NAME

       kvm-ok  -  determine  if this system is capable of running hardware accelerated KVM virtual machines (ie,
       possesses Virtualization Technology)

DESCRIPTION

       kvm-ok is a program that will determine if the locate system can host hardware  accelerated  KVM  virtual
       machines.

       The  program  will  first  determine  if /proc/cpuinfo contains the flags indicating that the CPU has the
       Virtualization Technology (VT) capability.

       Next, it will check if the /dev/kvm device exists.

       If running as root, it will check your CPU's MSRs to see if VT is disabled in the BIOS.

       In some failure cases, kvm-ok provides hints on how you might go about enabling KVM on a system where  it
       is arbitrarily disabled.

       If KVM can be used, this script will exit 0, otherwise it will exit non-zero.

SEE ALSO

       kvm(1), dmesg(1)

FILES

       /proc/cpuinfo, /dev/kvm

BUGS

       The  disabled-by-bios  check currently scans dmesg(1) for a message displayed by the kernel.  This is not
       ideal, in that a long-running system will eventually roll the dmesg logs.  The kernel should  expose  the
       disabled-by-bios flag in /proc/cpuinfo.
