7fe399598d vmm: device_manager: Map MMIO regions to the guest correctly
To correctly map MMIO regions to the guest, we will need to wait for valid
MMIO region information which is generated from 'PciDevice::allocate_bars()'
(as a part of 'DeviceManager::add_pci_device()').

1dfe4eda5c vmm: Prevent "internal" identifiers being used by user
For devices that cannot be named by the user use the "__" prefix to
identify them as internal devices. Check that any identifiers provided
in the config do not clash with those internal names. This prevents the
user from creating a disk such as "__serial" which would then cause a
failure in unpredictable manner.

6e101f479c vmm: Ensure hotplugged device identifier is unique
Whenever a device (virtio, vfio, vfio-user or vdpa) is hotplugged, we
must verify the provided identifier is unique, otherwise we must return
an error.

Particularly, this will prevent issues with identifiers for serial,
console, IOAPIC, balloon, rng, watchdog, iommu and gpio since all of
these are hardcoded by the VMM.

The device identifiers generated from the DeviceManager were not
guaranteed to be unique since they were not taking the list of
identifiers provided through the configuration.

By returning the list of unique identifiers from the configuration, and
by providing it to the DeviceManager, the generation of new identifiers
can rely both on the DeviceTree and the list of IDs from the
configuration.

e70bd069b3 vmm: Load kernel asynchronously
Start loading the kernel as possible in the VM in a separate thread.
Whilst it is loading other work can be carried out such as initialising
the devices.

The biggest performance improvement is seen with a more complex set of
devices. If using e.g. four virtio-net devices then the time to start the
kernel improves by 20-30ms. With the simplest configuration the
improvement was of the order of 2-3ms.

fdeb4f7c46 Revert "vmm, openapi: Token Bucket fields should be uint64"
This reverts commit 87eed369cd.

The reason we're reverting this is that OpenAPI Specification[0] doesn't
know how to deal with unsigned types. :-/

Right now the best to do is keep it as it's, as an int64, and try to fix
OpenAPI, or even switch to swagger, as the latter knows how to properly
deal with those.  However, switching to swagger is far from being an 1:1
transition and will require time to experiment, thus reverting this for
now seems the best approach.

bf9f79081a vmm: Only create ACPI memory manager DSDT when resizable
If using the ACPI based hotplug only memory can be added so if the

Instead of defining some very generic resources as PioAddressRange or

PciBar in order to make things clearer. This allows the code for being
more readable, but also removes the need for hard assumptions about the
MMIO and PIO ranges. PioAddressRange and MmioAddressRange types can be
used to describe everything except PCI BARs. BARs are very special as
they can be relocated and have special information we want to carry

into a dedicated function, we can write some unit tests to validate it
properly achieves what we expect.

Adding the "tdx" feature to the unit tests, otherwise it wouldn't get
tested.
