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
