During the installation or upgrade of MediaCP you might receive the following notice:
ERROR: Your system is not supported due to OpenVZ virtualization.
A VPS (Virtual Private Server) uses several virtualization technologies to provide its virtual environment.
OpenVZ is an operating system-level virtualization based on a modified Linux kernel, and provides a modified version of CentOS or Debian. OpenVZ CentOS or Debian is not a real version of the operating system and is not supported by several technologies required to operate the MediaCP.
You should purchase a VPS that uses hardware virtualization such as KVM, VMWare or another. We suggest a provider such as Vultr, OVH or Amazon.
