On 64-bit platforms, unsigned long and unsigned long long are
identical, so we don't have to worry about overflow checks.
On 32-bit platforms, anywhere we narrow unsigned long long back
to unsigned long, we have to worry about overflow; it's easier
to do this in one place by having most of the code use the same
or wider types, and only doing the narrowing at the last minute.
Therefore, the memory set commands remain unsigned long, and
the memory get command now centralizes the overflow check into
libvirt.c, so that drivers don't have to repeat the work.
This also fixes a bug where xen returned the wrong value on
failure (most APIs return -1 on failure, but getMaxMemory
must return 0 on failure).

Function xmlParseURI does not remove square brackets around IPv6
address when parsing. One of the solutions is making wrappers around
functions working with xmlURI*. This assures that uri->server will be
always properly assigned and it doesn't have to be changed when used
on some new place in the code.
For this purpose, functions virParseURI and virSaveURI were
added. These function are wrappers around xmlParseURI and xmlSaveUri
respectively.
Also there is one new syntax check function to prohibit these functions
anywhere else.

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.

privP->session->error_description is a list and in order to get the
complete error message all parts of the list should be concatenated.
xenapiSessionErrorHandler does this when its third parameter is NULL.
The current code discards all but the first part of the error message
resulting in a potentially incomplete error message.
This partly reverts 006be75ee2, that tried to avoid reporting
a (null) in the error message. The actual problem is more general in
returnErrorFromSession that might return NULL if there is no error.
Make sure that returnErrorFromSession return non-NULL always. Also
don't skip the last error message part.
Coverity complained that most, but not all, clients of virUUIDParse

XenAPI session login can fail for a number of reasons, but currently no
specific
reason is displayed to the user, e.g.:
virsh -c XenAPI://citrix-xen.example.com/
Enter username for citrix-xen.example.com: root
Enter root's password for citrix-xen.example.com:
error: authentication failed: (null)
error: failed to connect to the hypervisor
This patch displays the session error description on failure.
Some drivers assumed it can be NULL (e.g. qemu and lxc) and check it
before assigning to it, other drivers assumed it must be non-NULL
(e.g. test and esx) and just assigned to it.
Unify this to nparams being optional and document it.
Change all the driver struct initializers to use the
C99 style, leaving out unused fields. This will make
it possible to add new APIs without changing every
driver. eg change:
qemudDomainResume, /* domainResume */
qemudDomainShutdown, /* domainShutdown */
NULL, /* domainReboot */
qemudDomainDestroy, /* domainDestroy */
to
.domainResume = qemudDomainResume,
.domainShutdown = qemudDomainShutdown,
.domainDestroy = qemudDomainDestroy,
And get rid of any existing C99 style initializersr which
set NULL, eg change
.listPools = vboxStorageListPools,
.numOfDefinedPools = NULL,
.listDefinedPools = NULL,
.findPoolSources = NULL,
.poolLookupByName = vboxStoragePoolLookupByName,
to
.listPools = vboxStorageListPools,
.poolLookupByName = vboxStoragePoolLookupByName,
Fix some driver names:

s/virDrvQemuDomainMonitorCommand/virDrvDomainQemuMonitorCommand/
s/virDrvSecretNumOfSecrets/virDrvNumOfSecrets/
s/virDrvSecretListSecrets/virDrvListSecrets/
And some driver struct field names:
s/getFreeMemory/nodeGetFreeMemory/
This matches the public API and helps to get rid of some special
case code in the remote generator.
Rename driver API functions and XDR protocol structs.
No functional change included outside of the remote generator.
We already have virAsprintf, so picking a similar name helps for
seeing a similar purpose. Furthermore, the prefix V before printf
generally implies 'va_list', even though this variant was '...', and
the old name got in the way of adding a new va_list version.
global rename performed with:
$ git grep -l virBufferVSprintf \
| xargs -L1 sed -i 's/virBufferVSprintf/virBufferAsprintf/g'
then revert the changes in ChangeLog-old.
Even with -Wuninitialized (which is part of autobuild.sh
--enable-compile-warnings=error), gcc does NOT catch this
use of an uninitialized variable:
{
if (cond)
goto error;
int a = 1;
error:
printf("%d", a);
}
which prints 0 (supposing the stack started life wiped) if
cond was true. Clang will catch it, but we don't use clang
as often. Using gcc -Wjump-misses-init catches it, but also
gives false positives:
{
if (cond)
goto error;
int a = 1;
return a;
error:
return 0;
}
Here, a was never used in the scope of the error block, so
declaring it after goto is technically fine (and clang agrees).
However, given that our HACKING already documents a preference
to C89 decl-before-statement, the false positive warning is
enough of a prod to comply with HACKING.
[Personally, I'd _really_ rather use C99 decl-after-statement
to minimize scope, but until gcc can efficiently and reliably
catch scoping and uninitialized usage bugs, I'll settle with
the compromise of enforcing a coding standard that happens to
reject false positives if it can also detect real bugs.]

xen-unstable c/s 16931 introduced a per-domain setting for hvm
guests to enable/disable hardware assisted paging. If disabled,
software techniques such as shadow page tables are used. If enabled,
and the feature exists in underlying hardware, hardware support for
paging is used.
This provides implementation for mapping HAP setting to/from
domxml/native formats in xen drivers.
Except LXC and UML driver, implementations of all other drivers
simply return 0, because these drivers doesn't have config both
in memory and on disk, no need to track if the domain of these
drivers updated or not.

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.

Although this patch adds a distinction between maximum vcpus and

a distinction be made.

Note - this wrapping is completely mechanical; the old API will
function identically, since the new API validates that the exact
same flags are provided by the old API. On a per-driver basis,
it may make sense to have the old API pass a different set of flags,

error: internal error unknown lifecycle type coredump-restart
This patch adds a new virDomainLifecycleCrash enum and appends
the new options to existing destroy, restart, preserve, and
rename-restart options.
Add the library entry point for the new virDomainQemuMonitorCommand()
entry point. Because this is not part of the "normal" libvirt API,
it gets its own header file, library file, and will eventually
get its own over-the-wire protocol later in the series.
Changes since v1:
- Go back to using the virDriver table for qemuDomainMonitorCommand, due to
linking issues
- Added versioning information to the libvirt-qemu.so
Changes since v2:
- None
Changes since v3:
- Add LGPL header to libvirt-qemu.c
- Make virLibConnError and virLibDomainError macros instead of function calls
Changes since v4:
- Move exported symbols to libvirt_qemu.syms

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
