02411a4597 docstring: Fix generated documentation of virStorageVolInfoFlags
The API xml description file generator doesn't properly handle cases
when there's either a single comment or mixed use of pre- and post-
comments explaining the values.

Modify the comments to avoid the problem and also append version

89f35b1214 docstring: variable: Move docstring from source to header file
virConnectAuthPtrDefault is the only variable that we export and
with the documentation being at the C file, it makes harder to find
it.

With this patch, the documentation of this variable can be found by
those who look at the header file for guidance plus, it will also be
included in the XML API, as the followup patch will fix apibuild.py
to store what is documented in the header file for this variable.

Note that the apibuild, does not do the same with .c files. It'd
require adding it for (parsing) recursion, similar to what is done
for functions.  Considering the pros/cons, seems more reasonable to
move the docstring to the header file instead.

c08dad9ae2 docstring: Fix generated documentation of virConnectListAllNodeDeviceFlags
scripts/apibuild.py does not handle well enum's with comments
between values.  The outcome depends on whether the enum value has
its own docstring or not and if there is spaces between the enum

Either way, virConnectListAllNodeDeviceFlags documentation is
explicit that this enum is about filtering node devices. We can move
the information that it is either by "capability" or "active" state
to the block of comment above.

12a658ecf7 include: define constants for resetting NVRAM state
When starting a guest with pflash based firmware, we will initialize
NVRAM from a template if it does not already exist. In theory if the
firmware code file is updated, the existing NVRAM variables should
continue to work correctly. It is inevitable that this could break
accidentally one day. Or a bug in the firmware might corrupt the
NVRAM storage. Or user might make bad changes to the settings that
prevent booting. Or the user might have re-configured the XML to
point to a different firmware file incompatible with the current
variables.

In all these cases it would be useful to delete the existing NVRAM
and initialize it from the pristine template.

To support this introduce a VIR_DOMAIN_START_RESET_NVRAM constant
for use with virDomainCreate / virDomainCreateXML, along with
VIR_DOMAIN_SAVE_RESET_NVRAM for use with virDomainRestore and
VIR_DOMAIN_SNAPSHOT_REVERT_RESET_NVRAM for use with
virDomainSnapshotRevert.

d46142a2f9 libvirt: Introduce virDomainSetLaunchSecurityState public API
This API allows setting a launch secret within a guests's memory. The
launch secret is created by the guest owner after retrieving and
verifying the launch measurement with virDomainGetLaunchSecurityInfo.

The API uses virTypedParameter for input, allowing it to be expanded
to support other confidential computing technologies. In the case of
SEV, a basic guest launch workflow is described in the SEV API spec
in section "1.3.1 Launch"

51d1c08fe9 virDomainMigrate: Introduce VIR_MIGRATE_NON_SHARED_SYNCHRONOUS_WRITES flag
Non-shared storage migration of guests which are disk I/O intensive and
have fast local storage may actually never converge if the guest happens
to dirty the disk faster than it can be copied.

This patch introduces a new flag
'VIR_MIGRATE_NON_SHARED_SYNCHRONOUS_WRITES' which will instruct
hypervisors to synchronize local I/O writes with the writes to remote
storage used for migration so that the guest can't overwhelm the
migration. This comes at a cost of decreased local I/O performance for
guests which behave well on average.

9985f62b51 qemu: Wire up MEMORY_DEVICE_SIZE_CHANGE event
As advertised in previous commit, this event is delivered to us
when virtio-mem module changes the allocation inside the guest.
It comes with one attribute - size - which holds the new size of
the virtio-mem (well, allocated size), in bytes.
Mind you, this is not necessarily the same number as 'requested
size'. It almost certainly will be when sizing the memory up, but
it might not be when sizing the memory down - the guest kernel
might be unable to free some blocks.

This current size is reported in the domain XML as an output
element only.

56fbabf1a1 Add basic driver for the Cloud-Hypervisor
Cloud-Hypervisor is a KVM virtualization using hypervisor. It
functions similarly to qemu and the libvirt Cloud-Hypervisor driver
uses a very similar structure to the libvirt driver.

The biggest difference from the libvirt perspective is that the
"monitor" socket is seperated into two sockets one that commands are
issued to and one that events are notified from. The current
implementation only uses the command socket (running over a REST API
with json encoded data) with future changes to add support for the
event socket (to better handle shutdowns from inside the VM).

This patch adds support for the following initial VM actions using the
Cloud-Hypervsior API:
 * vm.create
 * vm.delete
 * vm.boot
 * vm.shutdown
 * vm.reboot
 * vm.pause
 * vm.resume

To use the Cloud-Hypervisor driver, the v15.0 release of
Cloud-Hypervisor is required to be installed.

Some additional notes:
 * The curl handle is persistent but not useful to detect ch process
 shutdown/crash (a future patch will address this shortcoming)
 * On a 64-bit host Cloud-Hypervisor needs to support PVH and so can
 emulate 32-bit mode but it isn't fully tested (a 64-bit kernel and
 32-bit userspace is fine, a 32-bit kernel isn't validated)

already checks supported formats via

'dump-guest-memory'.
