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 | |
fb810903 DM |
24 | for 32-bit for the platform. |

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 | + | |

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]) | |

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 | |
92702cb2 TL |
54 | instances containers. As containers share the Kernel they are |
55 | limited to Linux guests. | |

a660560c | 57 | What is a QEMU/KVM guest (or VM)?:: |
fb810903 | 58 | |
a660560c DM |
59 | A QEMU/KVM guest (or VM) is a guest system running virtualized under |
60 | {pve} using QEMU and the Linux KVM kernel module. | |
fb810903 | 61 | |
a660560c | 62 | What is QEMU?:: |
fb810903 | 63 | |
a660560c DM |
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. | |
92702cb2 TL |
68 | It is not limited to Linux guests but allows arbitrary operating systems |
69 | to run. |
