8.7.2 Changing CPUIDs for Guests
To be able to migrate a VM Guest from one VM Host Server to a different VM Host
Server, it is mandatory, that the VM Guest system only uses CPU features that are
available on both VM Host Server systems. If the actual CPUs are different on both
hosts, it may be necessary to hide some of the features before the VM Guest is started
in order to maintain the possibility to migrate the VM Guest between both hosts. For
fully virtualized guests, this can be achieved by configuring the cpuid that is available
to the guest.
To gain an overview of the current CPU, have a look at /proc/cpuinfo. This con-
tains all the important information that defines the current CPU.
To redefine a CPU, first have a look at the respective cpuid definitions of the CPU
vendor. These are available from:
