The test is sporadically failing whenever we try to hotplug the vDPA
device we've just unplugged. This is causing the kernel to complain with
EBUSY because the device hasn't been released yet. This is happening
because the CI system is under very high load, therefore taking quite
some time to the host to update the state of this device.
The easy way to fix such issue is by increasing the sleep time between
the unplug and the replug.

(2) Adds a new integration test case for both x86_64 and AArch64 using

The test case does:
- Start a VM using direct kernel boot with 16 PCI segments and assign
the last PCI segment with a virtio-disk device.
- Check if the number of PCI host bridges equals to 16 after VM boots.
- Mount the virtio-disk device on the last PCI segment to the rootfs

For AArch64, now virtual IOMMU is only tested on FDT, not ACPI.
In the case of FDT, the behavior of IOMMU is a bit different with ACPI.
All the devices on the PCI bus will be attached to the virtual IOMMU,
except the virtio-iommu device itself. So these devices will all be
added to IOMMU groups, and appear in folder '/sys/kernel/iommu_groups/'.
The result is, on AArch64 IOMMU group '0' contains "0000:00:01.0" which
is the console device. But on X86, console device is not attached to
IOMMU. So the IOMMU group '0' contains "0000:00:02.0" which is the first

actual_mem is 2147483648 bytes
orig_balloon is 2147483648 bytes
total used free shared buff/cache available
Mem: 3.8Gi 2.1Gi 1.6Gi 0.0Ki 140Mi 1.6Gi
Swap: 0B 0B 0B
2. Run a command in guest to eat up 25G memory, and check again.
total_mem is 4294967296 bytes
actual_mem is 3121610752 bytes
deflated_balloon is 1173356544 bytes
total used free shared buff/cache available
Mem: 3.8Gi 1.2Gi 2.6Gi 0.0Ki 49Mi 2.5Gi

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.

When doing a direct kernel boot only have console=ttyS0 in the command
