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.

Just updating the documentation regarding the pre-creation of a tap
interface supporting multiqueue, by adding what the cloud-hypervisor
--net parameter should look like.

With the latest version of virtiofsd, some changes have been made
to the socket path parameter. This needs to be updated in the cloud
hypervisor codebase, so that our CI keeps running correctly.

The cache= option from the virtiofsd backend is meant to be used
depending on how the user wants to use the guest page cache. For most
use cases, we want to bypass the guest page cache to reduce the guest
memory footprint, which is why "cache=none" should be the default.
"cache=always" is the other option when the user wants to do something
specific by using the guest page cache, but should not be the default
anymore.

With latest kernel, virtio-fs mount command has been simplified, and
this needs to be applied everywhere in our tests and documentation.

The documentation was out of date since the URL to download virtiofsd
binary was not valid anymore. Instead, the updated documentation now
describe how to build virtiofsd from source.

Update all references to the new repository locations. Many of these will
redirect however the one used for the hypervisor-fw binary does not so
this is required to allow the builds to pass.

This commit introduces a dedicated document describing the device model
supported by cloud-hypervisor VMM.
It needs to be updated anytime a new device will be added in the future.

The cloud-hypervisor supports the DAX shared region for better virtio-fs
performances, but it was not updated in the documentation. This commit
takes care of this and also update the mount command since it changed
with virtio-fs v0.3.

Based on recent update of the cloudguest image used by Cloud Hypervisor,
we identified some missing or incorrect details in the instructions.
This patch is here to fix those.

This patch extends the existing virtual IOMMU documentation, explaining
how the use of huge pages can drastically improve the VM boot time.
Particularly, how in case of nested VFIO, the impact is significant and
the rationales behind it.

Having the virtual IOMMU created with --iommu is one thing, but we also
need a way to decide if a VFIO device should be attached to the virtual
IOMMU or not. That's why we introduce an extra option "iommu" with the
value "on" or "off". By default, the device is not attached, which means
"iommu=off".

This patch introduces a specific documentation for the virtual IOMMU
device. This is important to understand what the use cases are for this
new device and how to properly use it with virtio devices.

Having the virtual IOMMU created with --iommu is one thing, but we also
need a way to decide if a virtio-blk device should be attached to this
virtual IOMMU or not. That's why we introduce an extra option "iommu"
with the value "on" or "off". By default, the device is not attached,
which means "iommu=off".
One side effect of this new option is that we had to introduce a new
option for the disk path, simply called "path=".

This is a quick guide on how to create a custom Clear Linux image based
on the official tooling provided by Clear Linux. If for any reason, the
image we are using is missing some interesting bundles that are packaged
by Clear Linux, this documentation will be the guide on how to proceed.

The cargo interaction with the .cargo/config does not meet our
requirements.
Regardless of .cargo/config explicitly replacing our external sources
with vendored ones, cargo build will rely first on Cargo.lock to update
its local source cache. If a dependency has been push forced, build
fails because of our top level Cargo.toml description.
This prevents us from actually pinning dependencies, which defeats the
vendoring purpose.
We're removing vendoring for now, until we understand it better.
