NAME
       kvm-ok - determine if this system is capable of running hardware accel‐
       erated 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) capabil‐
       ity.

       Next, it will scan your dmesg(1) log to see if your kernel has detected
       that VT is disabled in the BIOS.

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

       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  dis‐
       played by the kernel.  This is not ideal, in that a long-running system
       will eventually roll the dmesg logs.  The kernel should expose the dis‐
       abled-by-bios flag in /proc/cpuinfo.
