Supported VOS3000 Versions on CentOS7

VOS3000 versions that officially work on CentOS7 x64:

VOS3000 2.1.8.0

VOS3000 2.1.8.05

VOS3000 2.1.9.07

Many modern datacenters no longer provide CentOS7 directly from their OS templates, so manual installation is required. (CentOS7 Installation for VOS3000)

Datacenter Installation Reality (ISO / IPKVM / Image)

Different datacenters provide different installation methods:

IPKVM access (Hetzner, OVH)

ISO mounting support

Cloud-only formats like IMG, QCOW2, RAW (DigitalOcean, some cloud vendors)

CentOS7 is mandatory for VOS3000, even though CentOS7 is now officially EOL.

CentOS7 EOL – Is It Unsafe for VOS3000?

CentOS7 is End-of-Life, which means:

No new feature development

No official package updates

This does NOT mean CentOS7 is insecure.

After installation, repositories must be updated properly to vault repositories to download required packages.

We are still running:

CentOS7

Even CentOS5 in some legacy environments

VOS3000 is isolated Additional firewall rules are applied No unnecessary services are exposed

So there is no real production risk if configured properly. (CentOS7 Installation for VOS3000)

Can VOS3000 Run on CentOS9, CentOS10, Debian or Ubuntu?

No.

VOS3000 is designed specifically for CentOS:

CentOS6 – Supported

CentOS7 – Recommended

CentOS8.2 – Works only for 2.1.9.07 (not recommended)

Debian – Not supported Ubuntu – Not supported CentOS9 / 10 – Not supported

CentOS7 remains the safest production OS for VOS3000.

Recommended CentOS7 ISO for VOS3000

Use the official CentOS vault ISO:

CentOS-7-x86_64-Minimal-2009.iso

Minimal version Clean system Best performance for VOS3000

Kernel & Repository Warning

Wrong kernel may cause kernel panic

Use correct kernel only for VOS3000

Repository configuration must be accurate after CentOS7 EOL. (CentOS7 Installation for VOS3000)
