KVM OSX Guest 10.11 (El Capitan) with Clover

  • Some notes about this approach:

    • An OSX Installer USB drive for Install OS X El Capitan is created
    • Clover is then installed on the USB drive
    • Clover Configurator is then run on the USB drive
    • The USB drive contents are copied to the VM host
    • VNC is used to connect to the guest UI
    • The qxl virtual video device is used (part of the standard kvm qemu install)
    • No video card PCI passthrough is used
    • At then of the install OSX Screen Sharing is turned on
  • VM Host Ubuntu 15.10 (x86_64) server

  • Standard kvm, qemu packages installed

  • All Ubuntu updates applied (2016-03-06)

  • VM images and resources in /vm/2016-03-06

  • Supporting MacBook Air running OSX 10.11.3 used to create USB drive

  • All OSX updated applied (2016-03-06)

Screen Resolution

A quick note about screen resolution:

  • OVMF and Clover screen sizes must match otherwise the screen will appear mangeled or distorted.
  • For purposes of these instructions a resolution of 800x600 will be used.

TODO: Change OVMF and Clover resolutions to 1024x768 or 1280x1024

Step 1 OVMF

  • On Linux kvm host, build OVMF, please see:

https://gist.github.com/gordonturner/85dcc321d2099d610e67

  • Copy bios.bin:
sudo cp ./Build/OvmfX64/DEBUG_GCC49/FV/OVMF.fd /vm/2016-03-06/bios.bin

Step 2 Get Apple SMC osk Value

  • On OS X, running on Apple hardare, to get the SMC osk value please see:

https://gist.github.com/gordonturner/c33bcc935e32f9fa6695

  • NOTE: 2016-03-06 The value appears to be a constant string

  • Reference:

http://www.osxbook.com/book/bonus/chapter7/tpmdrmmyth/

Step 3 Create Install USB Drive

  • On an Apple computer running OS X, create install USB drive.

  • Run Disk Utilty

  • If on 10.11 or later:

    • Select the USB device (not a partition of the device) in the left pane
    • Click Partition tab, ensure there is a single partition, click Cancel or create single partition
    • With the USB device selected, click Erase
    • Set Name to Untitled, Format to OS X Extended (Journaled), Scheme to GUID Partition Map
    • Click Erase button
    • Confirm Partition Map is set to GUID Partition Map
  • If on 10.10 or earler:

    • Select the USB device (not a partition of the device) in the left pane
    • Click Partition tab
    • In Partition Layout, select 1 Partition
    • Confirm Partition Map is set to GUID Partition Map
    • Click Options button, select GUID Partition Table, click OK
    • Change Name to Untitled
    • Change Format type to Mac OS Extended (Journaled)
    • Click Apply, then Partition
  • Once partitioning is complete, click Done

  • Close Disk Utility

  • For El Capitan, default Application location, run:

sudo /Applications/Install\ OS\ X\ El\ Capitan.app/Contents/Resources/createinstallmedia \
--volume /Volumes/Untitled \
--applicationpath /Applications/Install\ OS\ X\ El\ Capitan.app \
--nointeraction
  • For El Capitan, if you have moved the Install OS X El Capitan.app (which is common to prevent it being deleted) run:
export MOVED_LOCATION=~/Documents/Disk\ Images/Apple\ OS\ X/10.11\ El\ Capitan
sudo "$MOVED_LOCATION"/Install\ OS\ X\ El\ Capitan.app/Contents/Resources/createinstallmedia \
--volume /Volumes/Untitled \
--applicationpath "$MOVED_LOCATION"/Install\ OS\ X\ El\ Capitan.app \
--nointeraction

Step 4: Run Clover on Install USB drive

  • On an Apple computer running OS X, download Clover from:

https://sourceforge.net/projects/cloverefiboot/files/latest/download

  • NOTE: 2016-03-06 Current download was Clover_v2.3k_r3354.zip

  • Download Clover_v2.3k_r3354.zip

  • Unzip Clover_v2.3k_r3354.zip

  • Run Clover_v2.3k_r3354.pkg

  • Click Continue until Installation Type screen

  • On Installation Type screen, click Change Install Location...

  • On Destination Select screen, select the Install USB drive as destination, click Continue

  • Back on Installation Type screen, click Customize

  • On Custom Install on "..." screen select Install for UEFI booting only

    • This should automatically select Install Clover in the ESP
  • On Custom Install on "..." screen, select Themes, BootCamp (or your theme of choice)

  • On Custom Install on "..." screen, select Drivers64UEFI, DataHubDxe-64

  • On Custom Install on "..." screen, click Install

  • Install should take about 3 min on USB 3 device

  • When complete, click Close

  • Two volumes should be mounted when complete:

    • EFI
    • Install OS X El Capitan
  • Leave volumes mounted

Step 5: Download Files

  • After complete, eject the USB drive.

