Troubleshooting

Add additional metadata to the uploaded image through the GUI. This step is recommended to ensure proper compatibility with VMware or Hyper-V environments.

- hw_vif_model="e1000"
- hw_disk_bus="sata"

Updating image metadata

1. Navigate to Administrator > Compute > Images.

   

2. Choose desired project, than hover to More, click Manage Metadata to proceed.

   

Setting network driver

• hw_vif_model = e1000

Setting disk bus

• hw_disk_bus="sata"

Glance metadata for UEFI images

- hw_disk_bus='sata'
- hw_firmware_type='uefi'
- hw_machine_type='q35'
- hw_qemu_guest_agent='True'
- os_secure_boot='optional'
- hw_vif_model='e1000'
- hw_video_model='vga'
