qenv is a small utility for rapidly getting up and running for doing emulated nvme/ocssd device testing.
Create the file config. Nothing is required in the file, but see the example
in examples/config if you want to modify any defaults.
If you do not have a base image to boot from, you can generate a reference Arch
Linux environment. Modifying MIRROR in refenv/http/install.sh will probably
speed up the process, so consider changing it to a mirror close to you.
To build the image go into the refenv directory and type make. The
resulting image is in refenv/output-qemu/packer-qemu. Copy it to
img/base.img (the default location of the base image).
See the documentation in the source for full instructions on how to configure the emulated device.
Create a zero-sized backing image:
qemu-img create -f raw img/ocssd.img 0
Run with the ocssd device, an emulated iommu and debugging enabled:
./run --ocssd --enable-iommu --debug
Or with a custom kernel image:
./run --ocssd --enable-iommu --debug --kernel bzImage
Connect to the running VM using:
./ssh
