6a9934d933 build: Fix vm-memory bump build error
A new version of vm-memory was released upstream which resulted in some
components pulling in that new version. Update the version number used
to point to the latest version but continue to use our patched version
due to the fix for #1258

22a2a99e5f acpi: Add hotplug numa node
virtio-mem device would use 'VIRTIO_MEM_F_ACPI_PXM' to add memory to NUMA
node, which MUST be existed, otherwise it will be assigned to node id 0,
even if user specify different node id.

According ACPI spec about Memory Affinity Structure, system hardware
supports hot-add memory region using 'Hot Pluggable | Enabled' flags.

8f0bf82648 io_uring: Add new feature gate
By adding a new io_uring feature gate, we let the user the possibility
to choose if he wants to enable the io_uring improvements or not.
Since the io_uring feature depends on the availability on recent host
kernels, it's better if we leave it off for now.

As soon as our CI will have support for a kernel 5.6 with all the
features needed from io_uring, we'll enable this feature gate
permanently.

917027c55b vmm: Rely on virtio-blk io_uring when possible
In case the host supports io_uring and the specific io_uring options
needed, the VMM will choose the asynchronous version of virtio-blk.
This will enable better I/O performances compared to the default
synchronous version.

This is also important to note the VMM won't be able to use the
asynchronous version if the backend image is in QCOW format.

1b1a2175ca vm-migration: Define the Snapshottable and Transportable traits
A Snapshottable component can snapshot itself and
provide a MigrationSnapshot payload as a result.

A MigrationSnapshot payload is a map of component IDs to a list of
migration sections (MigrationSection). As component can be made of
several Migratable sub-components (e.g. the DeviceManager and its
device objects), a migration snapshot can be made of multiple snapshot
itself.
A snapshot is a list of migration sections, each section being a
component state snapshot. Having multiple sections allows for easier and
backward compatible migration payload extensions.

Once created, a migratable component snapshot may be transported and this
is what the Transportable trait defines, through 2 methods: send and recv.

b2589d4f3f vm-virtio, vmm, vfio: Store GuestMemoryMmap in an Arc<ArcSwap<T>>
This allows us to change the memory map that is being used by the
devices via an atomic swap (by replacing the map with another one). The
ArcSwap provides the mechanism for atomically swapping from to another
whilst still giving good read performace. It is inside an Arc so that we
can use a single ArcSwap for all users.

Not covered by this change is replacing the GuestMemoryMmap itself.

This change also removes some vertical whitespace from use blocks in the
files that this commit also changed. Vertical whitespace was being used
inconsistently and broke rustfmt's behaviour of ordering the imports as
it would only do it within the block.

Since the Snapshotable placeholder and Migratable traits are provided as
well, the DeviceManager object and all its objects are now Migratable.

All Migratable devices are tracked as Arc<Mutex<dyn Migratable>>
references.

Keeping track of all migratable devices allows for implementing the
Migratable trait for the DeviceManager structure, making the whole
device model potentially migratable.

atomic.
The kvm-bindings and ioctls 0.2.0 and 0.4.0 crates come with a few API

587a420429 cargo: Update to the latest kvm-ioctls version
We need to rely on the latest kvm-ioctls version to benefit from the
recent addition of unregister_ioevent(), allowing us to detach a
previously registered eventfd to a PIO or MMIO guest address.

Because of this update, we had to modify the current constraint we had
on the vmm-sys-util crate, using ">= 0.1.1" instead of being strictly
tied to "0.2.0".

Once the dependency conflict resolved, this commit took care of fixing
build issues caused by recent modification of kvm-ioctls relying on
EventFd reference instead of RawFd.

2371325f9c vmm: api: Add HTTP server
The Cloud Hyper HTTP server runs a synchronous, multi-threaded
loop that receives HTTP requests and tries to call the corresponding
endpoint handlers for the requests URIs.

An endpoint handler will parse the HTTP request and potentially
translate it into and IPC request. The handler holds an notifier and an
mspc Sender for respectively notifying and sending the IPC payload to
the VMM API server. The handler then waits for an API server response
and translate it back into an HTTP response.
The HTTP server is responsible for sending the reponse back to the
caller.

The HTTP server uses a static routes hash table that maps URIs to
endpoint handlers.

df5058ec0a vm-virtio: Implement console size config feature
One of the features of the virtio console device is its size can be
configured and updated. Our first iteration of the console device
implementation is lack of this feature. As a result, it had a
default fixed size which could not be changed. This commit implements
the console config feature and lets us change the console size from
the vmm side.

During the activation of the device, vmm reads the current terminal
size, sets the console configuration accordinly, and lets the driver
know about this configuration by sending an interrupt. Later, if
someone changes the terminal size, the vmm detects the corresponding
event, updates the configuration, and sends interrupt as before. As a
result, the console device driver, in the guest, updates the console
size.

cargo vendor copies both of them into the vendor directory but
forces the build to use the one coming from the top level driven
requirement.

Although this is a waste of space, this is a cargo vendor limitation
that we have to live with for now.

Also, because the dependency onto linux-loader had to be updated,

c0be6642ad vmm: Leverage virtio-net to provide connectivity
This patch expand the device registration to add a new virtio-net
device in case the user provide the appropriate flag --net from the
command line.

If the flag is provided, the code will parse the TAP interface name
and the expected MAC address from the command line. The VM will be
connected to the provided TAP interface, and it will communicate the
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.

b67e0b3dad vmm: Use virtio-blk to support booting from disk image
After the virtio-blk device support has been introduced in the
previous commit, the vmm need to rely on this new device to boot
from disk images instead of initrd built into the kernel.

In order to achieve the proper support of virtio-blk, this commit
had to handle a few things:

  - Register an ioevent fd for each virtqueue. This important to be
    notified from the virtio driver that something has been written
    on the queue.

  - Fix the retrieval of 64bits BAR address. This is needed to provide
    the right address which need to be registered as the notification
    address from the virtio driver.

  - Fix the write_bar and read_bar functions. They were both assuming
    to be provided with an address, from which they were trying to
    find the associated offset. But the reality is that the offset is
    directly provided by the Bus layer.

  - Register a new virtio-blk device as a virtio-pci device from the
    vm.rs code. When the VM is started, it expects a block device to
    be created, using this block device as the VM rootfs.
