On AArch64, device hotplug can be enabled with ACPI. Therefore,
this commit enables the hotplug test case for following devices:
- PCI bar reprogramming
- virtio-disk
- virtio-net
- macvtap
- virtio-vsock
- virtio-pmem: Works with the latest reference kernel
- virtio-fs: Works with the latest reference kernel

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
disk.

The new test_virtio_balloon() is to verify if the 'deflate_on_oom'

total_mem is 4294967296 bytes
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
Swap: 0B 0B 0B

A new method has been introduced for WindowsGuest, that would poll on
the SSH connection and try to execute a test command. When successfull,
the polling stops and the guest is considered finished boot. The
downside of this method is that the network setup is needed always even
if the test doesn't use network, however it complies with the behavior
of other tests. I also observe a bit more stability on the local test
run, however it still appears to be a resource issue so some sporadic
fails are possible on a slower machine.

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.

When an SSH command fails we want to be able to see, via a panic() why
and where it failed. Replace use of .unwrap_or_default() from SSH
command calls to ensure that we can see the location of the panic.
Also enhance the existing SSH output code to show the error if there is
one.

The boot time for direct kernel boot based tests is significantly
quicker than booting via the firmware and stock kernel as it triggers a
reboot during the boot process due to the initrd handling.
Signed-off-by: Rob Bradford <robert.bradford@intel.com>
When doing a direct kernel boot only have console=ttyS0 in the command
line if we are explicitly testing the serial output. The default
behaviour is `--serial null` so this output will not be visible but will
trigger a KVM exit for every byte which is very costly when running
under nested virtualization.

Tests not ported include 1) the ones that start guest VMs without

Instead of waiting blindly with fixed amount of sleeping time, we can
use the `wait-timeout` crate to explicitly wait VM shutdown (with a
timeout). It can reduces the execution time of some tests
substantially. Also, this patch increases the `shutdown` timeout for
'test_reboot', which should fix the recent sporadic failures on this

This is a new integration test running Windows as a guest with Cloud

Important to note that because this test generates lots of logs, it

As discussed in #1707, the `vcpu` thread can be stalled when using

The goal of this commit is to rename the existing NUMA option 'id' with
'guest_numa_id'. This is done without any modification to the way this
option behaves.
The reason for the rename is caused by the observation that all other
parameters with an option called 'id' expect a string to be provided.
Because in this particular case we expect a u32 representing a proximity
domain from the ACPI specification, it's better to name it with a more
explicit name.

Rather than using a credible TestBlock to capture the test assertions
instead use a catch_unwind block to catch the panic and turn
it into a Result<>.
If block panicked or the child binary had non-zero exit then, and only
then, print out the child output.
This results in a clearer test output with no interleaving.
Currently only test_counters is ported to this methodology to
demonstrate its use.

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.
