qemu-system-i386: Could not install MSR_CORE_THREAD_COUNT handler: Success

[Vitaly Chikunov]

Hi,

QEMU 7.2.0 when run on 32-bit x86 architecture fails with:

  i586$ qemu-system-i386 -enable-kvm
  qemu-system-i386: Could not install MSR_CORE_THREAD_COUNT handler: Success
  i586$ qemu-system-x86_64 -enable-kvm
  qemu-system-x86_64: Could not install MSR_CORE_THREAD_COUNT handler: Success

Minimal reproducer is `qemu-system-i386 -enable-kvm'. And this only
happens on x86 (linux32 personality and binaries on x86_64 host):

  i586$ file /usr/bin/qemu-system-i386
