We need the host IPC for sharing eventfds with KVM, and the host network
for VFIO.
We also enforce the no-seccomp setting on the container, to overcome any
potential filtering set by our container's Ubuntu base.

All our tests must be run as root and thus the build directory is owned
by root after we run any of them.
Start another container to fix all permissions whenever we're done with
our tests.

By default we will run as root inside the container, which means all the
build artifacts will be owned by root. That prevents us from properly

We don't need to force the cargo-audit install, we can check if it's

The script is a development tool that runs all commands in a dedicated
container. This allows for containerized, isolated and reproducible
builds and CI runs.
The script supports the following command:
* build: Build Cloud Hypervisor binaries (debug and release)
* build-container: Build the container used by the script
* tests: Run unit, cargo and integration tests
$ ./scripts/dev_cli.sh help
Cloud Hypervisor dev_cli.sh
Usage: dev_cli.sh <command> [<command args>]
Available commands:
build [--debug|--release] [-- [<cargo args>]]
Build the Cloud Hypervisor binaries.
--debug Build the debug binaries. This is the default.
--release Build the release binaries.
tests [--unit|--cargo|--all]
Run the Cloud Hypervisor tests.
--unit Run the unit tests.
--cargo Run the cargo tests.
--integration Run the integration tests.
--all Run all tests.
build-container [--type]
Build the Cloud Hypervisor container.
--dev Build dev container. This is the default.

When the CI runs in a brand new VM, there's no problem with the validity
of the images as they just got downloaded from the Azure bucket.
In case of a user who runs the CI locally, while doing some debug, he
might provision the images with cloudinit at some point, and later try
to run the CI based on these same images. What happens is that the CI
might randomly fail because the provisioning will not happen again as
it already happened.
This patch ensures the CI to fail early and show an error message to
notify the user about the validity of the images, based on their
sha1sum.

Virtio-fs maintainers recently updated the virtiofsd daemon through
their official branch on Gitlab. It includes fixes that were needed for
cloud-hypervisor to work correctly with it.
Jenkinsfile needs to be updated since the virtiofsd build requires both
libseccomp and libcap-ng to be present on the system.
One thing to notice, because the latest branch introduced a change
regarding libfuse behavior, the counterpart patch has been added to the
custom kernel branch "virtio-fs-virtio-iommu".

Because the resources on the amount of worker nodes we can have access
to through Travis is limited, we offload the burden of running all tests
related to Cargo inside the Azure VM directly.
This will have the positive effect of stopping the build very early in
case something goes wrong during the Cargo testing.

In order to validate that multiple devices can be passed through and

The setcap tool is unusual in its behaviour in that it will process each
parameter separately and abort if one of the parameters is invalid (e.g.
after a symlink.) But any previous parameters will be correctly
processed. This means that depending on the generated test binary name
an invalid entry might occur before it and thus abort the setcap.
Fix to only setcap on the test binary by excluding the other files.
Because the binary name is based on a hash the PR that introduced this
version worked but once merged the hash changed and broke the build.

In order to validate the new virtio-fs daemon written in Rust is
behaving correctly, a new integration test has been added. Important to
note that for now, only a test with cache=none and dax=off can be added
since the daemon does not support shared memory region yet.
The long term goal being to replace virtiofsd with vhost_user_daemon
once it will reach parity regarding the supported features.
