kvm-ok

Langue: en

Section: 1 (Commandes utilisateur)

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 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 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.

Le Desdicygne

Moi, veuf, inconsolé, ténébreux aujourd'hui
Sans ma tour abolie, prince d'Aquitaine ivre,
Je pleure l'astre mort au luth taché de givre.
Mélancolie, soleil noir, mon bonheur a fui !

Dans la nuit du tombeau, par toi l'espoir a lui :
Rends-moi mer d'Italie, Pausilippe, et délivre
mon coeur si désolé, par la fleur qui fait vivre :
Que le pampre et la rose égayent mon ennui !

Lusignan ou Biron, Phébus à l'agonie,
Amour, baiser royal qu'un front rougi ne nie,
En ta grotte, sirène, à rêver tu me pris.

Deux fois sur l'Achéron la victoire on m'assigne,
Où la lyre d'Orphée module sans mépris
Soupirs de sainte, ou cris de fée, ou chant du Cygne.

Gérane de Nervarmé
