This requires a custom function for remoteNodeDeviceDetachFlags,
because it is named *NodeDevice, but it goes through the hypervisor
driver rather than nodedevice driver, and so it uses privateData
instead of nodeDevicePrivateData. (It has to go through the hypervisor
driver, because that is the driver that knows about the backend drivers
that will perform the pci device assignment).
A number of the remote procedure names did not match the
corresponding API names. For example, many lacked the
word 'CONNECT', others re-arranged the names. Update the
procedures so their names exactly match the API names.
Then remove the special case handling of these APIs in
the generator

Like virNodeDeviceCreateXML, virNodeDeviceLookupSCSIHostByWWN
has to be treated specially when generating the RPC codes. Also
new rules are added in fixup_name to keep the name SCSIHostByWWN.
This patch adds a new API, virDomainOpenChannel, that uses streams to
connect to a virtio channel on a guest. This creates a secure
communication channel between a guest and a libvirt client.
This behaves the same as virDomainOpenConsole, except on channels
instead of console/serial/parallel devices.

It turns out that calling virNodeGetCPUMap(conn, NULL, NULL, 0)
is both useful, and with Viktor's patches, common enough to
optimize. Since this interface hasn't been released yet, we
can change the RPC call.
A bit more background on the optimization - learning the cpu count
is a single file read (/sys/devices/system/cpu/possible), but
learning the number of online cpus can possibly trigger a file
read per cpu, depending on the age of the kernel, and all wasted
if the caller passed NULL for both arguments.

This patch adds support for SUSPEND_DISK event; both lifecycle and
separated. The support is added for QEMU, machines are changed to
PMSUSPENDED, but as QEMU sends SHUTDOWN afterwards, the state changes
to shut-off. This and much more needs to be done in order for libvirt
to work with transient devices, wake-ups etc. This patch is not
aiming for that functionality.

This patch introduces a new event type for the QMP event
DEVICE_TRAY_MOVED, which occurs when the tray of a removable

VIR_DOMAIN_EVENT_ID_TRAY_CHANGE
The event's data includes the device alias and the reason
for tray status' changing, which indicates why the tray
status was changed. Thus the callback definition for the event
is:
enum {
VIR_DOMAIN_EVENT_TRAY_CHANGE_OPEN = 0,
VIR_DOMAIN_EVENT_TRAY_CHANGE_CLOSE,
\#ifdef VIR_ENUM_SENTINELS
VIR_DOMAIN_EVENT_TRAY_CHANGE_LAST

Our existing virDomainBlockResize takes an unsigned long long
argument; if that command is later taught a DELTA and SHRINK flag,
we cannot change its type without breaking API (but at least such
a change would be ABI compatible). Meanwhile, the only time a
negative size makes sense is if both DELTA and SHRINK are used
together, but if we keep the argument unsigned, applications can
pass the positive delta amount by which they would like to shrink
the system, and have the flags imply the negative value. So,
since this API has not yet been released, and in the interest of
consistency with existing API, we swap virStorageVolResize to
always pass an unsigned value.

This API allows a domain to be put into one of S# ACPI states.
Currently, S3 and S4 are supported. These states are shared
with virNodeSuspendForDuration.
However, for now we don't support any duration other than zero.
The same apply for flags.
Currently, we support only filling a volume with zeroes on wiping.
However, it is not enough as data might still be readable by
experienced and equipped attacker. Many technical papers have been
written, therefore we should support other wiping algorithms.
Add a new API virDomainShutdownFlags and define:
VIR_DOMAIN_SHUTDOWN_DEFAULT = 0,
VIR_DOMAIN_SHUTDOWN_ACPI_POWER_BTN = (1 << 0),
VIR_DOMAIN_SHUTDOWN_GUEST_AGENT = (1 << 1),
Also define some flags for the reboot API
VIR_DOMAIN_REBOOT_DEFAULT = 0,
VIR_DOMAIN_REBOOT_ACPI_POWER_BTN = (1 << 0),
VIR_DOMAIN_REBOOT_GUEST_AGENT = (1 << 1),
Although these two APIs currently have the same flags, using
separate enums allows them to expand separately in the future.

If a disk source gets dropped because it is not accessible,
mgmt application might want to be informed about this. Therefore
we need to emit an event. The event presented in this patch
is however a bit superset of what written above. The reason is simple:
an intention to be easily expanded, e.g. on 'user ejected disk
in guest' events. Therefore, callback gets source string and disk alias
(which should be unique among a domain) and reason (an integer);
Very mechanical. I'm so glad we've automated the generation of things,

This introduces a new domain
VIR_DOMAIN_EVENT_ID_CONTROL_ERROR
Which uses the existing generic callback
typedef void (*virConnectDomainEventGenericCallback)(virConnectPtr conn,
virDomainPtr dom,
void *opaque);
This event is intended to be emitted when there is a failure in
some part of the domain virtualization system. Whether the domain
continues to run/exist after the failure is an implementation
detail specific to the hypervisor.
The idea is that with some types of failure, hypervisors may
prefer to leave the domain running in a "degraded" mode of
operation. For example, if something goes wrong with the QEMU
monitor, it is possible to leave the guest OS running quite
happily. The mgmt app will simply loose the ability todo various
tasks. The mgmt app can then choose how/when to deal with the
failure that occured.

