Install QEMU on OSX

QEMU requires brew in OSX, so we need to install brew first.

Installing Brew

To install brew we need to have the developer tools enabled in our system. In order to install those tools, we have two options.

1. Download Xcode form the AppStore
2. In your terminal run the following command: xcode-select --install

• Download and install VirtualBox.
• Download the CoreOS ISO
• Create a new VM in VirtualBox
  • For the OS, Other Linux, 64-bit should be fine
  • Give the VM 1gb of memory, like your physical hardware has.
  • Create a disk of whatever size you want. I made a VMDK file that could expand dynamically up to 8gb.
• Mount the ISO in the VM
  • Right click on the VM and click settings
• Go to the storage tab
