1.1. Requirements for Standalone Installations¶
The recommended hardware requirements for running Virtuozzo Hybrid Server 7 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).
To check if the Intel processor supports the “unrestricted guest” feature: 1) Download
vmxcap.pyfrom https://github.com/qemu/qemu/blob/master/scripts/kvm/vmxcap, 2) Run
python vmxcap.py | grep -i unrest. The result must be
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. See Partitioning the Hard Drives for details.
SSD (optional): at least 30 GiB (at least 32 GiB with
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.
