We need the project to rely on kvm-bindings and kvm-ioctls branches
which include the serde derive to be able to serialize and deserialize
some KVM structures.

The parse_size helper function can now be consolidated into the
ByteSized FromStr implementation.
Signed-off-by: Rob Bradford <robert.bradford@intel.com>
Now all parsing code makes use of the Toggle and it's FromStr support
move the helper function into the from_str() implementation.

The integration tests and documentation make use of empty value strings
like "--net tap=" accept them but return None so that the default value
will be used as expected.

This simplifies the parsing of the option by using OptionParser along
with its automatic conversion behaviour.
Signed-off-by: Rob Bradford <robert.bradford@intel.com>
Byte sizes are quantities ending in "K", "M", "G" and by implementing
this type with a FromStr implementation the values can be converted
using .parse().

Before porting over to OptionParser add a unit test to validate the
current memory parsing code. This showed up a bug where the "size=" was
always required. Temporarily resolve this by assigning the string a
default value which will later be replaced when the code is refactored.

This will be used to simplify and consolidate much of the parsing code
used for command line parameters.

A Snapshottable component can snapshot itself and
provide a MigrationSnapshot payload as a result.
A MigrationSnapshot payload is a map of component IDs to a list of
migration sections (MigrationSection). As component can be made of
several Migratable sub-components (e.g. the DeviceManager and its
device objects), a migration snapshot can be made of multiple snapshot
itself.
A snapshot is a list of migration sections, each section being a
component state snapshot. Having multiple sections allows for easier and
backward compatible migration payload extensions.
Once created, a migratable component snapshot may be transported and this
is what the Transportable trait defines, through 2 methods: send and recv.

On some systems, the open() system call is used by Cloud-Hypervisor,
that's why it should be part of the seccomp filters whitelist.
Signed-off-by: Sebastien Boeuf <sebastien.boeuf@intel.com>
Both clock_gettime and gettimeofday syscalls where missing when running
Cloud-Hypervisor on a Linux host without vDSO enabled. On a system with
vDSO enabled, the syscalls performed by vDSO were not filtered, that's
why we didn't have to whitelist them.

Extend the update_memory() method from DeviceManager so that VFIO PCI
devices can update their DMA mappings to the physical IOMMU, after a
memory hotplug has been performed.
