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:
