camkes-vm-examples

This repo contains a collection of example CAmkES applications that use the CAmkES VM project. This is a short description of the example applications and how to build them.

For detailed information about the CAmkES VM project and its dependencies see the documentation in the camkes-vm repo.

Building

To setup the camkes-vm-examples project we can use the repo tool to fetch the latest camkes-vm-examples-manifest:

# Create a directory for the project
mkdir camkes_vm_examples
cd camkes_vm_examples
# Fetch the project sources
repo init -u https://github.com/seL4/camkes-vm-examples-manifest.git
repo sync

To build an example VM application with CMake

# From the project root create a new folder to compile the project
mkdir build_vm
cd build_vm

# Invoke CMake using the shell script wrapper `init-build.sh` located in the root directory, passing the application you wish to compile as a command-line argument
# If no application is passed the optiplex9020 app will be built by default
../init-build.sh -DCAMKES_VM_APP=<APPLICATION_NAME>

# Invoke ninja to compile the example vm application
ninja

Then boot images/kernel-x86_64-pc99 and images/capdl-loader-experimental-image-x86_64-pc99 (or *.ia32-pc99 if built for 32-bit) with the multiboot boot loader of your choice.

Configuration

VM example applications are provied in this repo. The following is a short description of each vm application.

minimal

The minimal application is simple CAmkES VM application. The application is configured with:

1 Guest Linux VM: The Linux guest is a buildroot built image sourced from the the camkes-vm repo. The Linux images (rootfs and kernel) are defined in the CMakeLists.txt file of the minimal application. In the CMakeLists.txt file we are able to find that the rootfs and kernel images are added to the FileServer under the names "rootfs.cpio" and "bzimage" respectively.

optiplex9020

The optiplex9020 VM application is configured with:

2 Guest Linux VM's: The Linux guests are buildroot built images sourced from the the camkes-vm repo.
Cross VM Connectors: To demo the use of cross-vm connectors a series of shared dataports and events are established between vm0 and the StringReverse component. The StringReverse demo can be invoked from the command-line of vm0:
```
Welcome to Buildroot
buildroot login: root
Password:
\# string_reverse
[   19.739028] dataport received mmap for minor 1
[   19.743337] dataport received mmap for minor 2
hello
olleh
```

cma34cr_centos

The cma34cr_centos application is a more complex CAmkES VM configuration demonstrating the use of passthrough hardware. The cma34cr_centos application is configured with:

1 Guest Linux VM: The Linux guest images (bzimage and roofs.cpio) are located in the applications directory (cma34cr_centos/centos_linux), originally sourced from an i386 altarch CentOS-7 installation. Additionally the CentosOS installation should be on a flash drive passed-through to the cma34cr application. Further information regarding the Linux installation can be found in the applications README.
Cross VM Connectors: A series of shared dataports and events are established between vm0 and the StringReverse component.
Ethernet Driver, UDPSever, Echo, Firewall: A passthrough ethernet configuration demo. The guest VM is configured to use the Ethernet driver component through a virtio configuration.
Passthrough hardware storage (SATA/USB): A hardware configuration to boot the CentOS installation.

zmq_samples

The zmq_samples application demonstrates messaging between VMs using the ZeroMQ messaging library. See the README.md in its folder for more information.
