Remove probing of CPU models when launching QEMU guests When launching a QEMU guest the binary is probed to discover the list of supported CPU names. Remove this probing with a simple lookup of CPU models in the qemuCapsPtr object. This avoids another invocation of the QEMU binary during the startup path. As a nice benefit we can now remove all the nasty hacks from the test suite which were done to avoid having to exec QEMU on the test system. The building of the -cpu command line can just rely on data we pre-populate in qemuCapsPtr. Signed-off-by: Daniel P.

qemu: parse and create -cpu ...,-kvmclock QEMU supports a bunch of CPUID features that are tied to the kvm CPUID nodes rather than the processor's. They are "kvmclock", "kvm_nopiodelay", "kvm_mmu", "kvm_asyncpf". These are not known to libvirt and their CPUID leaf might move if (for example) the Hyper-V extensions are enabled. Hence their handling would anyway require some special-casing. However, among these the most useful is kvmclock; an additional "property" of this feature is that a <timer> element is a better model than a CPUID feature. Although, creating part of the -cpu command-line from something other than the <cpu> XML element introduces some ugliness.
