This patch set in combination with its kernel kvm patch set proposes an
implementation of S390 cpu models. The origin of this item is to provide
a means for management interfaces like libvirt to draw decisions if life
guest migration to a target hypervisor is reasonable.
A migration constraint is that a target hypervisor is capable to run a
guest with the same S390 cpu model as the source hypervisor does. To
verify this condition, the administration interface employes the existing
QMP command "query-cpu-definitions" which returns a list of all currently
supported S390 cpu models of a given host system. Together with the newly
defined QMP command "query-cpu-model", which returns the current active
S390 cpu model of a guest, a conclusion can be drawn if a migration is
possible.
A S390 cpu model is defined as a triple of machine type, cpu facility set
and IBC value. Each historic, current and future triple receives a name
composed of the machine type and its general availability counter. This name
forms the cpu model name (e.g.: "2817-GA2".)
With means of the Instruction Blocking Control feature (IBC), the instruction
set available to a given guest is limitable.
