How do I enable enhanced vMotion?

How do I enable enhanced vMotion?

Procedure

1. Select a cluster in the vSphere inventory.
2. Power off all the virtual machines on the hosts with feature sets greater than the EVC mode.
3. Click the Configure tab, select VMware EVC, and click Edit.
4. Enable EVC for the CPU vendor and feature set appropriate for the hosts in the cluster, and click OK.

What is enhanced vMotion in VMware?

VMware Pages You can use the Enhanced vMotion Compatibility (EVC) feature to help ensure vMotion compatibility for the hosts in a cluster. EVC ensures that all hosts in a cluster present the same CPU feature set to virtual machines, even if the actual CPUs on the hosts differ.

How can I improve my vSphere vMotion performance?

Add more physical NICs or NICs with multiple 1Gb ports You can add multiple physical NICs to your host and use the aggregated bandwidth to speed up the vMotion process. There are single, double, or even quad-port NIC models on the market that will fit this scenario.

How do I enable enhanced vMotion compatibility EVC processor support?

To resolve this issue enable Enhanced vMotion Compatibility (EVC) on the cluster: EVC solves this by creating a baseline set to the least advanced processor configuration supported by all ESXi hosts in the cluster.

How do I know if my EVC is enabled?

Procedure

1. Navigate to a cluster or a host in the vCenter Server inventory.
2. Click the VMs tab.
3. To verify the status of the CPU mode, check the EVC CPU Mode column.
4. To verify the status of the graphics mode, check the EVC Graphics Mode (vSGA) column.

How do I enable EVC per VM?

Enabling Per-VM EVC

1. In the vSphere Client, navigate to the virtual machine.
2. Under the Configure tab, select VMware EVC.
3. Click Edit and select whether to enable or disable EVC.
4. If you want to enable EVC, choose a baseline CPU feature set from the VMware EVC Mode drop-down menu and click OK.

Why is EVC needed?

One can e-verify his/her income tax return by using the Electronic Verification Code (EVC) sent to one’s email id or via Net banking. A taxpayer is required to verify the online income tax return filed by him by submitting a signed hard copy of the same to the Income Tax Central Processing Unit.

What is EVC vMotion?

VMware EVC is a feature in VMware vSphere virtualization that allows virtual machines (VMs) to move between ESX/ESXi hosts on different CPUs. VMware EVC stands for VMware Enhanced vMotion Compatibility.

Should vMotion use jumbo frames?

Use of Jumbo Frames is recommended for best vMotion performance. To determine the maximum number of concurrent vMotions possible, see the Concurrent migration limits at Limits on Simultaneous Migrations in the vSphere Web Client.

Does vMotion require jumbo frames?

Use jumbo frames for best vMotion performance. Ensure that jumbo frames are enabled on all network devices that are on the vMotion path including physical NICs, physical switches, and virtual switches.

How do I know if my EVC is compatible?

To determine the EVC modes compatible with your CPU, search the VMware Compatibility Guide. Search for the server model or CPU family, and click the entry in the CPU Series column to display the compatible EVC modes.

Can you enable EVC without downtime?

In some cases, you can enable the EVC mode in the entire cluster without any VM downtime (generally, VMs must be shut down and powered on to apply the cluster EVC mode settings). This is possible if the following requirements are met: Running VMs reside on the ESXi host with the oldest processor.

Does enabling EVC require a reboot?

New EVC mode features are not available to the virtual machines until they are powered off and powered back on again. A full power cycling is required. Rebooting the guest operating system or suspending and resuming the virtual machine is not sufficient.

How long is EVC valid?

What is the validity of the generated EVC? The EVC generated will be valid for 72 hours from the time of generation.

Should you enable EVC mode?

The general recommendation is to have EVC enabled as it will help you in the future where you’ll be scaling your clusters with new hosts that might contain new CPU models. To enable EVC in a brownfield scenario can be challenging. That’s why we stress to have it enabled from the get-go.

Does EVC mode affect performance?

Generally the consensus is that setting the EVC mode on a cluster is a good thing to make it easier to admit future ESXi hosts and it doesn’t cause any performance degradation. After all, even with it set, it doesn’t prevent you from using the latest clock frequencies, deeper core counts, etc.

What is MTU vMotion?

For high availability of vMotion, it is important for the large ping test check to succeed. The MTU check uses large packets of up to 9000 Bytes.

Does vMotion need a gateway?

The only thing that you really need is the default gateway for the vMotion TCP/IP stack. This can be found by browsing to the Host > Manage > Network > TCP/IP configuration and editing the vMotion TCP/IP stack. For this host, the gateway is 172.17.
