Hermitux: a unikernel binary-compatible with Linux applications

For general information about HermiTux's design principles and implementation, please read the paper and Daniel Chiba's MS thesis.

Quick start

The easiest way to try HermiTux is with Docker:

docker pull olivierpierre/hermitux
docker run --privileged -it olivierpierre/hermitux

Prerequisites

  • Recommended system: Ubuntu 18.04/16.04 or Debian 10/9 (GlibC support is not assured on other distributions)
  • Debian/Ubuntu packages:
sudo apt update
sudo apt install git build-essential cmake nasm apt-transport-https wget \
	libgmp-dev bsdmainutils libseccomp-dev python
echo "deb [trusted=yes] https://dl.bintray.com/hermitcore/ubuntu bionic main" \
	| sudo tee -a /etc/apt/sources.list
sudo apt update
sudo apt install binutils-hermit newlib-hermit pte-hermit gcc-hermit \
	libomp-hermit libhermit
  • For Debian 9 and Ubuntu 16.04, you may also need to install a recent version of libmpfr to use the hermit toolchain:
wget https://www.mpfr.org/mpfr-current/mpfr-4.0.2.tar.bz2
tar xf mpfr-4.0.2.tar.bz2
cd mpfr-4.0.2
./configure
make -j`nproc`
sudo make install
sudo ldconfig
  • Finally for Ubuntu 16.04 you need a recent version of cmake:
# It is probably better to uninstall any existing installation:
sudo apt remove cmake
wget https://github.com/Kitware/CMake/releases/download/v3.14.3/cmake-3.14.3.tar.gz
tar xf cmake-3.14.3.tar.gz
cd cmake-3.14.3
./configure
make -j`nproc`
make install

Build

  1. Clone the repo
git clone https://github.com/ssrg-vt/hermitux
  1. Install everything with the bootstrap script:
cd hermitux
./bootstrap.sh
  1. Test an example application, for example NPB IS:
cd apps/npb/is
# let's compile it as a static binary:
gcc *.c -o is -static
# let's launch it with HermiTux:
sudo HERMIT_ISLE=uhyve HERMIT_TUX=1 ../../../hermitux-kernel/prefix/bin/proxy \
	../../../hermitux-kernel/prefix/x86_64-hermit/extra/tests/hermitux is

# Now let's try with a dynamically linked program:
gcc *.c -o is-dyn
# We can launch it like that (for now it needs a bit more RAM):
sudo HERMIT_ISLE=uhyve HERMIT_TUX=1 HERMIT_MEM=1G \
	../../../hermitux-kernel/prefix/bin/proxy \
	../../../hermitux-kernel/prefix/x86_64-hermit/extra/tests/hermitux \
	../../../musl/prefix/lib/libc.so is-dyn
