4.5 Configuring a Virtual Machine by Modifying its xend Settings

You can modify a virtual machine’s settings by modifying its xend configuration information. A virtual machine’s configuration information is stored in the xend database and can be exported to a file, modified to meet your specific virtualization requirements, and then re-imported back into the xend database.

  1. In a terminal on the management virtual machine desktop, enter xm list -l name > filename to export a virtual machine’s settings from xend to a file.

    • name is the virtual machine name

    • filename is the name you specify as the filename

  2. Use a text editor to make and save any desired changes.

  3. At the command line, enter xm new -F filename to import the new settings into the xend database.

  4. Enter xm start vm_name to start the virtual machine with the new settings.

NOTE:It is no longer recommended that you edit the initial creation files stored in etc/xen/vm, which are used only during the creation of a new virtual machine.
