Agent configuration settings


VirtualBox Path

    This is the location of the VirtualBox binaries on the Host.

Agent Name

    This is the hostname of the Host that the Agent software is installed on.

Host Group Name

    This is the name of the Host Group that the agent belongs to. Images assigned to this group can be run on this Host.

Server List

    This is the list of Infinity servers known by the agent. If there are multiple servers configured and the server the Agent is logged into fails to respond, the Agent will automatically attempt to connect to the other servers in the list. The Agent regularly polls its server to detect failure.

Backup Directory

    This is the location the Agent will write VM backups too. The agent will execute preBackup and postBackup scripts if they exist. The scripts must be located in the backup directory.  preBackup is run as "preBackup <backup file name> <VM name>".  postBackup is run as "postBackup <backup file name> <VM name> <backup job status>".

Possible backup job status messages are "Completed", "Cancelled" or "Error".

Login ID and Password

    If the Login ID and password are set, on Agent start up, the Agent will use these settings to automatically login.

If the login fails, the Agent will display the login dialog.

Log Level

    This sets the Agents logging Level. INFO is the default level. For debugging purposes, the Agent can be configured to log more details. All logs all messages.

When the Log Level is set to ALL, the VirtualBox configuration for VMs will not be removed as usual when a VM is powered off to allow the use of VirtualBox tools to help debug VM issues.

Agent Interface

    This is the network card the Infinity server will contact the Agent on.

Bridged Interface

    VMs configured to use Bridged Interfaces will be connected to this NIC

Audio Support

    VMs configured with audio support will use this facility on the Host to produce sound.

RDP Command

    If the user attempts to make an RDP connection to a remote VM, By default the built in Java RDP client will be used.

You can configure the Agent to use another program instead by entering the command here.

Variables %username, %password, %address and %port are supported.

For example: mstsc /v:%address:%port


    Maximum Host RAM used by VMs. A cap of zero means that there is no cap on RAM, VMs can use all RAM available on the Host. Setting it higher than the Hosts actual amount of ram will allow the running of more VMs but could lead to problems if the VMs actively use all the RAM configured to them.


    If Headless is enabled, VMs will be started on the host in the background. VM access will be remote only.

Full Screen

    VMs will be started in full screen mode.


    3D acceleration will be available on all VMs. If the 3D checkbox is greyed out, 3D support is not available on this Host.

To take advantage of 3D support, the VMs must have the VirtualBox utilities installed with 3D support enabled in the VM.

Use Host Cache

    By default the VirtualBox will not cache disk IO between the Host and the Infinity server but this option can be enabled.


    In Kiosk mode, VMs will be started in full screen and access the the VirtualBox tools will be disabled. But if the VM is shut down, users will have access to the host system.

Host RDP

    By default the Agent configures VirtualBox to use Infinity accounts to control remote RDP access to the VMs running on the Host.

If Host RDP is enabled, the Agent will configure VirtualBox to use accounts on the Host system to authenticate RDP access to VMs.


Auto Reset

    When enabled, causes the Agent to restart VMs that fail. 


    The individual windows that are displayed on the desktop of the virtual machine can be mapped on the host's desktop, as if the underlying application was actually running on the host.


Page Fusion

    In a server environment running several similar VMs (e.g. with identical operating systems) on the same host, lots of memory pages are identical. Page Fusion technology is technique to efficiently identify these identical memory pages and share them between multiple VMs.


Page Fusion supports only on 64-bit hosts, and it is not supported on Mac OS X hosts. Page Fusion currently works only with Windows guests (2000 and later).
