The MCRS method returns a 64-bit memory range descriptor. The
calculation is supposed to be done as follows:
max = min + len - 1
However, every operand is represented not as a QWORD but as combination
of two DWORDs for high and low part. Till now, the calculation was done
this way, please see also inline comments:
max.lo = min.lo + len.lo //this may overflow, need to carry over to high
max.hi = min.hi + len.hi
max.hi = max.hi - 1 // subtraction needs to happen on the low part
This calculation has been corrected the following way:
max.lo = min.lo + len.lo
max.hi = min.hi + len.hi + (max.lo < min.lo) // check for overflow
max.lo = max.lo - 1 // subtract from low part

Add the ability for cloud-hypervisor to create, manage and monitor a
pty for serial and/or console I/O from a user. The reasoning for
having cloud-hypervisor create the ptys is so that clients, libvirt
for example, could exit and later re-open the pty without causing I/O
issues. If the clients were responsible for creating the pty, when
they exit the main pty fd would close and cause cloud-hypervisor to
get I/O errors on writes.
Ideally the main and subordinate pty fds would be kept in the main
vmm's Vm structure. However, because the device manager owns parsing
the configuration for the serial and console devices, the information
is instead stored in new fields under the DeviceManager structure
directly.
From there hooking up the main fd is intended to look as close to
handling stdin and stdout on the tty as possible (there is some future
work ahead for perhaps moving support for the pty into the
vmm_sys_utils crate).
The main fd is used for reading user input and writing to output of
the Vm device. The subordinate fd is used to setup raw mode and it is
kept open in order to avoid I/O errors when clients open and close the
pty device.
The ability to handle multiple inputs as part of this change is
intentional. The current code allows serial and console ptys to be
created and both be used as input. There was an implementation gap
though with the queue_input_bytes needing to be modified so the pty
handlers for serial and console could access the methods on the serial
and console structures directly. Without this change only a single
input source could be processed as the console would switch based on
its input type (this is still valid for tty and isn't otherwise
modified).

The Windows image is quite large (about 20GiB), hence it takes some time
to copy it for every test in order to avoid potential corruption.
One way to mitigate that without compromising on safety between each
test is by using device mapper. By creating a read-only base, we ensure
the image won't be modified by any of the tests, and by creating one
snapshot for each test, we avoid copying the entire image each time.
A dedicated Copy On Write disk image is created to handle any change
that might be performed on the base image, letting the tests behave as

This commit enables the virtio-fs related integration test cases
for AArch64.
Note that to run virtio-fs cases, the host kernel should be
newer than v5.5.

This commit enables some mmio-related integration test cases on
AArch64, including:
* some vhost_user test cases
* virtio-blk test cases
* pmem test cases
Also this commit contains a bug fix in creating virtio-blk device.
Previously, when creating the FDT, the virtio-blk device was
labeled in the reverse order of address allocation.

Under high load, the VM might take some time to hotplug the disk after
the hotplug command has been issued. For this reason, let's put a 10s
sleep before checking for the presence of the new disk.

We want to give the time to the nested VM to be fully ready before we
check it's correctly setup. This involves 3 layers of virtualization
when running the CI on Azure, which added to the high load happening
because of the parallelization, adds up to the start up time.

As compiling without acpi (implied by mmio) means that the VM will
terminate on i8042 reset we cannot test the reboot.

The compiled AArch64 linux kernel by running `make` is in PE format
instead of vmlinux, vmlinux.pvh and bzImage format. Therefore we
need to add integration test for this case.

In order to differentiate tests that can be run in parallel versus
tests that must be run on their own, we move all tests into dedicated
modules.
The point is to avoid glitches in results that can be caused by the fact
that other tests (hence VMs) are running at the same time.

Move the CI to rely entirely on Ubuntu cloud images. It's worth noting
that both QCOW2 and RAW images from Ubuntu Focal Fossa have been
modified to include the tools needed from integration tests.
This means fio, iperf, iperf3, netcat and socat have been added to the
image. The snapd package have been fully removed as it was expecting the
support for squashfs (not present when using our own kernel from direct
kernel boot), which was causing some failures, and was preventing
cloud-init from terminating properly.

With QCOW disk images the space needed is greater than the size of the
iamge as any "zero" blocks in the image are allocated when they are
touched making the image bigger.
Here we add a threshold of 6GiB with added debugging messages to ensure
that there is sufficient disk space to run the tests.

Add a simple test to check that the data from the counters matches what

When a request is made to increase the number of vCPUs in the VM attempt
to reuse any previously removed (and hence inactive) vCPUs before
creating new ones.
This ensures that the APIC ID is not reused for a different KVM vCPU
(which is not allowed) and that the APIC IDs are also sequential.
The two key changes to support this are:
* Clearing the "kill" bit on the old vCPU state so that it does not
immediately exit upon thread recreation.
* Using the length of the vcpus vector (the number of allocated vcpus)
rather than the number of active vCPUs (.present_vcpus()) to determine
how many should be created.
This change also introduced some new info!() debugging on the vCPU
creation/removal path to aid further development in the future.
