Anatol Belski b02df13af9 doc: Stop advertizing QCOW usage at some places in doc 
Replacing QCOW mentions with other viable options. There is still
docs/custom-image.md which talks about creating QCOW, however it
might be more convenient to be touched when the actual changes
are indeed there.

Related to #1985.

Fuzzing in Cloud Hypervisor

Cloud Hypervisor uses 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 block fuzzer using all available CPUs:

cargo fuzz run block -j `nproc`

Adding a new fuzzer

cargo fuzz add <new_fuzzer>

Inspiration for fuzzers can be found in crosvm
