HP Integrity Virtual Machines 4.3: Installation, Configuration, Administration

NOTE: The Cisco switch for HP BladeSystem c-Class Server Blades has a protocol error that
causes it to respond to every MAC address. Because MAC addresses are unique, Integrity VM
checks that the generated guest virtual MAC address is unique. If one of these bad switches is
on your network, Integrity VM's check will fail.
The hpvmcreate command might fail with messages like the following:
hpvmcreate: WARNING (host): Failed after 3 attempts.
hpvmcreate: WARNING (host): Unable to create Ethernet MAC Address.
Similarly, the hpvmstart command might fail with messages like the following:
# hpvmstart -P vm2
HPVM guest vm2 configuration problems:
Warning 1 on itme nic1: Guest MAC address for switch nic1 is in use.
Cisco Systems, Inc. released a fix for the Cisco Catalyst Blade Switch 3020 in December 2006,
which is available from the Cisco Systems website:
http://cco.cisco.com
It is also available from the HP website:

From the HP website, select Software & Driver downloads and search for switch cisco 3020. The
minimum required firmware version is 12.2(35) SE.
7.2.1.1 Local Networks
Virtual network communication may be limited to virtual machines on the VM Host system
through the use of vswitches that are not connected to a physical NIC. A virtual network such
as this is called a local virtual network or simply a local network (localnet). To create a local
network, a vswitch must first be created using hpvmnet without the -n option, so that it is not
connected to the physical network. For example, to create a local network vswitch named clan0,
enter the following commands:
# hpvmnet -c -S clan0
# hpvmnet -b -S clan0
All vNICs connected to that vswitch will then be on the same local network. The VM Host does
not communicate on local networks.
The following command adds a vNIC to the guest host1, which can be used to communicate
with any virtual machine connected to the localnet vswitch.
# hpvmmodify -P host1 -a network:lan::vswitch:clan0
During startup of the Integrity VM software, a default vswitch, localnet, is created and booted.
The localnet vswitch can be added to a guest, which allowsOk communication between any other
guest using the localnet vswitch. For example:
# hpvmmodify -P compass1 -a network:lan::vswitch:localnet
7.2.2 Changing vswitches
You can use the -C option to change the physical network interface card (pNIC) the guest has
in use. For example, enter the lanscan command, as follows:
# lanscan
