1.1. Requirements for Standalone Installations¶

The recommended hardware requirements for running an alpha build of Virtuozzo Hybrid Server 9 as a standalone installation are as follows:

• x86-64 platform with hardware virtualization support: Intel VT-x (with “unrestricted guest”) or AMD Virtualization (tested only on AMD EPYC).

  Note

  To check if the Intel processor supports the “unrestricted guest” feature: 1) Download vmxcap.py from GitHub, 2) Run python vmxcap.py | grep -i unrest. The result must be yes.

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

• RAM: 4 GB or more.

• HDD: the minimal required disk size is the sum of the minimal /vz and root partitions, as well as the swap size:

  min_hdd_size = min_vz_size + min_root_size + swap_size
  

  Where min_root_size is 12 GiB, min_vz_size is 30 GiB, and swap_size depends on the RAM size.

• SSD (optional): at least 30 GiB (at least 32 GiB with /boot).

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

You can also install Virtuozzo Hybrid Server in a virtual machine with similar virtual hardware. Make sure that nested virtualization support is enabled in your hypervisor.
