# Fuzzing in Cloud Hypervisor
|
||
|
|
|
||
|
|
Cloud Hypervisor uses [cargo-fuzz](https://github.com/rust-fuzz/cargo-fuzz) for fuzzing individual components.
|
||
|
|
|
||
|
|
The fuzzers are are in the `fuzz/fuzz_targets` directory
|
||
|
|
|
||
|
|
## Preparation
|
||
|
|
|
||
|
|
Switch to nightly:
|
||
|
|
|
||
|
|
````
|
||
|
|
rustup override set nightly
|
||
|
|
````
|
||
|
|
|
||
|
|
Install `cargo fuzz`:
|
||
|
|
|
||
|
|
```
|
||
|
|
cargo install cargo-fuzz
|
||
|
|
```
|
||
|
|
|
||
|
|
## Running the fuzzers
|
||
|
|
|
||
|
|
e.g. To run the `qcow` fuzzer using all available CPUs:
|
||
|
|
|
||
|
|
```
|
||
|
|
cargo fuzz run qcow -j `nproc`
|
||
|
|
```
|
||
|
|
|
||
|
|
## Adding a new fuzzer
|
||
|
|
|
||
|
|
```
|
||
|
|
cargo fuzz add <new_fuzzer>
|
||
|
|
```
|
||
|
|
|
||
|
|
