22 | Will {pve} run on a 32bit processor?:: | |
23 | ||
24 | {pve} works only on 64-bit CPU´s (AMD or Intel). There is no plan | |
fb810903 DM |
25 | for 32-bit for the platform. |

29 | Does my CPU support virtualization?:: | |
30 | ||
31 | To check if your CPU is virtualization compatible, check for the "vmx" | |
32 | or "svm" tag in this command output: | |
33 | + | |
34 | ---- | |
35 | egrep '(vmx|svm)' /proc/cpuinfo | |

50 | What is a container, CT, VE, Virtual Private Server, VPS?:: | |
51 | ||
52 | Operating-system-level virtualization is a server-virtualization | |
53 | method where the kernel of an operating system allows for multiple | |
54 | isolated user-space instances, instead of just one. We call such | |
8e4bb261 | 55 | instances containers. As containers use the host's kernel they are |
92702cb2 | 56 | limited to Linux guests. |

a660560c | 58 | What is a QEMU/KVM guest (or VM)?:: |
fb810903 | 59 | |
a660560c DM |
60 | A QEMU/KVM guest (or VM) is a guest system running virtualized under |
61 | {pve} using QEMU and the Linux KVM kernel module. | |
fb810903 | 62 | |
a660560c | 63 | What is QEMU?:: |
fb810903 | 64 | |
a660560c DM |
65 | QEMU is a generic and open source machine emulator and |
66 | virtualizer. QEMU uses the Linux KVM kernel module to achieve near | |
67 | native performance by executing the guest code directly on the host | |
68 | CPU. | |
92702cb2 TL |
69 | It is not limited to Linux guests but allows arbitrary operating systems |
70 | to run. |
