Note

  • This request requires direct access to the Appliance Manager API

  • Make a backup of your template folder before you begin

Info

If you are replacing a disk that was created from an instance of a captured VM, add an Abiquo OVF file to the original VM template folder before you upload your new disk.

Warning

The Appliance Manager API does not validate the request, so be sure to provide the correct path to your disk file or you could overwrite some other part of your file system!!

Here is an example use case

...

  1. Get the template details from the Abiquo API

  2. Create the replacement data object

  3. Replace the file using the Appliance manager API

...

2. Initial steps and requirements

Before you begin:

  1. Make a backup of your template folder

  2. If you are replacing a disk that was created from an instance of a captured VM, you must add an Abiquo OVF file to the original VM template folder.
    If you have a similar template created from an uploaded OVA file, you may be able to copy the OVF file and modify it for your template.

...

3. Log in to the API and obtain a token

If you wish to use token authentication, which is more secure and required for 2FA, do these steps.

To obtain an authorization token, send a GET request to the API login resource.

Use basic authentication and get the token from the X-Abiquo-Token header.

Code Block
curl --verbose -X GET "https://abiquo.example.com:443/api/login" -u adminuser:password -k

...

Now you can get the token from the X-Abiquo-Token header of the response.

In your API requests, use the token in a header with the following format. In this example we have shortened the token. In the workflow below, we represent the token with {api_token}.

...

Tip

You can also get the token from the UI! Go to the browser Developer console on the Network tab and in the request responses look for the X-Abiquo-Token header.

...


4. Get the template details

Get the enterprise, for example, by using the "has" parameter to filter by a text string in the enterprise names from the list enterprises request.

Replace the base_api_url with the URL of your Abiquo API server, for example, https://abiquo.example.com/api, and replace {api_token} with the token from the X-Abiquo-Token response header.

Here we use JQ to filter the API response to only display the enteprise enterprise names and IDs.

Code Block
curl -X GET '{base_api_url}/admin/enterprises?has=Abiquo' \
     -H 'Accept: application/vnd.abiquo.enterprises+json;version=6.1' -k \
     -H 'Authorization: Token {api_token}' \
     | jq '.collection[]| {name: .name, id: .id}'

...

If you are not already working with the selected enterprise, switch enterprise in the UI (by clicking the Switch enterprise button) or by switching enterprises via the API.

...

Get the link to the enterprise's datacenter repository for the appropriate datacenter. The link to the datacenter repositories can be found in the Enterprise entity.

Code Block
{
  "title": "repositories",
  "rel": "datacenterrepositories",
  "type": "application/vnd.abiquo.datacenterrepositories+json",
  "href": "{base_api_url}/admin/enterprises/1/datacenterrepositories"
}

...

Code Block
curl -s -X GET '{base_api_url}/admin/enterprises/1/datacenterrepositories' \
     -H 'Accept: application/vnd.abiquo.datacenterrepositories+json;version=6.1' -k \
     -H 'Authorization: Token {api_token}' \
     | jq '.collection[].links[]| select(.rel=="datacenter", .rel=="edit")'

The JQ filter above will print the datacenter and edit links for each of the datacenter repositories.

...

Select the appropriate repo and then use the edit link to get the datacenter repository and select the link to the virtual machine templates.

...

Get the templates, and find the appropriate template. You can use the "has" parameter to search for the template by name.

...

Get the template that you wish to use. The template will contain a link to the template template’s disks.

Code Block
curl -s -X GET '{base_api_url}/admin/enterprises/1/datacenterrepositories/1/virtualmachinetemplates/72' \
     -H 'Accept: application/vnd.abiquo.virtualmachinetemplate+json;version=6.1' -k \
     -H 'Authorization: Token {api_token}' \
     | jq '.links[] | select (.rel=="disks")'

From the JQ filter in the above example, we got the following disk link.

