Managing Virtual Network Adapters

Virtual network adapters (a.k.a VMKernel networks) handle host network services over a vSphere distributed switch.

You can configure VMkernel virtual adapters for a host through an associated vSphere distributed switch either by creating new virtual adapters or migrating existing virtual adapters.

Create a VMkernel Network Adapter on a vSphere Distributed Switch

let’s create a VMkernel network adapter for use as a vMotion interface or an IP storage port group.

Procedure

1 Log in to the vSphere Client and select the Hosts and Clusters inventory view.
2 Select the host in the inventory pane.
3 On the host Configuration tab, click Networking.
4 Select the vSphere Distributed Switch view.
5 Click Manage Virtual Adapters.

8 Select VMkernel and click Next.

9 Choose a distributed port or distributed port group connection for the virtual adapter.

10 Select Use this virtual adapter for vMotion to enable this port group to advertise itself to another ESXi
host as the network connection where vMotion traffic is sent.

You can enable this property for only one vMotion and IP storage port group for each host. If this property
is not enabled for any port group, migration with vMotion to this host is not possible.

11 Choose whether to Use this virtual adapter for fault tolerance logging. (I’ve selected FT in this case)
12 Choose whether to Use this virtual adapter for management traffic, and click Next.
13 Under IP Settings, specify the IP address and subnet mask.
IPv6 cannot be used with a dependent hardware iSCSI adapter.

14 Click Edit to set the VMkernel default gateway for VMkernel services, such as vMotion, NAS, and iSCSI.

15 On the DNS Configuration tab, the name of the host is entered by default. The DNS server addresses and
domain that were specified during installation are also preselected.

16 On the Routing tab, enter gateway information for the VMkernel. A gateway is needed for connectivity to machines not on the same IP subnet as the VMkernel. Static IP settings is the default. Do not use routing with software iSCSI Multipathing configurations or
dependent hardware iSCSI adapters.

17 Click OK, and then click Next.
18 Click Finish.
