The QEMU project is currently moving its bug tracking to another system.
For this we need to know which bugs are still valid and which could be
closed already. Thus we are setting older bugs to "Incomplete" now.
If you still think this bug report here is valid, then please switch
the state back to "New" within the next 60 days, otherwise this report
will be marked as "Expired". Or please mark it as "Fix Released" if
the problem has been solved with a newer version of QEMU already.
Thank you and sorry for the inconvenience.

Title:
MacOS host qemu-system-x86_64 -cpu host not working
Status in QEMU:
Incomplete
Bug description:
MacOS: 10.15.4
uname -a: Linux door 4.15.0-96-generic #97-Ubuntu SMP Wed Apr 1 03:25:46 UTC
2020 x86_64 x86_64 x86_64 GNU/Linux
I am using qemu on mac host, with ubuntu client.
I used to have "-cpu host" in my qemu command as follow:-
qemu-system-x86_64 \
-no-user-config \
-nodefaults \
-name u64d01 \
-show-cursor \
-M q35,accel=hvf,usb=off,vmport=off \
-cpu host \
-m 8192M \
-smp 4 \
-rtc base=utc,clock=host \
-device virtio-blk-pci,drive=ssd1 \
-drive id=ssd1,file=/Users/js/code/vm/qemu/u64d01.qcow2,if=none,format=qcow2 \
-device virtio-net-pci,netdev=nic1,mac=52:54:98:76:54:33 \
-netdev user,id=nic1,ipv4=on,ipv6=on,hostname=u64d01,hostfwd=tcp::2222-:22 \
-device virtio-tablet-pci \
-device virtio-vga \
-device ich9-intel-hda,id=snd,msi=on \
-device hda-output,id=snd-codec0,bus=snd.0,cad=0,audiodev=snd0 \
-audiodev coreaudio,id=snd0
Base on log of one of the vm, it was definitely working on
2020-01-17(base on journal inside vm), with qemu 4.2.0, which I
installed with brew.
The only way to make it work is to remove "-cpu host".
Already tried with 4.1.1, 4.2 and 5.0rc2. Same result.
To reproduce, try above with a Ubuntu 18.04 installation cd. Client
will crash during kernel loading.
