Hello WoRLd!! ✋ KVEMU is an open-source key-value SSD emulator built on top of FEMU. This repository was opened to support KV-SSD researchers, and there are also plans to port various KV-SSD FTLs in the future. However, please note that the owner of this repository has already graduated and is maintaining it purely for leisure purposes, so responses might be a bit slow!

- Make sure you have installed necessary libraries for building QEMU. The dependencies can be installed by following instructions below:
cd ~
git clone https://github.com/chanyoung/kvemu.git
cd kvemu
mkdir build-femu
# Switch to the FEMU building directory
cd build-femu
# Copy femu script
cp ../femu-scripts/femu-copy-scripts.sh .
./femu-copy-scripts.sh .
# only Debian/Ubuntu based distributions supported
sudo ./pkgdep.sh- Compile & Install FEMU:
./femu-compile.shFEMU binary will appear as x86_64-softmmu/qemu-system-x86_64
- Prepare the VM image
mkdir -p ~/images/
cd ~/images
pip install gdown
gdown --id 1DJfaHnQpUn0pv0Tk2maNcmnwE8CFuKzN
gzip -d asplos.ubuntu.qcow2.gz- After guest OS is installed, boot it with
cd ~/kvemu/build-femu
./run-pink.sh
# Or
# ./run-lksv3.sh- After accessing the Guest OS, run the workload
# Password: liu
ssh liu@localhost -p 8080
cd uNVMe; sudo NRHUGE=256 ./script/setup.sh
cd app/fio_plugin
sudo ./fio-3.3 main/etc_load.fio
sudo ./fio-3.3 main/etc_ramp.fio
sudo ./fio-3.3 main/etc_run_20.fio
# Complete the execution by shutting down the VM
sudo shutdown -h now- After the workload execution is complete, you can analyze the generated log files using the extract script.
# Assume users are in the build-femu directory
./extract.sh log
