dc31db478a ci: Fix virtio-fs tests
The virtiofsd daemon takes a bit of time creating and listening on the
socket. By adding 10s timeout, we make sure the vhost-user socket has
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.

Fixes #182

08ed88c8d1 tests: Remove potential sources of nested panics
panic()ing after a panic() has already been recovered by the credibility
test system (i.e. after an aver! has failed) results in an abort which
triggers SIGILL.

Adjust the SSH based commands to generate a Result<...,Error> which we
then either propagate through the test block. Or if the function is
directly being evaluated in an aver! macro call .unwrap_with_default()
(or .unwrap_or() in the case where the default would be wrong.)

658c076eb2 linters: Fix clippy issues
Latest clippy version complains about our existing code for the

- `...` range patterns are deprecated
- lint `clippy::const_static_lifetime` has been renamed to

74225ab5b3 config: Add option dax and cache_size to virtio-fs
In order to support the more performant version of virtio-fs, that is
the one relying on a shared memory region between host and guest, we
introduce two new parameters to the --fs device.

The "dax" parameter allows the user to choose if he wants to use the
shared memory region with virtio-fs. By default, this parameter is "on".

The "cache_size" parameter allows the user to specify the amount of
memory that should be shared between host and guest. By default, the
value of this parameter is 8Gib as advised by virtio-fs maintainers.

Note that dax=off and cache_size are incompatible.

294c26bfb7 vmm: Add virtio-pmem support to cloud-hypervisor
This patch plumbs the virtio-pmem device to the VMM. By adding a new
command line option "--pmem", we can now expose some persistent memory
to the guest OS, backed by the provided source.

The point of having such support in cloud-hypervisor is to be able to
share some memory between the host and the guest as DAXable.
One interesting use case is to boot directly from an image passed
through virtio-pmem, instead of going through virtio-blk. This can
allow good performances while avoiding the guest cache, which would
prevent the VM memory footprint from growing too much.

on the input provided by the user, while the latter is the
result of the parsing of every options.

VmCfg is meant to be consumed by the vmm specific code, and
it is also a fully public structure so that it can directly

5934f30fde vmm: Add support for letting the VMM create the TAP interface
Until now, the only way to get some networking with cloud-hypervisor
was to let the user create a TAP interface first, and then to provide
the name of this interface to the VMM.

This patch extend the previous behavior by adding the support for the
creation of a brand new TAP interface from the VMM itself. In case no
interface name is provided through "tap=<if_name>", we will assume
the user wants the VMM to create and set the interface on its behalf,
no matter the value of other parameters (ip, mask, and mac).
In this same scenario, because the user expects the VMM to create the
TAP interface, he can also provide the associated IP address and subnet
mask associated with it. In case those values are not provided, some
default ones will be picked.

No matter the value of "tap", the MAC address will always be set, and
if no value is provided, the VMM will come up with a default value for
it.

MAC address to the virtio-net driver.

If the flag is not provided, the VM will not register any virtio-net
device, therefore it will not have any connectivity with the host.

1270d09301 cloud-hypervisor: Add --disk option to provide VM rootfs
Based on the new virtio-blk support, this commit allows any user to
specify a --disk option in order to select the rootfs it wants to
use for the VM.

For now it assumes the partition 3 /dev/vd3 is the one where we can
find the rootfs.

1853b350ee cloud-hypervisor: Add devices crate
Based on the Firecracker devices crate from commit 9cdb5b2.

It is a trimmed down version compared to the Firecracker one, to remove
a bunch of pulled dependencies (logger, metrics, rate limiter, etc...).
