Modify VM template disks

 

This page describes how to add disks to your VM templates as part of the process to Modify a VM template in private cloud

 

To create VMs more quickly and save space on your NFS server, you can add empty disks to your VM templates.
When users deploy VMs, the platform will create these disks directly on the hypervisor datastore.
See the section below on Add an empty disk!

 

Edit VM template disks

To edit VM template disks in private cloud, log in to the tenant that the template belongs to, edit the template, and go to Disks.

Add disks to VM templates

 

To change the boot order of a disk

To download a disk

  1. Select the disk

  2. Click the Download symbol on the right-hand side of the disk details

To add a disk:

  1. Click the + Add button in the top right of the Disk dialog

To use the disk in the platform, it must have a correct type (not Unknown).
If you have not added any hypervisors yet, the V2V conversion process will generate conversions for ALL supported hypervisors

Capacity

The hard disk size required for the deployed disk in MB, GB, or TB. See Determine the size of a VM Disk File.

  • Fixed formats, the capacity is the physical size of the template disk.

  • For sparse and compressed formats, the capacity is the provisioning size.

File name

Click Select file and use your browser to choose the file to upload.

Require DS tier

Select Datastore tier will be required when creating a virtual machine to ensure that the user will select a datastore tier.

Allocation type

The user with appropriate privileges can modify this value in a VM before they deploy it

Controller type

Select a controller type from: IDE, SCSI, SATA (ESXi), and VIRTIO (KVM)

Controller

On ESXi you can enter a SCSI controller type. The default value is the lsilogic controller.

Name

The name of the disk

Add disk from ISO file

Enter the details of an ISO disk you will upload

Field

File name

Click Select file and use your browser to choose the file to upload

Datastore tier will be required while creating a virtual machine

Optionally select this checkbox to require the user to select a datastore tier. To create a VM, the user will require the privilege to Manage virtual machine hard disks

Controller type

Recommended controllers for ISO disks are SATA or IDE

Controller

For SCSI controllers only

Name

The name of the disk

Add an extra empty disk

If you enter a disk size, the platform will create this hard disk and use it to install the ISO.
Users can change the size of the disk before they deploy a VM


Add an empty disk

The user will require the privilege to manage hard disks in order to create a VM

Allocation type

Optional. Allocation type of the disk.

Controller type

The controller type of disk

Controller

Optional for SCSI controllers only. See Template disk controllers for SCSI

Name

The name of the hard disk

 

When you deploy the VM, the platform will create the empty disk on the hypervisor datastore.


Add a template disk

Select a template from the Catalogue and then select a disk from the template. 

Abiquo will select the original disk, not the conversions. If you require other formats, generate conversions for these formats. 


Manage template disk conversions

  • To display and manage disk conversions, go to Disks, select the disk and check the conversion details in the Selected disk conversions panel.

  • To manually launch conversions to template formats, click Generate missing conversions. The platform will create conversions for any new hypervisor types.

  • To restart a failed conversion, click the Restart conversion link beside the conversion.

File name

To download the disk, click Download beside the file name

Datastore tier
