507912385a vmm: Ensure that PIO and MMIO exits complete before pausing
As per this kernel documentation:

      For KVM_EXIT_IO, KVM_EXIT_MMIO, KVM_EXIT_OSI, KVM_EXIT_PAPR, KVM_EXIT_XEN,
      KVM_EXIT_EPR, KVM_EXIT_X86_RDMSR and KVM_EXIT_X86_WRMSR the corresponding
      operations are complete (and guest state is consistent) only after userspace
      has re-entered the kernel with KVM_RUN.  The kernel side will first finish
      incomplete operations and then check for pending signals.

      The pending state of the operation is not preserved in state which is
      visible to userspace, thus userspace should ensure that the operation is
      completed before performing a live migration.  Userspace can re-enter the
      guest with an unmasked signal pending or with the immediate_exit field set
      to complete pending operations without allowing any further instructions
      to be executed.

Since we capture the state as part of the pause and override it as part
of the resume we must ensure the state is consistent otherwise we will
lose the results of the MMIO or PIO operation that caused the exit from
which we paused.

b3ca1d90e9 vmm: Stop dirty logging only if it has been started
Now that we introduced a separate method to indicate when the migration

carry an implicit meaning as they can focus entirely on the dirty log
being started or stopped.

For that reason, we can now safely move stop_dirty_log() to the code
section performing non-local migration. It makes only sense to stop
logging dirty pages if this has been started before.

a45e458c50 vm-migration: Add start_migration() to Migratable trait
In order to clearly decouple when the migration is started compared to
when the dirty logging is started, we introduce a new method to the
Migratable trait. This clarifies the semantics as we don't end up using
start_dirty_log() for identifying when the migration has been started.
And similarly, we rely on the already existing complete_migration()
method to know when the migration has been ended.

A bug was reported when running a local migration with a vhost-user-net
device in server mode. The reason was because the migration_started
variable was never set to "true", since the start_dirty_log() function
was never invoked.

0dafd47a7c vmm: openapi: Remove mention to net fds
While cloud-hypervisor does support receiving the file descriptors of a
tuntap device, advertising the fds structure via the openAPI can lead to
misinterpretations of what can and what should be done.

An unadvertised consumer will think that they could rather just set the
file descriptors there directly, or even pass them as a byte array.
However, the proper way to go in those cases would be actually sending
those via send_msg(), together with the request.

As hacking the openAPI auto-generated code to properly do this is not
*that* trivial, and as doing so during a `create VM` request is not
supported, we better not advertising those.

Please, for more details, also check:

4e46a1bc3c vmm: api: Support multiple fds with add-net
Based on the latest code from the micro-http crate, this patch adds the
support for multiple file descriptors to be sent along with the add-net
request. This means we can now hotplug multiqueue network interface to
the VM.

ea0729c016 vmm: acpi: Create ACPI tables for TDX
The way to create ACPI tables for TDX is different as each table must be
passed through the HOB. This means the XSDT table is not required since
the firmware will take care of creating it. Same for RSDP, this is
firmware responsibility to provide it to the guest.

That's why this patch creates a TDX dedicated function, returning a list
of Sdt objects, which will let the calling code copy the content of each
table through the HOB.

When using this code on the Kata Containers side we'd be hit by a non

method to initialise the `tuntap` device the code would be treated as if
using `--net tap` (which is a valid use-case).
