hoyeong / KVM OSX Guest 10.11 (El Capitan) with Clover.md
Created February 4, 2017 12:51 — forked from gordonturner/KVM OSX Guest 10.11 (El Capitan) with Clover.md

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)
