Problems: Networking is not working properly

I workarounded this not using the tun/tap interfacing:

replace line 46 with this:

-netdev user,id=net0 -device e1000-82545em,netdev=net0 \

Then connect to the internet using DHCP (Automatic IP Address Assignment)

Its not like having a tun/tap device, but it is good for most cases.

I will update this gist frequently

Trying to find out the best configuration! :)

And solving as many problems as possible

When I run ./osx-qemu-kvm_install.sh yosemite 15G Yosemite.iso . 4096 it gives me the response:

Changing directory to: . 

I downloaded osx-qemu-kvm_install.sh file and changed mode by +x.
I'm on Ubuntu 14.04 and kernel 4.9.0-040900-generic version

Yup, my own fault, I used /bin/sh instead of /bin/bash (strange situation since /bin/sh is a symlink to /bin/bash...)
Anyway,try now :P

Hi. How to boot ?

I do exactly what you do. But the black window that pops up QEMU

The bootloader clearly says you to hit enter to boot without customizing kernel command line parameters.

Hi Developer's,
I run the script osx-qemu-kvm_install.sh
and get this error message

Is there something changed at https://raw.githubusercontent.com?

yes, kholia replaced the kernel image with a new one, I will replace it ASAP

Hi Stefano

I changed your script to reflect the fact that Kohila is now using enoch_rev2898_boot. Now, however, the script aborts, saying it cannot find Install_macOS_10.12.6_Sierra.iso, yet it it sitting the same directory as the script. Any idea what I am doing wrong?

Regards
Fergus

I copied the iso file (renamed to Install_macOS_10.12.6_Sierra.iso) to the ~/.qemu/ folder where boot-macOS.sh file is. And then I reran the kvm_install script. I got rid of the iso not found error but then I got another error: "Cannot find boot file: '/System/Library/Kernals/kernel' ".
Any thoughts?

I have the same problem as @bhaveekdesai. "Cannot find boot file: '/System/Library/Kernals/kernel' ". I tried doing it with an ISO as suggested in the guide as well as building my own UniBeast installer on USB. Same results.

Guys this is not a help desk, sorry, check if Kholia is available for support,

Cannot find boot file: '/System/Library/Kernals/kernel'

This problem is not related with my script, @brianwoo is having the same problem using UniBeast.

Let me know

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.
