Hosts


Host: embraces computers included in the virtual platform. Hosts provide computing resources (CPU and RAM) to the platform.

flexVDI Dashboard lets you see the Hosts that have been registered in the flexVDI Manager with the configuration command flexvdi-config. Registered Hosts will be displayed in the left area of the main window of flexVDI Dashboard. It will also display which Host is the one executing the flexVDI Manager:


flexVDI Dashboard shows more detailed information about Hosts. This information is shown in the right side of the main window of the flexVDI Dashboard.

The following operations can be performed on a Host fromflexVDI Dashboard:

  • Modifying a Host
  • Disable: When a Host is disabled it changes to "maintenance mode" and stops being available to any Pool to run Guests on it.
  • Enable: Finish the "disabled state", of the Host, and changes it to the regular state.
  • Unregister: Takes the Host out of the control of the current flexVDI Manager. The Host is now ready to take part of another flexVDI platform.
  • Shutdown.

Guest


Guest: virtual machines created from flexVDI Manager.

Related tasks:

  • Create a new Guest
  • Change the boot device of a Guest: allows the Guest to boot from its virtual disk, a virtual CD, or from network.
  • Start a Guest: the flexVDI Manager will ensure that the selected Guest will start the operation is requested, and it will also restart after a shutdown.
  • Start once a Guest: to boot the Guest once, without automatic restart.
  • Send shutdown to a Guest: equivalent to pressing the power button on a physical machine. OS will receive an ACPI shutdown request and will stop the machine tidily
  • Force stop of a Guest: is the virtual equivalent of shutting down the power source of the machine. The Guest will lose the information not saved in the moment of the shutdown, and can produce file system errors.
  • Pausing a Guest
  • Resuming a Guest
  • Suspending a Guest
  • Restoring a Guest
  • Modifying a Guest. This option allows to change the virtual hardware of a Guest.
  • Insert tools: inserts a virtual CD in the Guest with flexVDI Guest Tools installation software.
  • Changing the Media
  • Copying a Guest
  • Convert a Guest into a template.
  • Migrate a Guest
  • Migrate flexVDI Manager: in the left area of the main window, the flexVDI Manager is shown under one of the Hosts indicating where it is running. This instance behaves like a Guest; if for some reason the Host that executes it needs to be disabled or off, flexVDI Manager can migrate to another Host. In the context menu on the flexVDI Manager icon, click "Migrate" and select the destination host. Previously it is required to have completed the flexVDI Manager clustering configuration with flexvdi-config.
  • Open Guest Console
  • Delete a Guest
  • Convert a template into a Guest.

Pool


Pool: group of Guests. Pools reserves the Hosts resources for the Guests included in them.

Image Storage


Image Storage: it is a logical unit of storage. Image Storages are created in a set of Hosts that are selected during its creation. It can be seen as a Volume container, or as a storage for image disks.

Volume: they are created using the physical disks defined in the father Image Storage. Guest are stored in the Volumes.
