   kvm is not a BIOS issue.  It is the Linux Kernel Virtual Machine, a   
   hypervisor built into the kernel itself (or as a loadable module), but   
   it requires a userspace component - a modified version of Qemu, although   
   it can now also use unmodified Qemu.   
      
   In esssence, kvm allows Linux to behave as a hypervisor, and thus to   
   virtualize and to schedule virtual machines directly.  You do however   
   still need Qemu because kvm does not provide any emulation.
