PoC: KVM

The Motivation
Running Kernel-based Virtual Machine (KVM) on my local machine instead of:

• Hyper-V
• VMWare
• Proxmox
• virsh (Virtualization Shell)

Use on-board Linux apps and utilities only; prefer APT distros such as Debian or Ubuntu.

VM Installation

Installation Debian from ISO

• VM Installer01

• VM Installer02

• VM Installer05

• VM Installer06

• VM Installer07

• VM Installer08

• VM Installer09

• VM Installer10

• VM Installer11

• VM Installer12

Installation Win10 VM (former vhdx file)

• Install01

• Install02

• Install03

• Install04

• Win10 in running state

Installation Win11 VM (from iso, no registration)

• Using the official Windows 11 ISO
• Install Windows 11 but without network, this way no registration takes place

• When asked for network connectivity then press Shift + F10
• Then type:

OOBE\BYPASSNRO

• After finishing the setup, shutdown

root@ts01:/data/vmtemplate# virsh shutdown win11

• It is required to install the network driver, but first detach the current iso image:

root@ts01:/data/vmtemplate# virsh detach-disk win11 sdb --config
Disk detached successfully

• Attach the network interface

root@ts01:/data/vmtemplate# virsh attach-interface \
 --domain win11 \
 --type bridge \
 --source br0 \
 --model virtio \
 --config
Interface attached successfully

• Check:

root@ts01:/data/vmtemplate# virsh domiflist win11
 Interface   Type     Source   Model    MAC
-----------------------------------------------------------
 -           bridge   br0      virtio   52:54:00:16:25:ee

• Download driver disk:

cd /var/lib/libvirt/images
wget https://fedorapeople.org/groups/virt/virtio-win/direct-downloads/latest-virtio/virtio-win.iso

• Attach driver disk:

virsh attach-disk win11 \
 /var/lib/libvirt/images/virtio-win.iso \
 sdb \
 --type cdrom \
 --mode readonly \
 --targetbus sata \
 --config

• Start VM

root@ts01:/data/vmtemplate# virsh start win11
Domain 'win11' started

• From Device Manager, Install missing Driver from the new disk: NetKVM\w10\amd64

• Install

• Stop VM
• Detach Helper Disk

root@ts01:/data/iso# virsh detach-disk win11 sdb --config
Disk detached successfully

• Finished

Installation Mac OS (EXPERIMENTAL)

The following section is experimental by AI created

• Repository Initialization

The foundation of the project relies on the OSX-KVM repository, which provides the OpenCore bootloader configurations and scripts to fetch official macOS assets.

# Clone the project repository
git clone --depth 1 https://github.com/kholia/OSX-KVM.git
cd OSX-KVM

• Preparation Tasks

Before configuring the Virtual Machine, specific scripts must be run to acquire the macOS installation media.

• Fetching macOS Assets

Run the Python script to download the Recovery image directly from Apple's servers.

./fetch-macOS-v2.py

Note: You will be prompted to choose a version (e.g., Ventura, Sonoma). This creates a "BaseSystem.dmg" file.

• Image Conversion

The downloaded DMG must be converted into a raw image format that KVM can easily mount.

dmg2img -i BaseSystem.dmg BaseSystem.img

• Virtual Disk Creation

Create the virtual hard drive where the OS will be permanently installed.

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

• Host-Level Optimizations

To prevent Kernel Panics during the boot process, the KVM module must be configured to ignore unhandled Model Specific Registers (MSRs).

• Permanent MSR Fix

Edit or create the KVM configuration file on the host:

sudo nano /etc/modprobe.d/kvm.conf

Add the following configuration line:

options kvm ignore_msrs=1

To apply the change without rebooting the host:

echo 1 | sudo tee /sys/module/kvm/parameters/ignore_msrs

• Virtual Machine XML Configuration

The VM is defined in Libvirt using a modified XML template. Key adjustments ensure the guest OS perceives the hardware as a compatible Apple-Intel machine.

• CPU Masking and OSK

The CPU must be set to 'Penryn' with an Intel vendor ID mask to bypass Apple's hardware checks.

<cpu mode='custom' match='exact' check='none'>
  <model fallback='allow'>Penryn</model>
  <feature policy='require' name='vendor_id' value='GenuineIntel'/>
</cpu>

Note: The OSK (Apple System Management Controller Key) must be included in the QEMU command-line arguments section of the XML.

• Storage and Firmware Paths

Ensure the following paths point to your actual local files:

• Loader: /home/vmadmin/OSX-KVM/OVMF_CODE_4M.fd
• NVRAM: /home/vmadmin/OSX-KVM/OVMF_VARS-1024x768.fd
• OpenCore: /home/vmadmin/OSX-KVM/OpenCore/OpenCore.qcow2
• BaseSystem: /home/vmadmin/OSX-KVM/BaseSystem.img
• Target Disk: /home/vmadmin/OSX-KVM/mac_hdd_ng.img

• Filesystem Permissions

Libvirt runs as a separate system user and requires explicit access to files located in a user's home directory.

# Enable directory traversal
chmod +x /home/vmadmin
chmod +x /home/vmadmin/OSX-KVM

# Change ownership to the Libvirt-QEMU user
sudo chown libvirt-qemu:kvm /home/vmadmin/OSX-KVM/mac_hdd_ng.img
sudo chown libvirt-qemu:kvm /home/vmadmin/OSX-KVM/BaseSystem.img
sudo chown libvirt-qemu:kvm /home/vmadmin/OSX-KVM/OpenCore/OpenCore.qcow2

• The Installation Process

1. Format: Use Disk Utility inside the "macOS Base System" to erase the virtual disk as APFS with a GUID Partition Map.
2. Install: Select "Reinstall macOS" and target the newly formatted drive.
3. Bootloader Logic: Upon rebooting, the OpenCore picker will show a "macOS Installer" icon. This must be selected for all intermediate reboots (usually 3-4 times).
4. Final Boot: Once the installer icon disappears, select the name of your formatted drive (e.g., "MAConKVM") to complete the user setup.

This will setup a new VM with:

• Name: vm-bookworm
• OS Debian 13 (Trixy)
• Disk: /data/vmstorage/vm-bookworm.qcow2
• 2CPU/2GB-RAM
• Network Bridged

root@ts01:/data/vmstorage# virt-install \
 --name vm-bookworm \
 --memory 2048 \
 --vcpus 2 \
 --cpu host-passthrough \
 --os-variant debian12 \
 --disk path=/data/vmstorage/vm-bookworm.qcow2,bus=virtio,discard=unmap \
 --network bridge=br0,model=virtio \
 --graphics spice,listen=0.0.0.0 \
 --channel spicevmc \
 --autoconsole none \
