Network Adapters and Legacy Virtual Machines
Legacy virtual machines are virtual machines that are supported by the product in use, but are not current
for that product. The default network adapter types for all legacy virtual machines depend on the adapters
available and compatible to the guest operating system and the version of virtual hardware on which the
virtual machine was created.
If you do not upgrade a virtual machine to correspond with an upgrade to a newer version of an ESXi
host, your adapter settings remain unchanged. If you upgrade your virtual machine to take advantage of
newer virtual hardware, your default adapter settings will likely change to be compatible with the guest
operating system and upgraded host hardware.
To verify the network adapters that are available to your supported guest operating system for a particular
version of vSphere ESXi, see the VMware Compatibility Guide at
http://www.vmware.com/resources/compatibility.
Change the Virtual Machine Network Adapter Configuration
You can change the virtual machine network configuration, including its power-on behavior and resource
allocation.
For details about configuring the networking for virtual machine network adapters, see the vSphere
Networking documentation.
Prerequisites
Required privilege: Network.Assign network on a network if you are changing the network the virtual
machine connects to.
Procedure
1 Right-click a virtual machine in the inventory and select Edit Settings.
2 On the Virtual Hardware tab, expand Network adapter, and select the port group to connect to from
the drop-down menu.
The menu lists all standard and distributed port groups that are available for virtual machine use on
the host.
If you want to provision bandwidth to the network adapter from a reserved quota by using vSphere
Network I/O Control version 3, select a port group that is associated with the network resource pool
that provides the quota.