Code Block
{
  "title": "disks",
  "rel": "disks",
  "type": "application/vnd.abiquo.disks+json",
  "href": "{base_api_url}/admin/enterprises/1/datacenterrepositories/1/virtualmachinetemplates/72/disks"
}

...

For the repository, you will need the diskUrl and currentPath of this disk. In the Abiquo API, these are the href URL from the disk edit disk edit linkand the pathof thedisk.

The above query and JQ filter returned the following.

Code Block
{
  "title": "disk",
  "rel": "edit",
  "type": "application/vnd.abiquo.disk+json",
  "href": "{base_api_url}/admin/enterprises/1/datacenterrepositories/1/virtualmachinetemplates/72/disks/74"
}
{
  "sequence": 0,
  "path": "1/bundle/e05785d2-b49a-4034-9bb9-3440e1693589-4ba3b6e1-6f06-47d9-8703-9e9/4ba3b6e1-6f06-47d9-8703-9e9eae1c2a9b-snapshot-yVM2b8c91aa4-14b1-44a6-b27b-aa12c7ca3433-flat.vmdk"
}


You will need the “href” href and the “path” path for the replacement object!

...

5. Create the replacement object

From the above response, we need

  • the href URL from the disk disk in the edit link

  • the pathof thedisk

From the example above, for the first disk with a sequence a number of "0", we have the following.

Code Block
"href": "{base_api_url}/admin/enterprises/1/datacenterrepositories/1/virtualmachinetemplates/72/disks/74"
"path": "1/bundle/e05785d2-b49a-4034-9bb9-3440e1693589-4ba3b6e1-6f06-47d9-8703-9e9/4ba3b6e1-6f06-47d9-8703-9e9eae1c2a9b-snapshot-yVM2b8c91aa4-14b1-44a6-b27b-aa12c7ca3433-flat.vmdk"

...

From the above response, you will need to set the following

  • diskUrl = the href URL from the disk edit link

  • currentPath = path

To get the VM template URL, just remove the “disksdisks/XX” XX from the end of the diskUrl!

Here is an example object.

Code Block
languagejs
{ 
    "virtualMachineTemplateUrl":"{base_api_url}/admin/enterprises/1/datacenterrepositories/1/virtualmachinetemplates/72",
    "diskUrl":"{base_api_url}/admin/enterprises/1/datacenterrepositories/1/virtualmachinetemplates/72/disks/74",
    "currentPath":"1/bundle/e05785d2-b49a-4034-9bb9-3440e1693589-4ba3b6e1-6f06-47d9-8703-9e9/4ba3b6e1-6f06-47d9-8703-9e9eae1c2a9b-snapshot-yVM2b8c91aa4-14b1-44a6-b27b-aa12c7ca3433-flat.vmdk",
	"diskController": "lsilogic",
	"diskControllerType": "SCSI",
    "diskFileFormat":"VMDK_STREAM_OPTIMIZED",
	"diskFilePath": "",
	"label": "Hard disk 1",
    "requiredHDInMB":120,
    "sequence":0
}


Note

For the "requiredHDInMB" you must enter the correct capacity or deployed size of the disk. The capacity value is stored in the disk file itself.

See Determine the size of a VM disk file

Abiquo does not validate the value that you enter and if you enter an incorrect value, the platform will try to deploy the disk with its true capacity. The deploy may fail and the platform will not be able to properly check that the disk will fit on the hypervisor datastore.

Important note: You cannot resize (expand) a boot disk before you deploy a VM. After you expand any disk, remember to update the configuration of the disk in the VM operating system.

...

Note

The default value for the diskControllerType is "IDE" and the default value for the diskController is NULL.

If your template uses a different controller type and value, such as "SCSI" and "lsilogic", you must add these values in the diskReplace.json entity, as shown above. If you do not add them, the platform will overwrite your template with its default values.

You should note that the AM API does not support all of the values that are supported by the Abiquo API.

...


...


