Commit 027ac0cb516 ("target/i386/hvf: add rdmsr 35H MSR_CORE_THREAD_COUNT") added support for the MSR_CORE_THREAD_COUNT MSR to HVF. This MSR is mandatory to execute macOS when run with -cpu host,+hypervisor. This patch set adds support for the very same MSR to TCG as well as KVM - as long as host KVM is recent enough to support MSR trapping. With this support added, I can successfully execute macOS guests in KVM with an APFS enabled OVMF build, a valid applesmc plus OSK and -cpu Skylake-Client,+invtsc,+hypervisor Alex Alexander Graf (3): x86: Implement MSR_CORE_THREAD_COUNT MSR i386: kvm: Add support for MSR filtering KVM: x86: Implement MSR_CORE_THREAD_COUNT MSR target/i386/kvm/kvm.c | 145 +++++++++++++++++++++++++++ target/i386/kvm/kvm_i386.h | 11 ++ target/i386/tcg/sysemu/misc_helper.c | 5 + 3 files changed, 161 insertions(+)
