--- Comment #8 from Yann Droneaud <yann@droneaud.fr> ---
Bypassing libvirtd, but reusing some of the command line parameter it uses,=
 I
can reproduce the issue with qemu:

  qemu-system-x86_64 -m 1024 \
    -machine pc-q35-5.2,accel=3Dkvm,usb=3Doff,vmport=3Doff,dump-guest-core=
=3Doff \
    -cpu
EPYC-Milan,x2apic=3Don,tsc-deadline=3Don,hypervisor=3Don,tsc-adjust=3Don,va=
es=3Don,vpclmulqdq=3Don,spec-ctrl=3Don,stibp=3Don,arch-capabilities=3Don,ss=
bd=3Don,cmp-legacy=3Don,virt-ssbd=3Don,rdctl-no=3Don,skip-l1dfl-vmentry=3Do=
n,mds-no=3Don,pschange-mc-no=3Don,pcid=3Doff,svme-addr-chk=3Doff
\
    -cdrom  FreeBSD-13.0-RELEASE-amd64-disc1.iso=20

I will try to trim the options to the one that trigger the panic.
