# Commit 473a49460db0a90bfda046b8f3662b49f94098eb (qemu) makes "no_floppy = 0"
# for pc-q35-2.3 hardware, and OS X doesn't like this (it hangs at "Waiting for
# DSMOS" message). Hence, we switch to pc-q35-2.4 hardware.

# Network device "-device e1000-82545em" can be replaced with "-device vmxnet3"

# this is not using tun/tap interfacing and does not require you to be root
# on macOS, connect to ethernet using DHCP (auto IP assign) method, and you're done!

Hi,

I am trying to boot up High Sierra on Ubuntu 16.04, qemu 2.11.91.

I managed to boot it to clover, but neither keyboard nor mouse are working.

Btw, I am connecting to host via ssh -X

Any suggestions?

HiSierra changed the CPU requirements.
2.14+ TY, Im using 2.19 and QEMU 3 sources.

1- youre supposed to dump the apple smc- not blast the net w apples PROM dumped code.
2- try this.

qemu-system-x86_64 -enable-kvm -m 4096 -cpu Penryn,kvm=on,vendor=GenuineIntel,+invtsc,vmware-cpuid-freq=on,+aes,+xsave,+avx,+xsaveopt,avx2,+smep\

MoJave requires METAL/ 4GB+ UEFI AMD hardware and even more options. AMDFX still beats MoJaves CPU requirements.

clover disk image works just fine. So its a native install. Clone your mac HDD with dd and qcow convert it(if using qcow).
I forget who is hosting it- I pulled clover from another repo- but reworked it into something useful.

-JazzMaster-

The AMD kext will have to be patched if using VFIO- which is even faster.
