We now reply on the value from '/sys/kernel/mm/ksm/shared_pages' to
validate our "--memory mergeable=on|off" option. For `mergeable=on`,
we are expecting to see more 'shared_pages' reported by the kernel when
we start more VMs with this option. For `mergeable=off`, we are
expecting the 'shared_pages' value to be always 0, as we are assuming
the rest of the system (in our CI) is not using mergeable memory.

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
The relevant part from the generated ASL for the MCRS method:

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
expected.

* 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.

The integration test validating that --serial off works correctly was
not properly written as it was using the FW, which by default would use
the kernel command line found in the EFI partition. Unfortunately, this
kernel command line was including "console=ttyS0", which causes the
kernel to try to write to the serial port, even if there's no serial
port being emulated.
The problem is, when no emulation of the serial port is provided, the
default value returned on 0x3f8 is 0, which makes the guest kernel think
that some data needs to be read.

The newly added integration test "test_snapshot_restore" is very
unstable, which causes our CI to fail on most pull requests, which is

Now that we have multiple virtio devices supporting snapshot and restore
operations, we can add a new integration test to validate the migration
feature works as expected.
The important part is virtio-net as it is used to ssh into the VM to
verify the VM has been restored in the proper state.
This test only works for virtio-mmio for now. Further support for
testing virtio-pci will be added once the virtio-pci transport layer
will support migration.

All vhost-user-blk, vhost-user-net and virtio-fs integration tests are
extended with memory resizing. The point is to validate that we can
hotplug some memory and keep these backends to work as expected.
Just a note that because memory resizing is not supported by mmio, we
limit these extensions to all non-mmio use cases.

Add a new id option to the VFIO hotplug command so that it matches the
VFIO coldplug semantic.
This is done by refactoring the existing code for VFIO hotplug, where
VmAddDeviceData structure is replaced by DeviceConfig. This structure is
the one used whenever a VFIO device is coldplugged, which is why it
makes sense to reuse it for the hotplug codepath.
