Problem
Whenever I boot with "-accel hvf -cpu host", the Ubuntu desktop installer will immediately crash with a kernel panic after the initial splash screen.
See the attached picture of the kernel panic for more details.
Steps to recreate
>From https://www.jwillikers.com/posts/virtualize_ubuntu_desktop_on_macos_with_qemu/
1. Install QEMU with Homebrew.
$ brew install qemu
2. Create a qcow2 disk image to which to install.
$ qemu-img create -f qcow2 ubuntu2004.qcow2 60G
3. Download the ISO.
$ curl -L -o ubuntu-20.04.1-desktop-amd64.iso https://releases.ubuntu.com/20.04/ubuntu-20.04.1-desktop-amd64.iso
4. Run the installer in QEMU.
$ qemu-system-x86_64 \
-accel hvf \
-cpu host \
-smp 2 \
-m 4G \
-usb \
-device usb-tablet \

Workaround
Emulating the CPU with "-cpu qemu64" does not result in a kernel panic.

0f 01 f9 is RDTSCP; use -cpu host,-rdtscp to mask out the feature. KVM
couldn't pass the feature through for a while, and HVF currently can't,
though HVF should be modified to automatically hide the feature until it
can emulate it.
