Add VMkernel NIC2023/03/17
 
To add VMkernel NIC, configure like follows.
If you like to set multiple IP address to ESXi Host, it needs to add VMkernel NIC.
Therefore, this is based on that your ESXi computer has multiple physical network interfaces.
This example is based on the environment like follows.
Add VMkernel NIC setting to physical NIC [vmnic1] that has no setting now and assign it to the vswitch and portgroup created in advance.
