Virtual Storage Configuration

Nov 20, 2012

Virtual machines created using the New VM wizard will have at least one virtual disk and the selected VM template may also include additional virtual disks. A VM can have up to seven virtual disks as well as a virtual CD-ROM.

You can add more virtual disks, remove virtual disks, and change the size and location of virtual disks from the Storage page in New VM wizard.

Option Description
Use these virtual disks Select this option to use the virtual disks listed.
  • To add more virtual disks, click Add and specify the name, size and location (SR); see Add virtual disks.
  • To delete a virtual disk, click Delete.
  • To move a virtual disk to a different SR, select it in the list and click Properties, then choose an SR from the Location list.
  • To make a virtual disk bigger or smaller, select it in the list and click Properties, then enter a new value in the Size box.
  • To change the name or description of a virtual disk, select it in the list and click Properties, then enter the new text.
Use storage-level fast disk clone This check box appears if any of the virtual disks in the template or snapshot you are using to create the new VM are on the same SR. Select the check box to use hardware-level cloning features for copying the disks from the template/snapshot to the new VM. Using storage-level fast disk clone allows new VMs to be created very quickly.

This option is only supported for VMs using remote NFS shared storage or local VHD-based storage.

Create a diskless VM that boots from the network If you selected the Boot from network option on the OS Installation media page earlier in the wizard, you can select this option to make the new VM a diskless VM.
