requirements

cpu with virtualization technology
virtualization enable on bios
kvm module enable on linux
disk space for creating virtual disk

verify your cpu

to confirm your computer have virtualization enable:

grep -E '(vmx|svm)' /proc/cpuinfo

offline install

for offline installation you need a mac to create the ventura img, on mac install command line tools:

xcode-select --install

download the install assistant package:

download this script to create the offline ventura dmg:

https://raw.githubusercontent.com/kholia/OSX-KVM/f66a236a4a08411b61daef064dc0833594eded59/scripts/create_dmg_ventura.sh

set execute permissions to file:

chmod +x create_dmg_ventura.sh

execute the file on your mac:

./create_dmg_ventura.sh

archlinux

install packages:

pacman -S git virt-manager dmg2img base-devel networkmanager --noconfirm

enable and start libvirt service:

systemctl enable libvirtd && systemctl start libvirtd

add your user to libvirt group:

gpasswd -a username libvirt

redhat

for redhat or any redhat derivatives:

https://wiki.vidalinux.org/index.php/Howto_KVM

ubuntu

install universe repo:

sudo add-apt-repository universe
sudo apt update

install packages:

sudo apt install dmg2img qemu-kvm libvirt-daemon-system libvirt-clients bridge-utils virt-manager git build-essential -y

enable and start libvirt service:

sudo systemctl enable libvirtd && systemctl start libvirtd

add your user to libvirt group:

sudo gpasswd -a username libvirt

create bridge interface

create the bridge interface:

nmcli connection add type bridge autoconnect yes con-name br0 ifname br0

add device to bridge:

nmcli connection add type bridge-slave autoconnect yes con-name br0-eth0 ifname eth0 master br0

add ip address to bridge interface:

nmcli connection modify br0 ipv4.address 192.168.75.15 ipv4.method manual ipv4.gateway 192.168.75.1 ipv4.dns 4.2.2.1,4.2.2.2

active bridge interface:

nmcli connection up br0

configure kvm

download osx-kvm git repo:

git clone --depth 1 --recursive https://github.com/kholia/OSX-KVM.git

fetch osx ventura baseimg:

cd OSX-KVM
./fetch-macOS-v2.py

select number six to download ventura:

1. High Sierra (10.13)
2. Mojave (10.14)
3. Catalina (10.15)
4. Big Sur (11.7) - RECOMMENDED
5. Monterey (12.6)
6. Ventura (13)

convert basesystem dmg to img:

dmg2img -i BaseSystem.dmg BaseSystem.img

create qemu hard drive for osx installation:

qemu-img create -f qcow2 mac_hdd_ng.img 128G

edit OpenCore-Boot.sh and change ALLOCATED_RAM:

ALLOCATED_RAM="8192"

edit OpenCore-Boot.sh and change cpu threads:

-smp 4,threads="$CPU_THREADS",cores="$CPU_CORES",sockets="$CPU_SOCKETS"

edit OpenCore-Boot.sh and change OVMF_VARS.fd archive:

-drive if=pflash,format=raw,file="$REPO_PATH/$OVMF_DIR/OVMF_VARS.fd"

edit OpenCore-Boot.sh and change sata for virtio in the following line:

-drive id=MacHDD,if=none,file="$REPO_PATH/mac_hdd_ng.img",if=virtio,format=qcow2
#-device ide-hd,bus=virtio,drive=MacHDD

edit OpenCore-Boot.sh and change vga driver:

#-monitor stdio
#-device VGA,vgamem_mb=128
-vga virtio
