Try explicitly setting paravirtualization (in settings/system/acceleration) to KVM or Hyper-V, rather than legacy.
