The runtime will crash when trying to resize memory when memory hotplug
is not allowed.
This happens because we cannot simply set the hotplug amount to zero,
leading is to not set memory hotplug at all, and later then trying to
access the value of a nil pointer.

When booting the TDX kernel with `tdx_disable_filter`, as it's been done
for QEMU, VirtioFS can work without any issues.
Whether this will be part of the upstream kernel or not is a different
story, but it easily could make it there as Cloud Hypervisor relies on
the VIRTIO_F_IOMMU_PLATFORM feature, which forces the guest to use the
DMA API, making these devices compatible with TDX.
See Sebastien Boeuf's explanation of this in the
3c973fa7ce208e7113f69424b7574b83f584885d commit:
"""
By using DMA API, the guest triggers the TDX codepath to share some of
the guest memory, in particular the virtqueues and associated buffers so
that the VMM and vhost-user backends/processes can access this memory.

An implementation of semi-automating the backporting
process.
This implementation has two steps:
1. Checking whether any associated issues are marked as bugs
If they do, mark with `auto-backport` label
2. On a successful merge, if there is a `auto-backport` label and there
are any tags of `backport-to-BRANCHNAME`, it calls an action that
cherry-picks the commits in the PR and automatically creates a PR to
those branches.
This action uses https://github.com/sqren/backport-github-actionFixes#3618

To make cgroup v1 and v2 works well, I use `cgroups::cgroup` in
`Container` to manager cgroup now. `CgroupManager` in rustjail has some
drawbacks. Frist, methods in Manager traits are not visiable. So we need
to modify rustjail and make them public. Second, CgrupManager.cgroup is
private too, and it can't be serialized. We can't load/save it in
status file. One solution is adding getter/setter in rustjail, then
create `cgroup` and set it when loading status. In order to keep the
modifications to a minimum in rustjail, I use `cgroups::cgroup`
directly. Now it can work on cgroup v1 or v2, since cgroup-rs do this
stuff.

To plug drop-in support into existing config-loading code in a robust
way, more specifically to create a single point where this needs to be
handled, load_from_file() and load_raw_from_file() were refactored.
Seeing as the original implemenations of both functions were identical
apart from adjust_config() calls in load_from_file(), load_from_file()
was reimplemented in terms of load_raw_from_file().
Fixes #4771

The central function being added here is load() which takes a path to a
base config file and uses it to load the base config file itself, find
the corresponding drop-in directory (get_dropin_dir_path()), iterate
through its contents (update_from_dropins()) and load each drop-in in
turn and merge its contents with the base file (update_from_dropin()).
Also added is a test of load() which mirrors the corresponding test in
the golang runtime (TestLoadDropInConfiguration() in config_test.go).

This is the core functionality of merging config file fragments into the
base config file. Our TOML parser crate doesn't seem to allow working
at the level of TomlConfig instances like BurntSushi, used in the Golang
runtime, does so we implement the required functionality at the level of
toml::Value trees.
Tests to verify basic requirements are included. Values set by a base
config file and not touched by a subsequent drop-in should be preserved.
Drop-in config file fragments should be able to change values set by the
base config file and add settings not present in the base. Conversion
of a merged tree into a mock TomlConfig-style structure is tested as
well.

It would be nice to use `versions.yaml` for the maintainability.
Previously, we have been specified the `libseccomp` and the `gperf` version
directly in this script without using the `versions.yaml` because the current
snap workflow is incomplete and fails.
This is because snap CI environment does not have kata-cotnainers repository
under ${GOPATH}. To avoid the failure, the `rootfs.sh` extracts the libseccomp
version and url in advance and pass them to the `install_libseccomp.sh` as
environment variables.

Highlights from the Cloud Hypervisor release v26.0:
**SMBIOS Improvements via `--platform`**
`--platform` and the appropriate API structure has gained support for supplying
OEM strings (primarily used to communicate metadata to systemd in the guest)
**Unified Binary MSHV and KVM Support**
Support for both the MSHV and KVM hypervisors can be compiled into the same
binary with the detection of the hypervisor to use made at runtime.
**Notable Bug Fixes**
* The prefetchable flag is preserved on BARs for VFIO devices
* PCI Express capabilties for functionality we do not support are now filtered
out
* GDB breakpoint support is more reliable
* SIGINT and SIGTERM signals are now handled before the VM has booted
* Multiple API event loop handling bug fixes
* Incorrect assumptions in virtio queue numbering were addressed, allowing
thevirtio-fs driver in OVMF to be used
* VHDX file format header fix
* The same VFIO device cannot be added twice
* SMBIOS tables were being incorrectly generated
**Deprecations**
Deprecated features will be removed in a subsequent release and users should
plan to use alternatives.
The top-level `kernel` and `initramfs` members on the `VmConfig` have been
moved inside a `PayloadConfig` as the `payload` member. The OpenAPI document
has been updated to reflect the change and the old API members continue to
function and are mapped to the new version. The expectation is that these old
versions will be removed in the v28.0 release.
**Removals**
The following functionality has been removed:
The unused poll_queue parameter has been removed from --disk and
equivalent. This was residual from the removal of the vhost-user-block
spawning feature.
