This repo wraps a range of applications that can be used for testing and evaluating the Nephele cloning solution for unikernel-based VMs. The applications run on Mini-OS and Unikraft unikernels, but also as Linux processes. Based on the build configuration, a binary image can run one or more of the following:
- counter
- simple UDP server used in the instantiation and memory consumption microbenchmarks of Nephele
- simple TCP server
- measure-fork was used for measuring the
fork()duration for different memory sizes in the Nephele paper - memory-overhead measures the overhead added by Nephele for memory accesses after cloning a parent guest
- files tests the cloning support for 9pfs
- children is a fork server that waits for incoming requests to clone
Our modified Mini-OS can be built
together with the cloning applications by setting the CLONING_APPS_DIR and
APP environment variables. For a thorough example, please check the
build.sh
script in our experiments repo. To
build a Mini-OS image, run the following command in the Mini-OS tree:
make <other parameters ..> CLONING_APPS_DIR=<path> APP=server-udp
The current tree is created also as a regular Unikraft application tree,
providing the files needed for building it as Unikraft application:
Config.uk, Makefile.uk and Makefile.unikraft. Thus the following command
will built the binary image for Unikraft guests:
make -f Makefile.unikraft
You should use the Unikraft kernel modified for Nephele and the libraries (e.g., pthread-embedded, newlib, lwip, mimalloc) provided by our Unikraft-related repositories. The build.sh script in our experiments repo builds both Mini-OS and Unikraft images by running:
./build.sh guests
To build for Linux, run:
make -f Makefile.linux
