What about an El Capitan VM?

• peter_sm – wouldn’t have gotten this working without his expertise and teamwork!
• The authors in the references below – thanks for the guides.

Prerequisites:

• Working unRAID 6 Server
• Bridge Enabled (Settings -> Network Settings -> Setup Bridge: Yes & Bridge name: br0)
• Windows or Linux VM (This is not needed to install OS X but would be good to practice setting up a VM before attempting this)
• 64 Character OSK Key (You will need a real Mac to get this and I will NOT provide one). Read the references below for more information on this.
• chameleon_svn2510_boot (See info below)
• Mac Files (contains “chameleon_svn2510_boot” & “org.chameleon.boot.plist”)

Step 01 – Creating a bootable Yosemite ISO:

1. Download the Yosemite.app from the Mac App Store.
2. Open Terminal and do the following:

# Mount the installer image
hdiutil attach /Applications/Install\ OS\ X\ Yosemite.app/Contents/SharedSupport/InstallESD.dmg -noverify -nobrowse -mountpoint /Volumes/install_app

# Convert the boot image to a sparse bundle
hdiutil convert /Volumes/install_app/BaseSystem.dmg -format UDSP -o /tmp/Yosemite

# Increase the sparse bundle capacity to accommodate the packages
hdiutil resize -size 8g /tmp/Yosemite.sparseimage

# Mount the sparse bundle for package addition
hdiutil attach /tmp/Yosemite.sparseimage -noverify -nobrowse -mountpoint /Volumes/install_build

# Remove Package link and replace with actual files
rm /Volumes/install_build/System/Installation/Packages
cp -rp /Volumes/install_app/Packages /Volumes/install_build/System/Installation/

# Copy Yosemite installer dependencies
cp -rp /Volumes/install_app/BaseSystem.chunklist /Volumes/install_build/BaseSystem.chunklist
cp -rp /Volumes/install_app/BaseSystem.dmg /Volumes/install_build/BaseSystem.dmg

# Unmount the installer image
hdiutil detach /Volumes/install_app

# Unmount the sparse bundle
hdiutil detach /Volumes/install_build

# Resize the partition in the sparse bundle to remove any free space (If this step does not work, try manually typing in this command, WordPress keeps messing up the format of the special characters)
hdiutil resize -size `hdiutil resize -limits /tmp/Yosemite.sparseimage | tail -n 1 | awk ‘{ print $1 }’`b /tmp/Yosemite.sparseimage

# Convert the sparse bundle to ISO/CD master
hdiutil convert /tmp/Yosemite.sparseimage -format UDTO -o /tmp/Yosemite

# Remove the sparse bundle
rm /tmp/Yosemite.sparseimage

# Rename the ISO and move it to the desktop
mv /tmp/Yosemite.cdr ~/Desktop/Yosemite.iso

#Add KERNEL

1. Mount Yosemite ISO by double clicking Yosemite.iso
2. Download Pacifist
3. With Pacifist browse to /System/Installation/Packages/Essentials.pkg
4. Extract the folder & file (Kernels/kernel) to /System/Library/ on the Yosemite.iso
5. ***Disregard this step: this is a note /System/Library/Kernels/kernel

Step 02 – Mac OS X Installation Disc Image:

1. ssh into unRAID
2. move to the directory where you want your Mac OS X image to live.
3. cd /mnt/cache/vm_images/default/
4. qemu-img create -f raw Yosemite.img 120G

Step 03 – Get chameleon_svn2510_boot:

1. Copy the file linked above to your cache drive and you’re done with step 03 or:
2. Go to this site: http://www.insanelymac.com/forum/files/download/59-chameleon-23-svn/
3. Download the file: i386_v2510.zip
4. Extract the file called boot
5. Rename boot to chameleon_svn2510_boot
6. Move this file to your unRAID server (I moved mine to: /mnt/cache/vm_images/extra)

Step 04 – Install OS X:

1. Go to the KVM tab in unRAID -> Add VM -> Template: XML Expert -> Copy the config below & fill in the RED text with your own settings:
2. <domain type='kvm' xmlns:qemu='http://libvirt.org/schemas/domain/qemu/1.0'>

3. **NOTE** If your CPU is AMD you must add the following to the above XML config (above the </qemu:commandline> line) :
   <qemu:arg value=’-cpu’/>
   <qemu:arg value=’core2duo,vendor=GenuineIntel’/>
4. Now start the VM and click on “VNC Remote”
5. Now you should see the Chameleon boot prompt:
6. You can use -v for a verbose boot which can aid in troubleshooting. If you get a kernel panic here, If your terminal is filled with usb-kbd: warning: key event queue full and the keyboard doesn’t respond, just try again. While the keyboard works reliably once OS X boots, it sometimes has problems on the Chameleon boot prompt. Hopefully the installer should just start right up.
   