Apparently introdunced in commit 376e1d9420
the generator produces u_int flags not unsigned int flags.
* src/remote_protocol-structs: fix to the actual expected type and
alignment
In most cases this affects flags parameters that are unsigned in the
public and driver API but signed in the XDR protocol. Switch the
XDR protocol to unsigned for those.
A counterexample is virNWFilterGetXMLDesc. Its flags parameter is signed
in the public API and XDR protocol, but unsigned in the driver API.
virNodeGetFreeMemory used unsigned long long in the public API but
signed hyper in the XDR protocol. Convert the XDR protocol to use
unsigned hyper.
As explained by Eric before, this doesn't affect the on-the-wire protocol.
The current virDomainMigrateFinish3 method signature attempts to
distinguish two types of errors, by allowing return with ret== 0,
but ddomain == NULL, to indicate a failure to start the guest.
This is flawed, because when ret == 0, there is no way for the
virErrorPtr details to be sent back to the client.
Change the signature of virDomainMigrateFinish3 so it simply
returns a virDomainPtr, in the same way as virDomainMigrateFinish2
The disk locking code will protect against the only possible
failure mode this doesn't account for (loosing conenctivity to
libvirtd after Finish3 starts the CPUs, but before the client
sees the reply for Finish3).
* src/driver.h, src/libvirt.c, src/libvirt_internal.h: Change
virDomainMigrateFinish3 to return a virDomainPtr instead of int
* src/remote/remote_driver.c, src/remote/remote_protocol.x,
daemon/remote.c, src/qemu/qemu_driver.c, src/qemu/qemu_migration.c:
Update for API change
The virDomainMigratePerform3 currently has a single URI parameter
whose meaning varies. It is either
- A QEMU migration URI (normal migration)
- A libvirtd connection URI (peer2peer migration)
Unfortunately when using peer2peer migration, without also
using tunnelled migration, it is possible that both URIs are
required.
This adds a second URI parameter to the virDomainMigratePerform3
method, to cope with this scenario. Each parameter how has a fixed
meaning.
NB, there is no way to actually take advantage of this yet,
since virDomainMigrate/virDomainMigrateToURI do not have any
way to provide the 2 separate URIs
* daemon/remote.c, src/remote/remote_driver.c,
src/remote/remote_protocol.x, src/remote_protocol-structs: Add
the second URI parameter to perform3 message
* src/driver.h, src/libvirt.c, src/libvirt_internal.h: Add
the second URI parameter to Perform3 method
* src/libvirt_internal.h, src/qemu/qemu_migration.c,
src/qemu/qemu_migration.h: Update to handle URIs correctly
This extends the v3 migration protocol such that the
virDomainMigrateBegin3 and virDomainMigratePerform3
methods accept an application supplied XML config for
the target VM.
If the 'xmlin' parameter is NULL, then Begin3 uses the
current guest XML as normal. A driver implementing the
Begin3 method should either reject all non-NULL 'xmlin'
parameters, or strictly validate that the app supplied
XML does not change guest ABI.
The Perform3 method also needed the xmlin parameter to
cope with the Peer2Peer migration sequence.
NB it is not yet possible to use this capability since
neither of the public virDomainMigrate/virDomainMigrateToURI
methods have a way to pass in XML.
* daemon/remote.c, src/remote/remote_driver.c,
src/remote/remote_protocol.x, src/remote_protocol-structs:

Update remote_protocol-structs to placate make syntax-check.
Undo unintended modifications in vboxDomainGetInfo.
Update the function table of the VirtualBox and XenAPI drivers.
Define the wire format for the new virDomainCreateWithFlags
API, and implement client and server side of marshaling code.
* daemon/remote.c (remoteDispatchDomainCreateWithFlags): Add
server side dispatch for virDomainCreateWithFlags.
* src/remote/remote_driver.c (remoteDomainCreateWithFlags)
(remote_driver): Client side serialization.
* src/remote/remote_protocol.x
(remote_domain_create_with_flags_args)
(remote_domain_create_with_flags_ret)
(REMOTE_PROC_DOMAIN_CREATE_WITH_FLAGS): Define wire format.
* daemon/remote_dispatch_args.h: Regenerate.
* daemon/remote_dispatch_prototypes.h: Likewise.
* daemon/remote_dispatch_table.h: Likewise.
* src/remote/remote_protocol.c: Likewise.
* src/remote/remote_protocol.h: Likewise.
* src/remote_protocol-structs: Likewise.
Now, if you update remote_protocol.x without also updating
remote_protocol-structs to match, then "make check" will fail.
* src/Makefile.am (remote_protocol-structs): Extract list of
structs and member names from remote_protocol.o.
(check-local): Depend on it.
* src/remote_protocol-structs: New file.
