Some architectures (S390) depend on QEMU to compute baseline CPU model and
expand a models feature set.
Interacting with QEMU requires starting the QEMU process and completing one or
more query-cpu-model-baseline QMP exchanges with QEMU in addition to a
query-cpu-model-expansion QMP exchange to expand all features in the model.
See "s390x CPU models: exposing features" patch set on Qemu-devel for
discussion
of QEMU aspects.
This is part of resolution of: https://bugzilla.redhat.com/show_bug.cgi?id=1511999
-----
This patch set fixes all process code issues identified here:
https://www.redhat.com/archives/libvir-list/2018-November/msg00349.html
in patches 1-22 of the series.
The remaining patches implement the BaselineHypervisorCPU changes using
the non-domain qemu process code.
The process changes (patches 1-22)...
- Make the process code generic (not capabilities specific) for use by
BaselineHypervisorCPU
- Many of the process patches are simple code moves with implementation
changes in other distinct patches
- A thread safe library function creates a unique directory under libDir for each QEMU
process (for QMP messaging) to decouple processes in terms of sockets and
file system footprint.
The BaselineHypervisorCPU changes (patches 22-36)...
- Fix all issues raised in patch sets 1-4.
Thanks,
Chris
