7. Managing Virtual Environments

Virtual environment is a generic term for containers and virtual machines. A virtual environment is created on the basis of a virtualization technology and can be managed via Virtuozzo Automator. Physical servers running Virtuozzo can host both containers and virtual machines.

You can find the list of all virtual environments hosted on servers registered in Virtuozzo Automator on the Infrastructure > Virtual Environments screen (see Viewing Virtual Environments Information). On this screen, you can either right-click a virtual environment and select an operation from the context menu or select multiple virtual environments and click an operation button on the toolbar above the list. Available operations include:

  • Create one or more virtual environments (New Virtual Environment):
  • Start/restart/stop the selected virtual environments (Start/Restart/Stop).
  • Pause the selected virtual environments (Pause). Pausing frees up the host CPU resources while the consumption of other resources remains the same.
  • Stop the selected virtual environments without executing shutdown scripts (Power Off). This operation is only available to users with administrative privileges in Virtuozzo Automator. It can be used, for example, if a virtual environment has become broken and cannot be shut down properly.
  • Suspend the selected virtual machines or Linux-based containers (Suspend). This operation is similar to putting a regular computer to sleep. The current virtual environment state (including the state of all running applications and processes) is saved to a special file on the host. After returning from the suspended mode, the virtual environment resumes operation from the same state it has been in before suspension.
  • Back up the selected virtual environments (Back Up).
  • Migrate the selected virtual environments to a physical server registered in Virtuozzo Automator (Migrate).
  • Clone the selected virtual environments (Clone).
  • Delete the selected virtual environments (Delete).
  • Configure the general settings of the selected virtual environments (Configure).
  • Convert the selected virtual machines to templates (Convert to template).
  • Clone the selected virtual environments to templates (Clone to template).

Note

  1. You can perform operations on multiple virtual environments only if they are based on the same virtualization technology.
  2. You can also perform operations on a single virtual environment from its summary screen accessible by clicking that virtual environment’s name.

The sections of this chapter describe operations on multiple virtual environments in more detail. For operations specific to containers or virtual machines, see Managing Containers and Managing Virtual Machines, respectively.
