Hyper-V Network Adapters Test

There are two types of network adapters available for Hyper-V: a network adapter and a legacy network adapter. For the network adapter to work, integration services must be installed, which is part of the Hyper-V installation. If integration services cannot be installed because of the version of the operating system, the network adapter cannot be used. Instead, you need to add a legacy network adapter that emulates an Intel 21140-based PCI Fast Ethernet Adapter and works without installing a virtual machine driver. A legacy network adapter also supports network-based installations because it includes the ability to boot to the Pre-Execution Environment (PXE boot). The legacy network adapter is also required if a virtual machine needs to boot from a network. You will need to disable the network adapter after the PXE boot.

Hyper-V allows guest computers to share the same physical network adapter. It is therefore necessary for administrators to monitor how each of the physical network adapters are used by both the guest VMs and the host operating system, so that they can accurately determine which adapter is experiencing high usage levels, and also figure out where the network resources are spent more – at the VM-level or at the host operating system-level?

To determine how the Hyper-V operating system utilizes these network adapters, periodically execute the Hyper-V Network Adapters test.

Target of the test : A Hyper-V / Hyper-V VDI server

Agent executing the test : An internal agent

Output of the test : One set of results for each network adapter available to the Hyper-V host monitored

Configurable parameters for the test
  1. Test period - How often should the test be executed
  2. Host - The host for which the test is to be configured.

Indicates whether/not this network adapter is enabled.

 

The values that this measure reports and the numeric values that correspond to them have been discussed in the table below:

State Numeric Value
No 0
Yes 1

Note:

By default, this measure reports the Measure Values listed in the table above to indicate whether/not this network adapter is enabled. The graph of this measure however, represents the same using the numeric equivalents only.

Uplink status:

Indicates the current uplink status of this network adapter.