Step 7 Linux Copy USB Drive to Disk Image on kvm Host

  • Either dd the USB drive on OSX or use dd on the Linux KVM host, these instructions are for Linux.

  • Login to KVM host and run tail on the kernel log to determine device name:

tail -f /var/log/kern.log
  • Plugin the USB drive
  • Observe the device name:
Feb 20 14:40:58 kvm2 kernel: [13158.166032] usb 4-1.4: new high-speed USB device number 7 using ehci-pci

Feb 20 14:41:00 kvm2 kernel: [13159.908483] sd 6:0:0:0: [sdb] Attached SCSI removable disk
  • In this example sdb is the device
  • Run dd, takes about 10 min on USB 3 device:
sudo dd if=/dev/sdb of=/vm/2016-03-06/clover-usb-disk.dd

Step 8 Create Disk and Set Parameters

  • On Linux kvm host, create a disk image:
sudo qemu-img create -f qcow2 /vm/2016-03-06/osx-disk0.qcow2 200G
  • Ignore MSR readout on host by VM:
sudo su -
echo 1 > /sys/module/kvm/parameters/ignore_msrs
  • NOTE: This appears to reset after a hard reboot, may need to be run as part of a script.

Step 9 qemu Start

  • NOTE: Due to expired certificates used to sign the installation packages, it is necessary during installation to set the date back and remove the network card. After installation is complete, the time can be set and network card added back.

  • NOTE: Set the SMB_OSK_VALUE_HERE with the value from Step 2 Get Apple SMC osk Value

  • On Linux kvm host, start qemu:

sudo qemu-system-x86_64 \
\
-rtc clock=vm,base=2016-01-01T16:01:21 \
\
-m 4096 \
-enable-kvm \
-cpu core2duo,vendor=GenuineIntel \
-rtc base=localtime \
-smbios type=2 \
-machine q35,accel=kvm,usb=off,vmport=off \
-bios /vm/2016-03-06/bios.bin \
-smp 4,sockets=1,cores=2,threads=2 \
-device isa-applesmc,osk="SMB_OSK_VALUE_HERE" \
\
-device i82801b11-bridge,id=pci.1,bus=pcie.0,addr=0x1e \
-device pci-bridge,chassis_nr=2,id=pci.2,bus=pci.1,addr=0x1 \

-device ide-hd,bus=ide.2,drive=drive-sata0-0-2,id=sata0-0-2,bootindex=1 \
\
-drive file=/vm/2016-03-06/osx-disk0.qcow2,if=none,media=disk,id=drive-sata0-0-0,format=qcow2 \
-device ide-hd,bus=sata0.0,drive=drive-sata0-0-0,id=sata0-0-0 \
\
-usb \
-device usb-mouse \
-device usb-kbd \
-serial stdio \
-device qxl-vga,id=video0,ram_size=67108864,vram_size=67108864,vgamem_mb=16 \
-vnc :1

Step 9 Clover Start

  • Connect a VNC client to Linux kvm host
  • Tunnel 5901 over ssh:
ssh -L 5910:127.0.0.1:5901 KVM_HOST
  • Connect a VNC client to 127.0.0.1 5710

  • At Clover boot screen, choose Boot OS X Install from OS X Install OS X El Capitan

Step 10 Installation

  • During install, first use Disk Utility to configure the QEMU drive.

  • NOTE: Using vnc to perform the install, there is a frustrating bug with vnc and the OS X installer, the mouse.

  • It is possible to use the Tab key to select and Spacebar to select on most of the inputs, but in some situations it becomes a bit of a game to move the mouse in the guest to the button.

  • Once installed and connecting over vnc directly to the guest this is not an issue.

Step 11 Post Installation

  • System Preferences, Sharing, enable Screen Sharing and set password

  • System Preferences, Energy Saving, Computer sleep set to Never

  • System Preferences, Energy Saving, Display sleep set to Never

  • Connect to the guest directly, rather then through the host.

EFI Disk Image Manipulation

  • Rather then constantly editing the USB drive then dd'ing and copying the image around, it is possible to directly edit the disk image

  • First, create a mount points, this step only has to happen once:

sudo mkdir /media/loop
sudo mkdir /media/efi
  • Run fdisk to determine the offset of the efi partition:
parted /vm/clover-usb-disk.dd

  • NOTE: The offset, in this case 20480

  • Next, mount the EFI System Partition:

sudo mount -o rw,loop,offset=20480 /vm/clover-usb-disk.dd /media/loop
  • Make changes, ie to edit config.plist:
sudo vi /media/loop/EFI/CLOVER/config.plist
  • Unmount the partition:
sudo umount /media/loop

Using fdisk

  • Run fdisk to determine the offset of the efi partition:
fdisk -l  /vm/clover-usb-disk.dd 
  • Output:
