Re: [libvirt] [PATCH 0/7] qemu: Report better host-model CPUs in domain caps

One of the main reasons for introducing host-model CPU definition in a domain capabilities XML was the inability to express disabled features in a host capabilities XML. That is, when a host CPU is, e.g., Haswell without x2apic support, host capabilities XML will have to report it as Westmere + a bunch of additional features., but we really want to use Haswell - x2apic when creating a host-model CPU. Unfortunately, I somehow forgot to do the last step and the code would just copy the CPU definition found in the host capabilities XML. This changed recently for new QEMU versions which allow us to query host CPU, but any slightly older QEMU will not benefit from any change I did. This patch makes sure the right CPU model is filled in the domain capabilities even with old QEMU. The issue was reported in https://bugzilla.redhat.com/show_bug.cgi?id=1426456 Jiri Denemark (7): Do not format <arch> in guest CPU XML cpu: Replace cpuNodeData with virCPUGetHost cpu: Add virCPUType parameter to virCPUGetHost cpu: Add list of allowed CPU models to virCPUGetHost qemu: Refactor virQEMUCapsInitCPU qemu: Report better host-model CPUs in domain caps cputest: New test for Intel Core i7-4510U
