Requirements for Standalone Installations
-----------------------------------------

The recommended hardware requirements for running Virtuozzo 7 as a standalone installation are as follows:

-  x86-64 platform with hardware virtualization support: Intel VT-x (with "unrestricted guest"),

   .. note:: To check if the Intel processor supports the "unrestricted guest" feature: 1) Download ``vmxcap.py`` from https://github.com/qemu/qemu/blob/master/scripts/kvm/vmxcap, 2) Run ``python vmxcap.py | grep -i unrest``. The result must be ``yes``.

-  CPU: at least 4 cores, a 64-bit processor is required for running 64-bit guest operating systems,

-  RAM: 4 GB or more,

-  HDD: 64 GB or more,

-  SSD (optional): at least 30 GiB (at least 32 GiB with ``/boot``)

-  Network: an Ethernet network adapter and a valid IP address.

The actual number of virtual machines and containers you can run on a physical server and their performance depend on resources they will consume.
