What license does the {pve} project use?::

{pve} code is licensed under the GNU Affero General Public License,
version 3.

Will {pve} run on a 32bit processor?::

{pve} works only on 64-bit CPU´s (AMD or Intel). There is no plan
for 32-bit for the platform.
+
NOTE: VMs and Containers can be bothe 32-bit and/or 64-bit.

Does my CPU support virtualization?::

To check if your CPU is virtualization compatible, check for the "vmx"
or "svm" tag in this command output:
+
----
egrep '(vmx|svm)' /proc/cpuinfo
----

Supported Intel CPUs::

64-bit processors with
http://en.wikipedia.org/wiki/Virtualization_Technology#Intel_virtualization_.28VT-x.29[Intel
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])

Supported AMD CPUs::

64-bit processors with
http://en.wikipedia.org/wiki/Virtualization_Technology#AMD_virtualization_.28AMD-V.29[AMD
Virtualization Technology (AMD-V)] support.

What is a container, CT, VE, Virtual Private Server, VPS?::

Operating-system-level virtualization is a server-virtualization
method where the kernel of an operating system allows for multiple
isolated user-space instances, instead of just one. We call such
instances containers.

What is a QEMU/KVM guest (or VM)?::

A QEMU/KVM guest (or VM) is a guest system running virtualized under
{pve} using QEMU and the Linux KVM kernel module.

What is QEMU?::

QEMU is a generic and open source machine emulator and
virtualizer. QEMU uses the Linux KVM kernel module to achieve near
native performance by executing the guest code directly on the host
CPU.
