We need to validate that OpenAPI YAML definition is not broken by each

provided by OpenAPITools, as it allows us to validate the definition
with one simple command.

Now that Cargo tests are being run on the worker node directly, we can
leave the bare minimum in Travis, which is taking care of the release
deployment.
Signed-off-by: Sebastien Boeuf <sebastien.boeuf@intel.com>
Because the resources on the amount of worker nodes we can have access
to through Travis is limited, we offload the burden of running all tests
related to Cargo inside the Azure VM directly.
This will have the positive effect of stopping the build very early in
case something goes wrong during the Cargo testing.

In order to let the CLI and the HTTP API behave the same regarding the
FsConfig structure, this patch defines some default values for
num_queues, queue_size and the cache_size.
num_queues is set to 1, queue_size is set to 1024, and cache_size is set
to Some(8G) which means that DAX is enabled by default with a shared
region of 8GiB.

When consumer of the HTTP API try to interact with cloud-hypervisor,
they have to provide the equivalent of the config structure related to
each component they need. Problem is, the Rust enum type "Option" cannot
be obtained from the OpenAPI YAML definition.
This patch intends to fix this inconsistency between what is possible
through the CLI and what's possible through the HTTP API by using simple
types bool and int64 instead of Option<u64>.

In order to validate that multiple devices can be passed through and

Previously the device setup code assumed that if no IOAPIC was passed in
then the device should be added to the kernel irqchip. As an earlier
change meant that there was always a userspace IOAPIC this kernel based
code can be removed.
The accessor still returns an Option type to leave scope for
implementing a situation without an IOAPIC (no serial or GED device).
This change does not add support no-IOAPIC mode as the original code did
not either.

This commit ensures device's PCI config space is being written after
MSI/MSI-X interrupts have been enabled/disabled. In case of MSI, when
the interrupts are enabled through VFIO (using VFIO_DEVICE_SET_IRQS),
the MSI Enable bit in the MSI capability structure found in the PCI
config space is disabled by default. That's why when the guest is
enabling this bit, we first need to enable the MSI interrupts with
VFIO through VFIO_DEVICE_SET_IRQS ioctl, and only after we can write
to the device region to update the MSI Enable bit.

Some physical address bits may become reserved in page table when SME

violation page fault in this case due to write these reserved bits to 1

The KVM_SET_GSI_ROUTING ioctl is very simple, it overrides the previous
routes configuration with the new ones being applied. This means the
caller, in this case cloud-hypervisor, needs to maintain the list of all
interrupts which needs to be active at all times. This allows to
correctly support multiple devices to be passed through the VM and being
functional at the same time.

Add ability to notify via the GED device that there is some new hotplug
