Supported guest operating systems
For information about installing supported guest operating systems in VMware VMs, refer to the
VMware
Guest Operating System Installation Guide
.
If VMware VMs are being configured with IPv6 for VxBlock Sytems, a
vmxnet
driver must be deployed.
This should occur automatically when VMware Tools are installed.
IPv6 is not supported on vSphere 6.5.

Using VMware Enhanced vMotion Compatibility with Cisco
UCS blade servers
Ensure Enhanced vMotion Compatibility (EVC) when upgrading Cisco UCS blade servers in a .
Do not mix Cisco UCS blade server types within a cluster. However, there are instances when it is
necessary to mix blade types, including upgrades.
When upgrading Cisco UCS blade servers, consider the following guidelines:
•
Cisco UCS Blade Servers B200 M1 through B200 M3 support EVC mode Intel Nehalem
Generation (Xeon Core i7). Individual Cisco UCS blade servers support several EVC modes, but
only Xeon Core i7 is a commonly supported mode across all three Cisco UCS blade servers. If
the CPU feature sets are greater than the EVC mode you are enabling, power down all VMs in
the cluster and enable or modify the EVC mode.
•
Cisco UCS Blade Servers B200 M1 and M2 support some additional CPU features such as those
provided in 32-nanometer EVC mod), but some might not be enabled in the BIOS due to U.S.
export rules. To ensure complete and reliable vMotion compatibility when mixing blade types in a
single cluster, use Intel Xeon Core i7 EVC mode.
•
If all the Cisco UCS blade servers in the cluster have the same CPU type, set the EVC mode to
CPU architecture. For example, if the cluster contains all Cisco UCS Blade Servers B200 M1,
select Intel Xeon Core i7 EVC mode. This allows vMotion compatibility between Cisco UCS Blade
Servers B200 M1 and other hosts. EVC mode should only be enabled if you are adding or
planning to add hosts with newer CPUs to an existing cluster.
•
Set the EVC mode before you add Cisco UCS blade servers with newer CPUs to the cluster. This
eliminates the need to power down the VMs running on the blade servers. Setting a lower EVC
mode than the CPU can support may hide some CPU features, which may impact performance.
Proper planning is needed if performance or future compatibility within the cluster is desired.
