If you wish to install GUI tool run command: $ sudo apt-get install qemu-kvm libvirt-bin bridge- utils Install KVM and necessary user-space tools with apt-get command: If 1 or more it does - but you still need to make sure that virtualization is enabled in the BIOS. I f 0 it means that your CPU doesn't support hardware virtualization. To see if your processor supports one of these, ecxecute: Intel and AMD both have developed extensions for their processors, deemed respectively Intel VT-x and AMD-V. If hardware virtuaslisation is not supported, you can still run virtual machines, but it will be much slower without the KVM extension. To run KVM, you need a processor that supports hardware virtualization. If 0 is printed, it means that your CPU is not 64-bit.Ĭheck that your CPU supports hardware virtualization To check if your processor supports 64-bit instructions execute: If you have i386, i486, i586 or i686 in output, then you are running a 32-bit kernel. X86_64 tells you are runnig 64-bit kernel. Also a 32-bit system limits maximum amount of RAM you assing to a guest OS to 2GB. It is recomended that you use a 64-bit system for your host OS because a 64-bit system can host both 32-bit and 64-bit guests, and 32-bit system can only host 32-bit guests. Each virtual machine has private virtualized hardware: a network card, disk, graphics adapter, etc. Using KVM, one can run multiple virtual machines running unmodified Linux or Windows images. KVM also requires a modified QEMU although work is underway to get the required changes upstream. It consists of a loadable kernel module, kvm.ko, that provides the core virtualization infrastructure and a processor specific module, kvm-intel.ko or kvm-amd.ko. KVM (for Kernel-based Virtual Machine) is a full virtualization solution for Linux on x86 hardware containing virtualization extensions (Intel VT or AMD-V).
