df2570a472 resources: Simplify kernel config filename
Since we only keep one single version of the kernel config file in our

03398532dc ci: Bump to kernel 5.6-rc4
The kernel version is updated from 5.5-rc1 to 5.6-rc4, including the
updated kernel config file.

The kernel branch contains virtio-fs, virtio-iommu and virtio-mem
patches that are not upstream yet. It also contains one fix for
virtio-vsock which will be merged upstream in the next release.

0223cf8c2b ci: Update ClearLinux image
A new ClearLinux image has been uploaded to the Azure storage account.
It is based off of the ClearLinux cloudguest image 31310 version, with
three extra bundles added to it.

First bundle is curl, which adds the curl binary to the image, second
bundle is iperf, adding the iperf binary to the image, and third bundle
is sysadmin-basic to include utility like netcat.

The image is 2G in size.

694da82691 ci: Make the integration tests fail if images are not valid
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.

Fixes #112

a40a70ad86 ci: Rely on latest virtiofsd version
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".

8fe5a43d9d tests: Only setcap on test binary
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.

The virtiofsd daemon takes a bit of time creating and listening on the

been properly created before the VMM tries to connect to it.

Also, the daemon needs cap_dac_override capabilities to access debugfs
filesystem.

Last thing, both virtio-fs and virtio-pmem tests were slightly different
from the others since they were not explicitly killing cloud-hypervisor
and virtiofsd processes once the test was done.
