这个问题我以前也碰到了，注意看一下两台主机的BIOS版本，IBM 3650M3主机1.10版本以后启动了AES功能，老的版本中是关闭的。

这个选项会导致你的BVmotion失败。

The default value of the Advanced Encryption Standard (AES) feature is "Enabled" in Unified Extensible Firmware Interface (UEFI) version 1.10 and newer. The default value was disabled in previous versions. The setting must be consistent across two (2) blades to VMotion between them.

The value may need to be set to "Disabled" when using VMotion depending on the processors you are using. See VMware for further detail on whether or not AES should be enabled or disabled for your environment:

该问题会导致以下现象：

Issue 1:

When attempting to use VMotion between two (2) identical servers, the VMotion fails and VMware reports the following error:

Host CPU is incompatible with virtual machine's requirement at CPUID level 0x1

Issue 2:

When using a VMware cluster with EVC enabled in a VCenter server, it is not possible to add a server with Westmere processors to a cluster with the "Intel Xeon 32nm Core i7 ("Westmere")" EVC

option selected.

解决方法：

o disable AES:

1.        Download the Advanced Settings Utility (ASU) utility, version 3.62 from the following URL:

http://www.ibm.com/support/entry ... ay?lndocid=TOOL-ASU

2.        Run the following ASU command:

asu set UEFI.AesEnable Disable

3.        Reboot the server.There is also a bootable tool available to disable this setting on IBM systems:

To enable AES:Install UEFI version 1.10 or newer and restore the default settings in UEFI.
