Function

The virtual-system command creates a virtual system (VS) or displays the view of a created VS.

The undo virtual-system command deletes a specified VS.

The default VS on a PS is Admin-VS.

Usage Guidelines

Usage Scenario

Each PS has its own main boards (MBs) and line cards (LCs). To fully utilize hardware resources and share slot resources, a PS can be partitioned into several virtual systems (VSs). To create VSs on a physical system (PS), run the virtual-system command.

Configuration Impact

After having been created on a PS, VSs can share the same system software but different service protocols, such as Border Gateway Protocol (BGP) and Open Shortest Path First (OSPF). Each VS has its own configuration management system and routing protocols.

Follow-up Procedure

A VS is a system with simulated software and hardware. VSs share all resources, such as IPU, not physical and logical interfaces. VSs can be working properly only after they are assigned slot and interface resources.

To assign slot resources to a VS, run the virtual-system command.

To assign interface resources to a VS, run the assign interface command in the VS view.

Precautions

After a VS is created, a device automatically creates Admin-VS. Admin-VS cannot be manually created or deleted.
If Admin-VS is reset, all other VSs that are managed by Admin-VS will be automatically reset.
The VS slot resources can be allocated only by The PS administrator. The same slot resources can be allocated to multiple VSs.
The slot resources deleted from a VS are automatically allocated to The Admin-VS, and The Admin-VS takes over services carried using these slot resources.
a newly created VS does not have any configuration. Therefore, you need to manually configure it. If you want to load another configuration file for The VS, ensure that The interfaces in The configuration file are in one-to-one mapping with The interfaces of The VS.
If The specified virtual device is deleted using The undo virtual-system VS-name command, The configuration associated with The VS is also deleted.
VS names are case-insensitive when being created. For example, if a VS named AAA has been created, you cannot create a VS named aaa. After a VS is created, the name of the VS is case-sensitive when being used.

Example

# Create a VS named vs1.

<HUAWEI> system-view
[~HUAWEI] admin
[~HUAWEI-admin] virtual-system vs1
