Yes, I too faced this error! I was using Seed Ubuntu Machines 12.04 and 16.04. My both machines showed this error. I got it resolved by following steps:

  1. Change the processor count to 2(if 1).
  2. Enable I/O APIC in motherboard settings.

Note: If invalid settings shown below, check and resolve accordingly.

Hope it helps.

Maybe try to Check if there is any warnings on the vmbox setting, for me i had the same problem but i changed the display settings to the recommended one VMSVGA and changed the number of processors to two so try the first one

  1. also make sure you have Virtualization Technology enabled it maybe a cause for the problem
  2. change display settings to VMSVGA if did not work
  3. change number of processors to two
