Managing vNICs

After you create the vswitch, you can allocate it to one or more virtual machines for use by guest operating systems and applications. To create a vNIC for a virtual machine, enter one of the following commands:

To create a new virtual machine with one vswitch:
# hpvmcreate -P vm-name -a network:adapter-type:[hardware-address]:vswitch:vswitch-name
To create a new virtual machine based on the configuration of an existing virtual machine:
# hpvmclone –P vm-name —a network:adapter-type:[hardware-address]:vswitch:vswitch-name
The vNIC specified with this command is added to the new virtual machine.
To modify an existing virtual machine:
# hpvmmodify –P vm-name —a network:adapter-type:[hardware-address]:vswitch:vswitch-name
The —a option adds the specified vNIC to the virtual machine.




	NOTE: If you modify a vNIC from `lan` to `avio_lan`, or `avio_lan` to `lan`, you must restart the vswitch.

As with virtual storage devices, use the -a rsrc option to associate a guest virtual network device with a vswitch. Before you use this option to associate the virtual network device with a vswitch, create the vswitch using the hpvmnet command. The format of the rsrc parameter for network devices is:

network:adapter-type:[hardware-address]:vswitch:vswitch-name

The guest virtual network device information consists of the following fields, separated by colons:

network
adapter-type, which can be either lan or avio_lan
[hardware-address] (optional), formatted as bus,device,mac-addr. If you do not specify the hardware address, or a portion of it, the information is generated for you. HP recommends allowing Integrity VM to generate the hardware address. The hardware address consists of the following information:
- bus (virtual network device PCI bus number)
- device (virtual network device PCI slot number)
- mac-addr (the virtual network device MAC address) in either of the following formats: 0xaabbcc001122 or aa-bb-cc-00-11-22. The MAC address that you enter is checked to make sure it does not conflict with any of the VM Host’s physical network adapter MAC addresses.
vswitch
The virtual switch information is formatted as vswitch:vswitch-name (where vswitch-name is the name assigned to the virtual network switch when you create it using the hpvmnet command)

Removing vNICs

To remove a vNIC from a virtual machine's configuration, first stop the guest using the hpvmstop command. Then use the -d option to the hpvmmodify command. The -d option allows you to specify the vswitch and the vNIC information. The following is the syntax of the hpvmmodify -d command:

hpvmmodify -P vm-name -d network:adapter-type:[hardware-address]:vswitch:vswitch-name

After making this change, start the guest using the hpvmstart command.
