HVM runtime system

Getting set up

First install prerequisites for building QEMU and Linux kernel (assuming CentOS/Fedora package names):

[you@you] sudo dnf install -y glib2-devel zlib-devel pixman-devel bison flex elfutils-libelf-devel openssl-devel glibc-static

Get the environment ready. This grabs, builds, and prepares recent copies of BusyBox (for the guest userspace), the Linux kernel (for the guest kernel), and QEMU (the VMM)

[you@host] make setup

Now build the initramfs, the guest linux user-space HVM utility, the guest Linux kernel driver, and the guest virtual disk image by running

[you@host] make 

The disk image will be mounted in the guest at /mnt. You can build the initramfs explicitly by running make initramfs and you can build the disk image explicitly by running make hdd. make by itself will invoke these automatically if they haven't been build yet.

You can run using QEMU:

[you@host] make run

You can run the guest user-space utility in the guest as follows:

[you@guest> /mnt/hvm-user
