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


       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.


       kvm(1), dmesg(1)


       /proc/cpuinfo, /dev/kvm


       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.
