b9f9f01fcc vmm: Extend seccomp filters to allow snapshot/restore
A few KVM ioctls were missing in order to perform both snapshot and
restore while keeping seccomp enabled.

2cd0bc0a2c vmm: Create initial VM from its snapshot
The MemoryManager is somehow a special case, as its restore() function
was not implemented as part of the Snapshottable trait. Instead, and
because restoring memory regions rely both on vm.json and every memory
region snapshot file, the memory manager is restored at creation time.
This makes the restore path slightly different from CpuManager, Vcpu,
DeviceManager and Vm, but achieve the correct restoration of the
MemoryManager along with its memory regions filled with the correct
content.

b55b83c6e8 vmm: vm: Implement the Transportable trait
This is only implementing the send() function in order to store all Vm
states into a file.

This needs to be extended for live migration, by adding more transport
methods, and also the recv() function must be implemented.

1ed357cf34 vmm: vm: Implement the Snapshottable trait
By aggregating snapshots from the CpuManager, the MemoryManager and the
DeviceManager, Vm implements the snapshot() function from the
Snapshottable trait.
And by restoring snapshots from the CpuManager, the MemoryManager and
the DeviceManager, Vm implements the restore() function from the
Snapshottable trait.

20ba271b6c vmm: memory_manager: Implement the Transportable trait
This implements the send() function of the Transportable trait, so that
the guest memory regions can be saved into one file per region.

This will need to be extended for live migration, as it will require
other transport methods and the recv() function will need to be
implemented too.

50b3f008d1 vmm: cpu: Implement the Snapshottable trait
Implement the Snapshottable trait for Vcpu, and then implements it for
CpuManager. Note that CpuManager goes through the Snapshottable
implementation of Vcpu for every vCPU in order to implement the
Snapshottable trait for itself.

f787c409c4 vmm: cpu: Factorize vcpu starting code
