Creating virtual machines with UEFI boot

You can create virtual machines with UEFI boot from either templates (QCOW2 images) or ISO images.

Prerequisites

• You have an image uploaded to the compute cluster, as described in Preparing boot media for virtual machines.
• To create a VM with UEFI boot from a template, ensure that your QCOW2 image has UEFI boot already enabled.
• To authorize further OpenStack commands, the OpenStack command-line client must be configured, as outlined in Connecting to OpenStack command-line interface.

To create a virtual machine with UEFI boot from a template

1. Find out the ID of the required template with UEFI. For example:

   # openstack --insecure image list | grep centos.qcow2
   | 007db63f-9b41-4918-b572-2c5eef4c8f4b | centos7.qcow2 | active |
   

2. Specify the UEFI firmware for this template by using the hw_firmware_type property. For example:

   # openstack --insecure image set --property hw_firmware_type=uefi 007db63f-9b41-4918-b572-2c5eef4c8f4b

3. Create a VM from this template in the command-line or user interface.

To create a virtual machine with UEFI boot from an ISO image

1. Find out the ID of the required ISO image. For example:

   # openstack --insecure image list | grep centos.iso
   | c9d6f6e9-9c6d-4d1c-824f-c3542f70fdb0 | centos7.iso | active |
   

2. Specify the UEFI firmware for this ISO image by using the hw_firmware_type property. For example:

   # openstack --insecure image set --property hw_firmware_type=uefi c9d6f6e9-9c6d-4d1c-824f-c3542f70fdb0

3. Create a VM from this ISO image in the command-line or user interface.

4. When the VM is launched, shut it down, and then specify the UEFI firmware for this VM's boot volume by using the hw_firmware_type property. For example, if the boot volume ID is 12d360f4-afe8-48c9-af24-7f048dcec0c9, run:

   # openstack --insecure volume set --image-property hw_firmware_type=uefi 12d360f4-afe8-48c9-af24-7f048dcec0c9

5. Start the VM and continue the guest OS installation.