6. Obtain the URLs to replace the file

Obtain the URLs to build the request to replace the disk.

Warning

If your file name or folder name contains spaces, do the steps below in “Steps for folder names with spaces” and “Steps for file names with spaces” to obtain the folder path, file name and URL

...

For template folder, from our example with the following “href” href and “path” path:

Code Block
"href": "{base_api_url}/admin/enterprises/1/datacenterrepositories/1/virtualmachinetemplates/72/disks/74"
"path": "1/bundle/e05785d2-b49a-4034-9bb9-3440e1693589-4ba3b6e1-6f06-47d9-8703-9e9/4ba3b6e1-6f06-47d9-8703-9e9eae1c2a9b-snapshot-yVM2b8c91aa4-14b1-44a6-b27b-aa12c7ca3433-flat.vmdk"

...

So the full URL to post to will be template path containing the prefix “ /am/erpos/{enterpriseId}/templates and the folder path

Code Block
/am/erepos/1/templates/1/bundle/e05785d2-b49a-4034-9bb9-3440e1693589-4ba3b6e1-6f06-47d9-8703-9e9
Tip

The template path does not contain the ID of the datacenter repository. It contains the folder name from /opt/vm_repository.
So in our example, the datacenter repository ID is 1 and the path is "1/bundle.." but they are not related

Info

If the original disk file is not available, you can create a placeholder file in the folder using the touch command, in the format touch {currentPath}. For example:
touch 1/bundle/e05785d2-b49a-4034-9bb9-3440e1693589-4ba3b6e1-6f06-47d9-8703-9e9/4ba3b6e1-6f06-47d9-8703-9e9eae1c2a9b-snapshot-yVM2b8c91aa4-14b1-44a6-b27b-aa12c7ca3433-flat.vmdk

Steps to

...

obtain the URL for folder names with spaces

The URL to post to contains the enterprise ID and the template folder in the following format.

...

The template folder is the folder path on the NFS Repository, without the file name.

So for a folder name with spaces, for example, “abc def” abc def.

We would have the following “href” href and “path” path:

Code Block
"href": "{base_api_url}/admin/enterprises/1/datacenterrepositories/1/virtualmachinetemplates/72/disks/74"
"path": "1/bundle/abc%20def/olddisk-flat.vmdk"

...

The format of the URL to post to must encode the special characters in the folder path again. So for our example:

Code Block
/am/erepos/1/templates/1/bundle/abc%2520abc

...

Code Block
curl -v -k -X POST "https://remoteservices.example.com:443/am/erepos/1/templates/1/bundle/abc%2520abc"

...

7. Replace the disk

This request is to the Appliance Manager remote service, so we need to use its URL.

...

We recommend that you use double quotation marks around all the parameters, including the file parameters for diskInfo and diskFile.

Code Block
curl -v -k -X POST '{base_url_NO_API}/am/erepos/1/templates/1/bundle/e05785d2-b49a-4034-9bb9-3440e1693589-4ba3b6e1-6f06-47d9-8703-9e9' \
  -H 'Authorization: Token {api_token}' \
  -F "diskInfo=@diskReplace.json" -F "diskFile=@newdisk.vmdk"

Replace newdisk.vmdk  with the name of your disk file on the local file system.

Save the disk replacement object you created previously to a file calleddiskReplace.json. This is the real data object from our example.

...

Use double quotation marks around all the parameters, including the file parameters for diskInfo and diskFile, especially if the disk file name contains spaces!

...

Success status code: 201 Created

...

8. Check the disk file

You can check the disk file in Abiquo UI, which will display the path and file size.

...

You can also go to the datacenter repository on the NFS share (in the /opt/vm_repository folder) and check the new disk file on the file system using the details in the Location link in the above response.

...

Note that if the disk file had spaces, it would display with “+” marks signs in the file name, for example:

...

Which for our disk, shows the newdisk.vmdk file has been loaded into Abiquo.

...
