Quick VMs with QEMU (UEFI Version)
This is a revision of the old page about making quick VMs for QEMU, it will include some BIOS stuff because some of the resources require it but mostly this is an attempt to demonstrate simple VM creation using QEMU without GUI tools that hide the details.
Creating an Image
To create an image file for your VM to use as a disk drive:
qemu-img create -f raw root.img.raw 64G
Or use a different format, qcow2 is probably the best bet:
qemu-img create -f qcow2 root.img.qcow2 64G
