Description of problem: qemu core dump with '-cpu host,mpx=off' on Cascadelake host Version-Release number of selected component (if applicable): Host: kernel-4.18.0-502.el8.x86_64 qemu-kvm-6.2.0-35.module+el8.9.0+19166+e262ca96.x86_64 Model name: Intel(R) Xeon(R) Silver 4210 CPU @ 2.20GHz How reproducible: 6/6 Steps to Reproduce: 1. Boot qemu with '-cpu host,mpx=off' # /usr/libexec/qemu-kvm -cpu host,mpx=off 2. 3. Actual results: # /usr/libexec/qemu-kvm -cpu host,mpx=off qemu-kvm: error: failed to set MSR 0x48f to 0xffefff00036dfb qemu-kvm: ../target/i386/kvm/kvm.c:2953: kvm_buf_set_msrs: Assertion `ret == cpu->kvm_msr_buf->nmsrs' failed. Aborted (core dumped) Expected results: qemu can boot up without error. Additional info: Didn't reproduce this issue with qemu8.0 with rhel9 kernel on Cascadelake.
