Virtual Automation (PVA) is a flexible and easy-to-use administration tool designed for managing physical servers with Virtuozzo Containers or Parallels Server Bare Metal or Parallels Cloud Server software. With PVA, you can create groups of physical servers and perform both collective and individual administration operations on these groups. Moreover, you can manage the virtual environments residing on the registered physical servers: their productivity and resources, system tasks and processes, configuration, and much more.

When PVA MN cannot reach the virtualization node over the network, an attempt to register a new node will fail with:
An error occurred during the registration. Please verify the server address and user credentials Failed to register the physical server. Make sure that it has PVA Agent for Virtuozzo or for Parallels Server installed and is accessible via the network.
- If the new node registration stuck on "Connecting to Hardware Node":
