[libvirt] [PATCH v2 0/7] Finish support for IA32_ARCH_CAPABILITIES MSR features
As promised in v1 this series contains a few additional patches which
limit usage of MSR features to QEMU that supports "unavailable-features"
CPU property.
This series intentionally enables MSR features for all QEMU versions
before restricting the usage to make this restriction more visible in
the test results.
Version 2:
- all but 2 patches from version 1 were pushed
- 5 new patches
Jiri Denemark (7):
conf: Introduce virCPUDefCheckFeatures
cpu_x86: Turn virCPUx86DataIteratorInit into a function
cpu_x86: Introduce virCPUx86FeatureIsMSR
cpu_x86: Read CPU features from IA32_ARCH_CAPABILITIES MSR
cpu_map: Introduce IA32_ARCH_CAPABILITIES MSR features
qemu: Forbid MSR features with old QEMU
qemu: Drop MSR features from host-model with old QEMU
