Requirements

• A modern Linux distribution. E.g. Ubuntu 18.04 LTS 64-bit.

• QEMU > 2.11.1

• A CPU with Intel VT-x / AMD SVM support is required

• A CPU with SSE4.1 support is required for macOS Sierra

• A CPU with AVX2 support is required for macOS Mojave

Note: Older AMD CPU(s) are known to be problematic. AMD FX-8350 works but Phenom II X3 720 does not. Ryzen processors work just fine.

Installation Preparation

ignore_msrs and unsafe_interrupts required to bypass serial console loading for verbose boot testing

• KVM may need the following tweak on the host machine to work.

  # echo 1 > /sys/module/kvm/parameters/ignore_msrs
  
  
  

  To make this change permanent, you may use the following command.

  
  kvm.conf
  ----------------------
  options kvm ignore_msrs=1

$ sudo cp kvm.conf /etc/modprobe.d/kvm.conf

sudo -i echo "export EDITOR=nano" >> /root/.bashrc

#where user is your username echo "export EDITOR=nano" >> /home/user/.bashrc

* Install QEMU and other packages.

sudo apt-get install qemu uml-utilities virt-manager dmg2img git wget

This step may need to be adapted for your Linux distribution.




### * respawned fork from kholia to reflect updates for Catalina

### * WIP implement bash script to deploy virsh based virt-manager install package management driven install qemu
<br>
<br>

qemu-img convert BaseSystem.dmg -O raw Catalina-installer.iso

<br>

<br>
<br>

### * clover-r5070.iso.imac131.svga.iso (partial q35 acceleration mount as SATA qcow2 not as a CDROM iso "files encapsulated in .iso based container")

(iso modified from nick sherlock's iso again from kholia's patch -> resoloution fixed with this iso ^ for kholia's OVMF patch from https://www.nicksherlock.com/2019/10/installing-macos-catalina-10-15-on-proxmox-6/ )

### * to mount to edit
### * where nbd5 is choosen mount point (where qemu-nbd is installed, where kernel is built with NBD as a block device)

modprobe nbd max_part=8 qemu-nbd --connect=/dev/nbd5 clover-r5070.iso.catalina.iso mkdir /mnt/catalina-5070 mount /dev/nbd5p1 /mnt/catalina-5070 cd /mnt/catalina-5070 ls EFI/CLOVER/kexts/Other # <-- for custom kexts

• at first run during verbose boot the serial output is scrambled, after about 15 seconds the display auto corrects to the proper wrapped resoloution,
