This release has been tracked through the v24.0 project.
virtio-iommu specification describes how a device can be attached by default
to a bypass domain. This feature is particularly helpful for booting a VM with
guest software which doesn't support virtio-iommu but still need to access
the device. Now that Cloud Hypervisor supports this feature, it can boot a VM
with Rust Hypervisor Firmware or OVMF even if the virtio-block device exposing
the disk image is placed behind a virtual IOMMU.
Multiple checks have been added to the code to prevent devices with identical
identifiers from being created, and therefore avoid unexpected behaviors at boot
or whenever a device was hot plugged into the VM.
Sparse mmap support has been added to both VFIO and vfio-user devices. This
allows the device regions that are not fully mappable to be partially mapped.
And the more a device region can be mapped into the guest address space, the
fewer VM exits will be generated when this device is accessed. This directly
impacts the performance related to this device.
A new serial_number option has been added to --platform, allowing a user to
set a specific serial number for the platform. This number is exposed to the
guest through the SMBIOS.
* Fix loading RAW firmware (#4072)
* Reject compressed QCOW images (#4055)
* Reject virtio-mem resize if device is not activated (#4003)
* Fix potential mmap leaks from VFIO/vfio-user MMIO regions (#4069)
* Fix algorithm finding HOB memory resources (#3983)
* Refactor interrupt handling (#4083)
* Load kernel asynchronously (#4022)
* Only create ACPI memory manager DSDT when resizable (#4013)
Deprecated features will be removed in a subsequent release and users should
plan to use alternatives
* The mergeable option from the virtio-pmem support has been deprecated
(#3968)
* The dax option from the virtio-fs support has been deprecated (#3889)

This change adds two fields to the Storage pb
FSGroup which is a group id that the runtime
specifies to indicate to the agent to perform a
chown of the mounted volume to the specified
group id after mounting is complete in the guest.
FSGroupChangePolicy which is a policy to indicate
whether to always perform the group id ownership
change or only if the root directory group id
does not match with the desired group id.
These two fields will allow CSI plugins to indicate
to Kata that after the block device is mounted in
the guest, group id ownership change should be performed
on that volume.

Let's bump the Cloud Hypervisor version to 5343e09e7b8db, as that brings
a few fixes we're interested in, such as:
* hypervisor, vmm: Handle TDX hypercalls with INVALID_OPERAND
- https://github.com/cloud-hypervisor/cloud-hypervisor/pull/3723
- This is needed for the TDX support on the cloud hypervisor driver,
which is part of this very same series.
* openapi: Update the PciBdf types
- https://github.com/cloud-hypervisor/cloud-hypervisor/pull/3748
- This is needed due to a change in a DeviceNode field, which would
cause a marshalling / demarshalling error when running with a
version of cloud-hypervisor that includes the TDX fixes mentioned
above.
* scripts: dev_cli: Don't quote $features_build
* scripts: dev_cli: Add --features option
- https://github.com/cloud-hypervisor/cloud-hypervisor/pull/3773
- This is needed due to changes in the scripts used to build Cloud
Hypervisor, which are used as part of Kata Containers CIs and
github actions.
Due to this change, we're also adapting the build scripts as part
of this very same commit.

We call it a ResourceController, and we make it not so Linux specific.
Now the Linux implementations is the cgroups one.

`enable_swap` option was added long time ago to add
`-realtime mlock=off` to the QEMU's command line.
Kata now supports QEMU 6, `-realtime` option has been deprecated and
`mlock=on` is causing unexpected behaviors in kata.
This patch removes support for `enable_swap`, `-realtime` and `mlock=`
since they are causing bugs in kata.
