The new virConnectGetSysinfo() API allows one to get the system
information associated to a connection host, providing the same
data as a guest that uses <os><smbios mode='host'/></os>, and in
a format that can be pasted into the guest and edited when using
<os><smbios mode='sysinfo'/></os>.

To enable virsh console (or equivalent) to be used remotely
it is necessary to provide remote access to the /dev/pts/XXX
pseudo-TTY associated with the console/serial/parallel device
in the guest. The virStream API provide a bi-directional I/O
stream capability that can be used for this purpose. This
patch thus introduces a virDomainOpenConsole API that uses
the stream APIs.

virDomainManagedSave() is to be run on a running domain. Once the call
complete, as in virDomainSave() the domain is stopped upon completion,
but there is no restore counterpart as any order to start the domain
from the API would load the state from the managed file, similary if
the domain is autostarted when libvirtd starts.
Once a domain has restarted his managed save image is destroyed,
basically managed save image can only exist for a stopped domain,
for a running domain that would be by definition outdated data.

This patch implements the core driver and provides
- management functionality for managing the filter XMLs
- compiling the internal filter representation into ebtables rules
- applying ebtables rules on a network (tap,macvtap) interface
- tearing down ebtables rules that were applied on behalf of an
interface
- updating of filters while VMs are running and causing the firewalls to
be rebuilt
- other bits and pieces

The current virDomainAttachDevice API can be (ab)used to change
the media of an existing CDROM/Floppy device. Going forward there
will be more devices that can be configured on the fly and overloading
virDomainAttachDevice for this is not too pleasant. This patch adds
a new virDomainUpdateDeviceFlags() explicitly just for modifying
existing devices.

The current API for domain events has a number of problems
- Only allows for domain lifecycle change events
- Does not allow the same callback to be registered multiple times
- Does not allow filtering of events to a specific domain
This introduces a new more general purpose domain events API
typedef enum {
VIR_DOMAIN_EVENT_ID_LIFECYCLE = 0, /* virConnectDomainEventCallback */
...more events later..
}
int virConnectDomainEventRegisterAny(virConnectPtr conn,
virDomainPtr dom, /* Optional, to filter */
int eventID,
virConnectDomainEventGenericCallback cb,
void *opaque,
virFreeCallback freecb);
int virConnectDomainEventDeregisterAny(virConnectPtr conn,
int callbackID);
Since different event types can received different data in the callback,
the API is defined with a generic callback. Specific events will each
have a custom signature for their callback. Thus when registering an
event it is neccessary to cast the callback to the generic signature
eg
int myDomainEventCallback(virConnectPtr conn,
virDomainPtr dom,
int event,
int detail,
void *opaque)
{
...
}
virConnectDomainEventRegisterAny(conn, NULL,
VIR_DOMAIN_EVENT_ID_LIFECYCLE,
VIR_DOMAIN_EVENT_CALLBACK(myDomainEventCallback)
NULL, NULL);
The VIR_DOMAIN_EVENT_CALLBACK() macro simply does a "bad" cast
to the generic signature
* include/libvirt/libvirt.h.in: Define new APIs for registering
domain events

There is currently no way to determine the libvirt version of a remote
libvirtd we are connected to. This is a useful piece of data to enable
feature detection.
Introduce a number of new APIs to expose some boolean properties
of objects, which cannot otherwise reliably determined, nor are
aspects of the XML configuration.
* virDomainIsActive: Checking virDomainGetID is not reliable
since it is not possible to distinguish between error condition
and inactive domain for ID of -1.
* virDomainIsPersistent: Check whether a persistent config exists
for the domain
* virNetworkIsActive: Check whether the network is active
* virNetworkIsPersistent: Check whether a persistent config exists
for the network
* virStoragePoolIsActive: Check whether the storage pool is active
* virStoragePoolIsPersistent: Check whether a persistent config exists
for the storage pool
* virInterfaceIsActive: Check whether the host interface is active
* virConnectIsSecure: whether the communication channel to the
hypervisor is secure
* virConnectIsEncrypted: whether any network based commnunication
channels are encrypted
NB, a channel can be secure, even if not encrypted, eg if it does
not involve the network, like a UNIX socket, or pipe.

Introduces several new public API options for migration
- VIR_MIGRATE_PEER2PEER: With this flag the client only
invokes the virDomainMigratePerform method, expecting
the source host driver to do whatever is required to
complete the entire migration process.
- VIR_MIGRATE_TUNNELLED: With this flag the actual data
for migration will be tunnelled over the libvirtd RPC
channel. This requires that VIR_MIGRATE_PEER2PEER is
also set.
- virDomainMigrateToURI: This is variant of the existing
virDomainMigrate method which does not require any
virConnectPtr for the destination host. Given suitable
driver support, this allows for all the same modes as
virDomainMigrate()
The URI for VIR_MIGRATE_PEER2PEER must be a valid libvirt
URI. For non-p2p migration a hypervisor specific migration
URI is used.
virDomainMigrateToURI without a PEER2PEER flag is only
support for Xen currently, and it involves XenD talking
directly to XenD, no libvirtd involved at all.
