  12 What distribution is {pve} based on?::
  13
  14 {pve} is based on http://www.debian.org[Debian GNU/Linux]
  15
  16 What license does the {pve} project use?::
  17
  18 {pve} code is licensed under the GNU Affero General Public License,
  19 version 3.
  20
  21 Will {pve} run on a 32bit processor?::
  22
  23 {pve} works only on 64-bit CPU´s (AMD or Intel). There is no plan
  24 for 32-bit for the platform.
  25 +
  26 NOTE: VMs and Containers can be both 32-bit and/or 64-bit.
  27
  28 Does my CPU support virtualization?::
  29
  30 To check if your CPU is virtualization compatible, check for the "vmx"
  31 or "svm" tag in this command output:
  32 +
  33 ----
  34 egrep '(vmx|svm)' /proc/cpuinfo
  35 ----
  36
  37 Supported Intel CPUs::
  38
  39 64-bit processors with
  40 http://en.wikipedia.org/wiki/Virtualization_Technology#Intel_virtualization_.28VT-x.29[Intel
  41 Virtualization Technology (Intel VT-x)] support. (http://ark.intel.com/search/advanced/?s=t&VTX=true&InstructionSet=64-bit[List of processors with Intel VT and 64-bit])
  42
  43 Supported AMD CPUs::
  44
  45 64-bit processors with
  46 http://en.wikipedia.org/wiki/Virtualization_Technology#AMD_virtualization_.28AMD-V.29[AMD
  47 Virtualization Technology (AMD-V)] support.

  49 What is a container, CT, VE, Virtual Private Server, VPS?::
  50
  51 Operating-system-level virtualization is a server-virtualization
  52 method where the kernel of an operating system allows for multiple
  53 isolated user-space instances, instead of just one. We call such
  54 instances containers. As containers share the Kernel they are
  55 limited to Linux guests.
  56
  57 What is a QEMU/KVM guest (or VM)?::
  58
  59 A QEMU/KVM guest (or VM) is a guest system running virtualized under
  60 {pve} using QEMU and the Linux KVM kernel module.
  61
  62 What is QEMU?::
  63
  64 QEMU is a generic and open source machine emulator and
  65 virtualizer. QEMU uses the Linux KVM kernel module to achieve near
  66 native performance by executing the guest code directly on the host
  67 CPU.
  68 It is not limited to Linux guests but allows arbitrary operating systems
  69 to run.
