1.1.1. Requirements for Standalone Installations

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

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

    Note

    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 GB (at least 32 GB 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.
