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:

  1. Log in to the tenant where the template was created

  2. In the Catalogue, edit the template, and go to Disks.

Add disks to VM templates

To change the boot order of a disk

  1. Click the pencil edit button near the Sequence number and enter a new number.  There must always be a boot disk in the 0 position, and the boot disk cannot be an empty 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

  2. Select one of the options: Disk from local file, Disk from iso file, Empty disk or Template disk.

  3. Enter the Details of the disk as described in the following sections

Add disk from local file

Enter the details of the disk to upload.

Create a disk from local file

Field

Value

Type

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

Capacity

For the Capacity enter the hard disk space that the hypervisor will need to deploy this disk in MB, GB, or TB.
To get the capacity of the hard disk, use the process described at Determine the size of a VM disk file. If you enter another value, the platform may ignore it or fail to deploy a VM.

  • For 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
if the user must select a datastore tier.

Allocation type

With appropriate privileges, you can modify this value in a VM before you 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 lsilogic

Name

The name of the disk

Add disk from ISO file

Enter the details of an ISO disk you will upload

Create a disk from an ISO file

Field

Value

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 this disk before they deploy

Add an empty disk

Enter the Capacity (or size) of the deployed disk and the disk Controller type and for SCSI disks, the Controller information.

Create an empty disk

Field

Description

Capacity

The deployed size of the hard disk the unit

Datastore tier

Only available for existing disks

Datastore tier will be required...

Select this checkbox to indicate that the user must select a datastore tier
while creating a VM.
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. 

Copy existing disks from a 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.

Edit template

Edit a template disk

 To edit a disk:

  1. Select the Disk

  2. Click the pencil Edit button and make changes as described below

Edit virtual machine template disk

Field

Description

Type

The disk type of the template.
If the type is incorrect or UNKNOWN, you cannot deploy a VM with the disk.
See Template compatibility table

Capacity

For the Capacity enter the hard disk space that the hypervisor will need to deploy this disk in MB, GB, or TB.
To get the capacity of the hard disk, use the process described at Determine the size of a VM disk file. If you enter another value, the platform may ignore it or fail to deploy a VM.

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

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

Capacity units

MB, GB, or TB

File name

To download the disk, click Download beside the file name

Datastore tier

To set the storage service level of the template disk, select a Datastore tier. You can modify this value in a VM before you deploy it

Datastore tier will be required
while creating a virtual machine

Optional.
The user will require privileges to select a datastore tier to create a VM

Allocation type

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

Controller type

If you change the controller type your VM may not boot.
The user can modify this value after they create a VM and before they deploy it.

Controller

On ESXi for SCSI

  • You can use multiple controllers on a VM and you can change the
    controller, even after deploy

  • The default value is lsilogic or a value set by the system administrator

See Template disk controllers for SCSI

Name

Hard disk name

Replace a template disk

To upgrade a VM template operating system so users automatically deploy the new version, you can replace a template disk with an upgraded disk from your local file system.

  1. Edit the VM template and select the disk

  2. Click the double arrow disk replace button

    Replace a VM template disk

  3. Select the correct Type. If the type is incorrect or UNKNOWN, you cannot deploy a VM with the disk.
    See Template compatibility table

  4. For the Capacity enter the hard disk space that the hypervisor will need to deploy this disk in MB, GB, or TB.
    To get the capacity of the hard disk, use the process described at Determine the size of a VM disk file. If you enter another value, the platform may ignore it or fail to deploy a VM.

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

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

  5. Click Select file and browse to find your file

  6. Click Save

The platform will upload the disk and update it in the catalogue.

Replacing a VM template disk

If you are replacing a disk with a long filename, the platform may remove part of the filename, but it should still be possible to deploy a VM from the VM template

Delete a template disk

Before you begin, check that the template is not in use. A template is in use if it has deployed VMs or dependent instances. 

To delete a template disk:

  1. Select the Disk to delete

  2. Click the delete trash can icon
