Method: OvirtSDK4::VmsService#add

Defined in:: lib/ovirtsdk4/services.rb

#add(vm, opts = {}) ⇒ `Vm`

Creates a new virtual machine.

The virtual machine can be created in different ways:

From a template. In this case the identifier or name of the template must be provided. For example, using a plain shell script and XML:

#!/bin/sh -ex

url="https://engine.example.com/ovirt-engine/api"
user="admin@internal"
password="..."
curl \
--verbose \
--cacert /etc/pki/ovirt-engine/ca.pem \
--user "${user}:${password}" \
--request POST \
--header "Version: 4" \
--header "Content-Type: application/xml" \
--header "Accept: application/xml" \
--data '
<vm>
  <name>myvm</name>
  <template>
    <name>Blank</name>
  </template>
  <cluster>
    <name>mycluster</name>
  </cluster>
</vm>
' \
"${url}/vms"

From a snapshot. In this case the identifier of the snapshot has to be provided. For example, using a plain shel script and XML:

#!/bin/sh -ex

url="https://engine.example.com/ovirt-engine/api"
user="admin@internal"
password="..."
curl \
--verbose \
--cacert /etc/pki/ovirt-engine/ca.pem \
--user "${user}:${password}" \
--request POST \
--header "Content-Type: application/xml" \
--header "Accept: application/xml" \
--data '
<vm>
  <name>myvm</name>
  <snapshots>
    <snapshot id="266742a5-6a65-483c-816d-d2ce49746680"/>
  </snapshots>
  <cluster>
    <name>mycluster</name>
  </cluster>
</vm>
' \
"${url}/vms"

When creating a virtual machine from a template or from a snapshot it is usually useful to explicitly indicate in what storage domain to create the disks for the virtual machine. If the virtual machine is created from a template then this is achieved passing a set of disk_attachment elements that indicate the mapping:

<vm>
  ...
  <disk_attachments>
    <disk_attachment>
      <disk id="8d4bd566-6c86-4592-a4a7-912dbf93c298">
        <storage_domains>
          <storage_domain id="9cb6cb0a-cf1d-41c2-92ca-5a6d665649c9"/>
        </storage_domains>
      </disk>
    <disk_attachment>
  </disk_attachments>
</vm>

When the virtual machine is created from a snapshot this set of disks is slightly different, it uses the image_id attribute instead of id.

<vm>
  ...
  <disk_attachments>
    <disk_attachment>
      <disk>
        <image_id>8d4bd566-6c86-4592-a4a7-912dbf93c298</image_id>
        <storage_domains>
          <storage_domain id="9cb6cb0a-cf1d-41c2-92ca-5a6d665649c9"/>
        </storage_domains>
      </disk>
    <disk_attachment>
  </disk_attachments>
</vm>

It is possible to specify additional virtual machine parameters in the XML description, e.g. a virtual machine of desktop type, with 2 GiB of RAM and additional description can be added sending a request body like the following:

<vm>
  <name>myvm</name>
  <description>My Desktop Virtual Machine</description>
  <type>desktop</type>
  <memory>2147483648</memory>
  ...
</vm>

A bootable CDROM device can be set like this:

<vm>
  ...
  <os>
    <boot dev="cdrom"/>
  </os>
</vm>

In order to boot from CDROM, you first need to insert a disk, as described in the CDROM service. Then booting from that CDROM can be specified using the os.boot.devices attribute:

<vm>
  ...
  <os>
    <boot>
      <devices>
        <device>cdrom</device>
      </devices>
    </boot>
  </os>
</vm>

In all cases the name or identifier of the cluster where the virtual machine will be created is mandatory.

Parameters:

vm (Vm) —

The vm to add.
opts (Hash) (defaults to: {}) —

Additional options.

Options Hash (opts):

:clone (Boolean) —
Specifies if the virtual machine should be independent of the template.

When a virtual machine is created from a template by default the disks of the virtual machine depend on the disks of the template, they are using the copy on write mechanism so that only the differences from the template take up real storage space. If this parameter is specified and the value is true then the disks of the created virtual machine will be cloned, and independent of the template. For example, to create an independent virtual machine, send a request like this:
```
POST /ovirt-engine/vms?clone=true
```
With a request body like this:
```
<vm>
  <name>myvm<name>
  <template>
    <name>mytemplate<name>
  </template>
  <cluster>
    <name>mycluster<name>
  </cluster>
</vm>
```
Note
When this parameter is true the permissions of the template will also be copied, as when using clone_permissions=true.
:clone_permissions (Boolean) —
Specifies if the permissions of the template should be copied to the virtual machine.

If this optional parameter is provided, and its values is true then the permissions of the template (only the direct ones, not the inherited ones) will be copied to the created virtual machine. For example, to create a virtual machine from the mytemplate template copying its permissions, send a request like this:
```
POST /ovirt-engine/api/vms?clone_permissions=true
```
With a request body like this:
```
<vm>
  <name>myvm<name>
  <template>
    <name>mytemplate<name>
  </template>
  <cluster>
    <name>mycluster<name>
  </cluster>
</vm>
```

:filter (Boolean) —

Relevant for admin users only. Indicates whether to assign UserVmManager role on the created Virtual Machine for this user. This will enable the user to later access the Virtual Machine as though he were a non-admin user, foregoing his admin permissions (by providing filter=true).

Note	admin-as-user (meaning providing filter=true) POST requests on an existing Virtual Machine will fail unless the Virtual Machine has been previously created by the admin as a user (meaning with filter=true).

:seal (Boolean) —
Specifies if the virtual machine should be sealed after creation.

If this optional parameter is provided, and its value is true, the virtual machine will be sealed after creation. If the value is 'false', the virtual machine will not be sealed. If the parameter is not provided, the virtual machine will be sealed, only if it is created from a sealed template and its guest OS is not set to Windows.

For example, to create a virtual machine from the mytemplate template and to seal it, send a request like this:
```
POST /ovirt-engine/api/vms?seal=true
```
With a request body like this:
```
<vm>
  <name>myvm<name>
  <template>
    <name>mytemplate<name>
  </template>
  <cluster>
    <name>mycluster<name>
  </cluster>
</vm>
```
:headers (Hash) — default: {} —

Additional HTTP headers.
:query (Hash) — default: {} —

Additional URL query parameters.
:timeout (Integer) — default: nil —

The timeout for this request, in seconds. If no value is explicitly given then the timeout set globally for the connection will be used.
:wait (Boolean) — default: true —

If true wait for the response.

Returns:

(Vm)
