FreeBSD 13.1 Installer hang at virtio-random

Vultr QEMU Q35 hangs while booting during virtio-random initialization on
FreeBSD-13.1-RELEASE and FreeBSD-14.0-CURRENT.

Vultr engineering has temporarily worked around it by blacklisting
virtio-random on their FreeBSD images  and/or falling back to i440fx
virtualization.  This requires that users installing FreeBSD from their own
known media have to do one of the following:

* modify their ISO to blacklist virtio-random=20
* do the kludge of installing a Vultr FreeBSD image (which defaults to i440=
fx
emulation) and then reinstalling via an attached ISO image.=20=20
* setting 'hint.vtrnd.0.disabled=3D1=E2=80=99 at the loader prompt and boot=
ing.

To quickly spin up a VM I use a raw image from the FreeBSD images -- custom=
ized
with pre-loaded configuration -- but it has the exact same hang unless I mo=
dify
it to blacklist virtio-random.=20=20

This bug comment has information from Vultr engineering corroborating the
issue.

bug #254513, comment #c32

I=E2=80=99ve attached images of the FreeBSD-13.1 RELEASE via the VNC consol=
e, first
from the boot installer hang and subsequently from single user with a
subsequent kldload virtio-random which causes an immediate hang.  Apologize=
 for
the images but the Vultr console doesn=E2=80=99t allow cut and paste of the=
 screen.

Please let me know if I can provide any other information.
