Sorry, no input from me. OVMF is apparently from November 2018, and QEMU
is version 3.1. Please try to reproduce with recent upstream components
(build both OVMF and QEMU from source), and if the issue persists,
please provide the complete QEMU command line, capture the OVMF debug
log (see OvmfPkg/README for instructions on that), and please also
provide the host CPU characteristics (/proc/cpuinfo,
/sys/module/kvm_*/parameters/*).

I did try the most recent OVMF from QEMU 5.0
(https://git.qemu.org/?p=qemu.git;a=blob_plain;f=pc-
bios/edk2-x86_64-code.fd.bz2;hb=fdd76fecdde) and there was no
difference.
I will re-build qemu sometime soon.
