Starting CHARON Virtual Machine Manager

CHARON execution is controlled by the "CHARON Virtual Machine Manager" that manages each CHARON instance, called a "CHARON Virtual Machine", running on the host.

The CHARON installation procedure creates a shortcut on the desktop and under the Windows Start menu for the CHARON Virtual Machine Manager.

Desktop shortcut:

"Start" menu shortcut:

The CHARON Virtual Machine Manager runs automatically at Windows startup. If it is minimized to tray, it can be re-opened in the following way:

After clicking the icon, the CHARON Virtual Machine Manager window appears.

Creating a CHARON Virtual Machine

Creating a CHARON VM using provided templates

CHARON installation contains a set of template files for creating a base configuration for each AXP model. Once the CHARON Virtual Machine (VM) is created using these templates it can be configured further to meet your requirements and all the specifics of the emulated system.

Start the CHARON Virtual Machine Manager (see above) and press the "Create VM from Template" button:

In the dialog window that appears select the Alpha hardware model:

Note the Home Directory for the VM (see screenshot below), it will be used by default for storing logs, virtual disk images, toy and container files if no path is specified in the configuration file.

Specify a name for the VM and press the "Create" button:

The CHARON Virtual Machine Manager will report the VM has been created successfully:

It will then appear in the left pane:

Creating a CHARON VM using an existing configuration file

It is also possible to use an existing configuration file for creating a CHARON Virtual Machine.

Open the CHARON Virtual Machine Manager (see above) and press the "Add Existing VM" button:

In the dialog window that appears select the target configuration file by clicking the "Browse" button:

Select the configuration file and click the "Open" button:

Enter the CHARON Virtual Machine name and note the "Home directory" for this VM, it will be used by default for storing logs, virtual disk images, toy and container files if no path is specified in the configuration file.

Press the "Create" button:

The CHARON Virtual Machine Manager will report the VM has been created successfully:

It will then appear in the left pane:

Running a CHARON Virtual Machine

Select the target CHARON VM in the left pane and press the "Start" button:

The CHARON Virtual Machine Manager will display the execution log:

 Note the color meaning:

The console of this particular CHARON VM will then appear (if defined in the configuration file):

Depending on settings, Windows may display a Firewall warning dialog asking to confirm CHARON access to different networks.

Check the desired options and press the "Allow access" button.

Stopping a CHARON Virtual Machine

Stopping a running emulator is the equivalent of using the power-switch to power off a running physical Alpha – if you do this while an operating system is running, you risk data corruption and loss. Thus you should always shut down the Tru64 UNIX/OpenVMS guest before powering off the emulator, if possible. Powering off the emulator while the guest is still running should be the last resort after all attempts to shut the guest down have failed.

Select the target CHARON VM in the left pane and press the "Stop" button. A dialog will appear to confirm, select "Yes" to continue to stop the VM:

Removing a CHARON Virtual Machine

To remove a CHARON VM, select it and pressing the "Remove VM" button:

The Virtual machine must be stopped before removing it (see Running and managing CHARON-AXP for Windows#Stopping a CHARON Virtual Machine chapter above).

A confirmation dialog will be displayed:

Press the "Remove" button and confirm the CHARON VM removal by pressing the "Yes" button:

Modifying a CHARON Virtual Machine

Select the target CHARON VM and switch to the "VM Configuration" tab to see its features:

750

Using this dialog it is possible to:

• Explore the Home Directory of the CHARON VM.
• Create virtual disks by pressing the "Create Virtual Disks" button.
• Edit the CHARON VM configuration file.
  
• Change the startup mode.
• Select the CHARON version used for this Virtual Machine.

Exploring CHARON Virtual Machine Home Directory

Press the "Explore" button to open up a Windows Explorer window showing the content of the selected CHARON VM home folder:

This content includes the CHARON VM configuration file and may also include virtual disks and tapes images, logs, ROM files, etc.

Making a new virtual disk

It is very convenient to use the "Create Virtual Disk" button to create empty disk images in the CHARON VM Home Directory:

The MkDisk utility will be started for this operation:

Refer to the "Utilities" section of this User's Guide for more information about the MkDisk utility.

CHARON Virtual Machine configuration file

Press the "Edit Configuration file" button:

Alternatively it is possible to select the target CHARON VM and press the "Edit Configuration" button:

The configuration file specifies all the settings of the CHARON VM. This will be discussed in the next chapter.

CHARON Virtual Machine startup mode

By default, the CHARON VM startup mode is set to "Manual" meaning a user has to start the CHARON VM manually using the CHARON Virtual Machine Manager after a host reboot. If the CHARON VM has to start automatically, select the "Automatic" option.

Setting the mode to "Automatic" will only start the CHARON VM, it will not boot the operating system. This part will be discussed in the next chapter.

Select the CHARON VM startup behavior in the "Startup type" drop down list:

CHARON version to be used for CHARON VM

The CHARON installation procedure allows several versions of CHARON to be installed on the host at the same time (V4.8 and later only). This option can be used for testing.

If a patch has been applied to a specific version, only the patched version will appear. If you need to roll back to the previous version, please uninstall the patch according to the documentation provided with the patch.

Select the target CHARON version from the "Executable" drop-down list and press the "Apply" button:
