CentOS is the best choice for OpenVZ to work properly.
The Hardware Node requirements for the standard 32-bit edition of OpenVZ are the following:
The computer should satisfy the Red Hat Enterprise Linux or Fedora Core hardware requirements.
i)IBM PC-compatible computer.
ii)CPUs: Intel Celeron, Pentium II, Pentium III, Pentium 4, Xeon, or AMD Athlon CPU. The more Virtual Private Servers you plan to run simultaneously, the more CPUs you need.
iii)Memory: Atleast 128 MB of RAM.The more memory you have, the more Virtual Private Servers you can run. The exact figure depends on the number and nature of applications you are planning to run in your Virtual Private Servers. However, on the average, at least 1 GB of RAM is recommended for every 20-30 Virtual Private Servers.
iv)HDD: Atleast 4 GB of free disk space. Each Virtual Private Server occupies 400-600 MB of hard disk space for system files in addition to the user data inside the Virtual Private Server (for example, website content). You should consider it when planning disk partitioning and the number of Virtual Private Servers to run.
v)NIC: Network card will be either Intel EtherExpress100 (i82557-, i82558- or i82559-based) or 3Com(3c905 or 3c905B or 3c595) or RTL8139-based are recommended.
A typical 2-way Dell PowerEdge 1650 1u-mountable server with 1 GB of RAM and 36 GB of hard drives is suitable for hosting 30 Virtual Private Servers.
