Hygon SE
Overview
Hygon SE (Security Element) is an innate security IP core of Hygon processors. It can provide secure, compliant, and standardized encryption capabilities for your applications.
SE devices can be virtualized and attached to VM instances, thus providing secure encryption for VM instances. You can virtualize up to 64 SE devices on the Cloud but we do not recommend that you virtualize more than 24 SE devices in case of reducing the host performance.
Operations
GenerateHygonMdevDevices
Generates Hygon MDEV devices. For example,
GenerateHygonMdevDevices hostUuid=8426a1ab49763402b20d3dbe7061ed6b maxQemuNum=64Parameters
| Name | Description | Optional | Valid Value | Starting Version |
|---|---|---|---|---|
| hostUuid | The host UUID. | 5.5.0 | ||
| systemTags | The system tags. For more information, see CreateSystemTag. | Yes | 5.5.0 | |
| userTags | The user tags. For more information, see CreateUserTag. | Yes | 5.5.0 | |
| maxQemuNum | Specifies how many virtual devices (mdev) each physical CCP card should create for QEMU VM instances. max_qemu_num=128 means each CCP generates 128 mdev devices for VM instances. | 5.5.0 |
UngenerateHygonMdevDevices
Ungenerates Hygon MDEV Devices. For example,
UngenerateHygonMdevDevices hostUuid=3c36d4ec8c3532f2ab7fc63af19f8ad8Parameters