7. Continue with the installer and start up Disk Utility to partition your drive to Mac HD (The mouse is going to be laggy until we get everything installed) Hint: Move the mouse faster to get the cursor to move farther.
   
8. Close Disk Utility and install to the disk partition you just created.
   
9. The installer will reboot and put you back on the Chameleon prompt. Choose the (Installer) Mac HD partition to continue with the install.
   
10. The install will continue. I skipped setting up an Apple ID and registering. Now you should have a mostly functional Mac OS X installation!
    
11. Now lets get Absolute Mouse Positioning working:
    Most KVM guests can make use of the tablet device to synchronize the position of the mouse with it’s position over the VNC window. OS X, unfortunately, does not support this device. If you enable OS X’s internal screen sharing and use it in place of QEMU’s VNC server then mouse positioning works perfectly. Go to “System Preferences” -> “Sharing” -> enable “Screen Sharing” -> “Computer Settings…” -> add a password.
    
12. Then connect to the Mac using TightVNC and the mouse positioning should be perfect. Here are the TightVNC “Options…” settings:
    
13. Now go to “Computer” -> “Mac HD” -> create a new folder called “Extra”.
    
14. Open a text editor and save the following as org.chameleon.boot.plist (or copy the file linked above into your created Extra folder).
15. <?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
<key>Timeout</key>
<string>5</string>
<key>EthernetBuiltIn</key>
<string>Yes</string>
<key>PCIRootUID</key>
<string>1</string>
</dict>

16. Shut down the VM
17. Edit your XML file and remove the following:
18. <qemu:arg value=’-drive’/>
    <qemu:arg value='ide-drive,bus=ide.1,drive=MacDVD'/>
<qemu:arg value='-drive'/>
<qemu:arg value='id=MacDVD,if=none,snapshot=on,file=/mnt/cache/vm_images/installer/Yosemite.iso'/>
19. Now start the VM and you should be able to log into the app store.
20. The virtio network driver does not work on Yosemite as of this post. I have been using the e1000 driver.

Step 05 – USB Passthrough:

1. Disclaimer: Your motherboard & CPU must support  VT-x & VT-d and be enabled in the bios or you will not be able to passthrough PCI devices.
2. Normally you could just add each USB device individually with the following:
3. <hostdev mode=’subsystem’ type=’usb’ managed=’no’>
   <source>
   <vendor id=’0x0500’/>
   <product id=’0x14f7/>
   </source>
   </hostdev>
4. Due to the line <key>PCIRootUID</key> <string>1</string> in the org.chameleon.boot.plist file this will not work. (without the PCIRootUID line the App Store will not accept your username and password)
5. If you want USB Passthrough to work you will need to passthrough an entire USB PCI Controller
6. See Guide

Step 06 – GPU Passthrough:

1. Disclaimer: Your motherboard & CPU must support  VT-x & VT-d and be enabled in the bios or you will not be able to passthrough PCI devices.
2. You will probably want to try and get a GPU working, but that is easier said than done. Mac’s are very picky about which GPU’s work. Google is your friend.
3. I bought a Sapphire Radeon HD 6450 that works out of the box without any modifications. (This is rare for the GPU card to work without modifications / graphic kexts / graphic injectors)
4. XML Code for the Radeon GPU:
5. <qemu:arg value=’-device’/>
   <qemu:arg value=’ioh3420,bus=pcie.0,addr=1c.0,multifunction=on,port=1,chassis=1,id=root.1’/>
   <qemu:arg value=’-device’/>
   <qemu:arg value=’vfio-pci,host=02:00.0,bus=root.1,addr=00.0,multifunction=on,x-vga=on’/>
   <qemu:arg value=’-device’/>
   <qemu:arg value=’vfio-pci,host=02:00.1,bus=root.1,addr=00.1’/>
6. Remove the following from your XML
7. <graphics type=’vnc’ port=’-1′ autoport=’yes’ websocket=’-1′ listen=’0.0.0.0′ keymap=’en-us’>
   <listen type=’address’ address=’0.0.0.0’/>
   </graphics>
   <video>
   <model type=’vmvga’ vram=’16384′ heads=’1’/>
   <address type=’pci’ domain=’0x0000′ bus=’0x00′ slot=’0x01′ function=’0x0’/>
   </video>
8. Your millage will vary.

EXTRA:

1. If you want a larger VNC screen do the following:
   1. Add this to the bootloader config in /Extra/org.chameleon.boot.plist:
   2. <key>Graphics Mode</key>
      <string>1440x900x32</string>
