4.11. 创建虚拟机磁盘

以下示例为示例虚拟机创建一个 8 GiB 写时复制磁盘。

请求应类似如下：

POST /ovirt-engine/api/vms/007/diskattachments HTTP/1.1
Content-Type: application/xml
Accept: application/xml

请求正文应该是类型为 DiskAttachment 的对象，描述磁盘以及如何将其附加到虚拟机：

<disk_attachment>
  <bootable>false</bootable>
  <interface>virtio</interface>
  <active>true</active>
  <disk>
    <description>My disk</description>
    <format>cow</format>
    <name>mydisk</name>
    <provisioned_size>8589934592</provisioned_size>
    <storage_domains>
      <storage_domain>
        <name>mydata</name>
      </storage_domain>
    </storage_domains>
  </disk>
</disk_attachment>

同一个请求，使用 curl 命令：

# curl \
--cacert '/etc/pki/ovirt-engine/ca.pem' \
--user 'admin@internal:mypassword' \
--request POST \
--header 'Version: 4' \
--header 'Content-Type: application/xml' \
--header 'Accept: application/xml' \
--data '
<disk_attachment>
  <bootable>false</bootable>
  <interface>virtio</interface>
  <active>true</active>
  <disk>
    <description>My disk</description>
    <format>cow</format>
    <name>mydisk</name>
    <provisioned_size>8589934592</provisioned_size>
    <storage_domains>
      <storage_domain>
        <name>mydata</name>
      </storage_domain>
    </storage_domains>
  </disk>
</disk_attachment>

storage_domains 属性告知 API 将磁盘存储在 mydata 存储域中。
