Different AMD instance types may require specific versions of drivers and kernels. When you purchase AMD instance types, we recommend that you use operating system versions that are officially supported. This ensures that the operating system images contain the drivers and kernel versions required by your AMD instances. This topic describes the versions of operating system images that are compatible with different generations of AMD instance types.
Background information
AMD instance types are new offerings released by Alibaba Cloud. AMD instance types are powered by AMD EPYCTM x86 microprocessors. The following AMD instance families are available:
Eighth-generation AMD instance family powered by AMD Genoa processors | Seventh-generation AMD instance family powered by AMD Milan processors | Sixth-generation AMD instance family powered by AMD Rome processors |
|

For more information, see Overview of instance families.
Compatibility
Different generations of AMD instance types are compatible with different operating system versions. The AMD Zen architecture was released in 2017. Some new features of processors on the AMD Zen architecture are not supported by earlier versions of operating systems. The following tables describe the operating system versions that support the AMD processors used by different generations of AMD instance types, and provide the official documentation about compatibility for your reference.
When you purchase AMD instance types, we recommend that you use the operating system versions that are described in the following tables. If you want to use operating system versions that are not described in the following tables, take note of the following items:
Select an instance type that supports the operating system version that you want to use.
Use a community image that contains the operating system version that you want to use. For more information, see Create an ECS instance by using a community image.
If you use operating system versions that are not officially supported with AMD instance types, proceed at your own risk.
Operating system versions that support AMD Genoa processors used by eighth-generation AMD instance types
The following table describes the operating system versions that support AMD Genoa processors.
Operating system | Official compatible operating system version | Official documentation about compatibility | Known incompatibility risk |
Windows |
| Windows Server support and installation instructions for the AMD EPYC 9004 Series server processors | None |
Linux |
|
| None |
Operating system versions that support AMD Milan processors used by seventh-generation AMD instance types
The following table describes the operating system versions that support AMD Milan processors.
Operating system | Official compatible operating system version | Official documentation about compatibility | Known incompatibility risk |
Windows |
| Install Windows Server on a computer that uses AMD EPYC 7002 and 7003 Series processors | None |
Linux |
|
| When you start Ubuntu 16 or Debian 9 on a seventh-generation AMD instance, such as g7a instance, system panic occurs. To resolve this issue, install the required patch. For more information, see Re: [PATCH v6 00/12] SVM cleanup and INVPCID feature support. After you install the patch and start Ubuntu 16 or Debian 9 on the instance, the instance may be unstable. |
Operating system versions that support AMD Rome processors used by sixth-generation AMD instance types
The following table describes the operating system versions that support AMD Rome processors.
Operating system | Official compatible operating system version | Official documentation about compatibility | Known incompatibility risk |
Windows |
| Windows Server support and installation instructions for the AMD EPYC 7000 Series server processors | None |
Linux |
|
| None |
