Run 64bit Guest on 32bit Host Virtualbox

Virtualbox is really cool software for virtualization and it is free. Latest version of virtualbox support running 64bit guest, even on 32bit host. See this checklist:
  1. Make sure your processor support VT-x (or AMD-v) and 64bit
  2. Enable in BIOS: Virtual Machine Technology
  3. set option in guest: PAE, IOAPIC, ACPI to enabled
  4. And most important thing: set OSType to Ubuntu_64 or Windows_64 (note the _64)
  5. Install your guest OS (i prefer using headless and rdp)
