Dear Maintainer,
VMs controlled by libvirt failed to start when using "host" cpu type with kvm
acceleration
libvirt log gives:

qemu-system-x86_64: ../../target/i386/kvm/kvm.c:2996: kvm_buf_set_msrs:
Assertion `ret == cpu->kvm_msr_buf->nmsrs' failed.
Please show the complete qemu command line (it should be available in the log
too).
This assertion does not look like something cpu-feature-specific, it smells
like a bug by its own, not depending on -cpu host.
Thanks,
