Emulation type for the boot volume.
Before you change the boot volume attachment type, detach all block volumes and VNICs except for the boot volume and the primary VNIC.
If the instance is running when you change the boot volume attachment type, it will be rebooted.
Whether to enable in-transit encryption for the volume's paravirtualized attachment. To enable in-transit encryption for block volumes and boot volumes, this field must be set to {@code true}.
Data in transit is transferred over an internal and highly secure network. If you have specific compliance requirements related to the encryption of the data while it is moving between the instance and the boot volume or the block volume, you can enable in-transit encryption. In-transit encryption is not enabled by default.
All boot volumes and block volumes are encrypted at rest.

Emulation type for the physical network interface card (NIC).
Before you change the networking type, detach all VNICs and block volumes except for the primary VNIC and the boot volume.
The image must have paravirtualized drivers installed. For more information, see [Editing an Instance](https://docs.cloud.oracle.com/iaas/Content/Compute/Tasks/resizinginstances.htm).
If the instance is running when you change the network type, it will be rebooted.
