The counters are a hash of device name to hash of counter name to u64
value. Currently the API is only implemented with a stub that returns an
empty set of counters.

Now that PCI device hotplug returns a response, the OpenAPI definition
must reflect it, describing what is expected to be received.

This patch completes the series by connecting the dots between the HTTP
frontend and the device manager backend.
Any request to hotplug a VFIO, disk, fs, pmem, net, or vsock device will
now return a response including the device name and the place of the
device in the PCI topology.

Instead of responding only headers with error code, we now return
complete error responses to HTTP requests with errors (e.g. undefined
endpoints and InternalSeverError).

Like the actions that don't take data such as "pause" or "resume" use a
common handler implementation to remove duplicated code for handling
simple endpoints like the hotplug ones.
Signed-off-by: Rob Bradford <robert.bradford@intel.com>
Many of the API requests take a similar form with a single data item
(i.e. config for a device hotplug) expand the VmAction enum to handle
those actions and a single function to dispatch those API events.
For now port the existing helper functions to use this new API. In the
future the HTTP layer can create the VmAction directly avoiding the
extra layer of indirection.
Signed-off-by: Rob Bradford <robert.bradford@intel.com>
Rather than save the save a function pointer and use that instead the
underlying action. This is useful for two reasons:
1. We can ensure that we generate HttpErrors in the same way as the
other endpoints where API error variant should be determined by the
request being made not the underlying error.
2. It can be extended to handle other generic actions where the function
prototype differs slightly.
As result of this refactoring it was found that the "vm.delete" endpoint
was not connected so address that issue.

If a size is specified use it (in particular this is required if the

of the file.
Add a new check that the size is a multiple of 2MiB otherwise the kernel

The new 'shared' and 'hugepages' controls aim to replace the 'file'
option in MemoryConfig. This patch also updated all related integration
tests to use the new controls (instead of providing explicit paths to
"/dev/shm" or "/dev/hugepages").

This opens the backing file read-only, makes the pages in the mmap()
read-only and also makes the KVM mapping read-only. The file is also
mapped with MAP_PRIVATE to make the changes local to this process only.
This is functional alternative to having support for making a
virtio-pmem device readonly. Unfortunately there is no concept of
readonly virtio-pmem (or any type of NVDIMM/PMEM) in the Linux kernel so
to be able to have a block device that is appears readonly in the guest
requires significant specification and kernel changes.

Add a new id option to the VFIO hotplug command so that it matches the
VFIO coldplug semantic.
This is done by refactoring the existing code for VFIO hotplug, where
VmAddDeviceData structure is replaced by DeviceConfig. This structure is
the one used whenever a VFIO device is coldplugged, which is why it
makes sense to reuse it for the hotplug codepath.
Signed-off-by: Sebastien Boeuf <sebastien.boeuf@intel.com>
Add the ability to specify the "id" associated with a device, by adding
an extra option to the parameter --device.
This new option is not mandatory, and by default, the VMM will take care
of finding a unique identifier.
If the identifier provided by the user through this new option is not
unique, an error will be thrown and the VM won't be started.
