HP Integrity Virtual Machines 4.3: Installation, Configuration, Administration

network:adaptertype:bus,device,mac-addr:vswitch:vswitch-name:portid:portnumber
If you omit any portion of the network resource specification, use the colon character (:) as a field
delimiter.
The guest virtual network information consists of the following fields, separated by colons:
• network
• adaptertype (virtual device adapter type): lan , avio_lan
• :bus,device,mac-addr (virtual network device hardware address) (optional)
The virtual network device hardware address consists of three fields, separated by commas:
— bus (the virtual network device PCI bus number)
— device (the 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 verify that it is unique, because the
address cannot conflict with any of the VM Host's physical network adapter MAC
addresses, and to verify that the proper bits are set. You can specify either the bus and
device with the MAC address or the MAC address without the bus and device, or you
can omit the entire hardware address. If you do not specify the virtual network device
hardware address, or a portion of it, the missing information is generated automatically.
If you specify only a portion of the virtual network device hardware address (for
example, just the MAC address), include the commas (for example
,,aa-bb-cc-00-11-22).
When you add a virtual NIC to your guest, Integrity VM checks to make sure the MAC
address is unique.
By default, Integrity VM makes three attempts (each with a one-second timeout) to
determine the validity of the MAC address for the virtual NIC. This process can result
in up to ten seconds of delay for each defined virtual NIC. To speed up this processing,
add the following tunable to the /etc/rc.config.d/hpvmconf configuration file:
HPVMMACADDRFRAMES=n
Where n is the number of attempts (1 to 30). The default is 3. A value of 1 or 2 increases
performance at the risk of missing a response from a slow NIC.
You can set the HPVMMACADDRFRAMES tunable to zero (0), which completely eliminates
the MAC address verification. However, HP recommends that you do so after you
configure all of your guests and confirm that there are no conflicts with MAC addresses
in your network environment.
To boost virtual network performance, create additional vswitches and allocate them
across guests.
The virtual switch information consists of the following fields, separated by a colon:
• vswitch
• vswitch-name (the name assigned to the virtual network switch)
• portnumber (the number of the port on the vswitch)
The following example associates a guest virtual network device with a vswitch:
network:avio_lan:0,1,02-02-03-04-05-06:vswitch:net1
• The guest virtual network device type is network.
• The virtual adapter type is avio_lan.
• The virtual PCI bus number is 0.
• The virtual PCI slot number is 1.
• The virtual MAC address is 02-02-03-04-05-06.
