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.
When the session has expired then multiple threads can race while
reestablishing it.
This race condition is not that critical as it requires a special usage
pattern to be triggered. It can only happen when an application doesn't
do API calls for quite some time (the session expires after 30 min
inactivity) and then multiple threads doing simultaneous API calls and
end up doing simultaneous calls to esxVI_EnsureSession.
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/virDrvSecretListSecrets/virDrvListSecrets/
And some driver struct field names:

Several vSphere API methods are called on global objects like the
FileManager, the PerformanceManager or the SearchIndex. The generator
input file allows to mark such methods and the generator generates
such method in a way that automatically handles marked parameter. This
is done by some special macros. Those were manually written and this
patch moves them to the generator.
These VIR_XXXX0 APIs make us confused, use the non-0-suffix APIs instead.
How do these coversions works? The magic is using the gcc extension of ##.
When __VA_ARGS__ is empty, "##" will swallow the "," in "fmt," to
avoid compile error.
example: origin after CPP
high_level_api("%d", a_int) low_level_api("%d", a_int)
high_level_api("a string") low_level_api("a string")
About 400 conversions.

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.
Add missing early exits and convert error logging to proper API level
error reporting.
Centralize cleanup code for the PerfQuerySpec object.
Reported by Eric Blake, detected by clang.
The ++ on preliminaryFileName was a left over from a previous version
of this function that explicitly returned the filename and did a strdup
on preliminaryFileName afterwards.
As the filename isn't returned explicitly anymore remove the preliminary
variable for it and reuse the tmp variable instead.

This was broken by the refactoring in ac1e6586ec. It resulted in a
segfault for 'virsh vol-dumpxml' and related volume functions.
Before the refactoring all users of the ESX_VI__TEMPLATE__DISPATCH
macro dispatched on the item type, as the item is the input to all those
functions.
Commit ac1e6586ec made the dynamically dispatched CastFromAnyType
functions use this macro too, but this functions dispatched on the
actual type of the AnyType object. The item is the output of the
CastFromAnyType functions.
This difference was missed in the refactoring, making CastFromAnyType
functions dereferencing the item pointer that is NULL at the time of
the dispatch.
This warnings come from partly generated code. Therefore, the best
solution is to mark them as potentially being unused using the
ATTRIBUTE_UNUSED macro. This is suggested by the gcc documentation.

Etienne Gosset reported that libvirt fails to connect to his ESX
server because it failed to parse its malformed host UUID, that
contains an additional space and lacks one hexdigit in the last
group:
xxxxxxxx-xxxx-xxxx-xxxx- xxxxxxxxxxx
Don't treat this as a fatal error, just ignore it.
Use it in all places where a memory or storage request size is converted
to a larger granularity. This avoids requesting too small memory or storage
sizes that could result from the truncation done by a simple division.
This extends the round up fix in 6002e0406c
to the whole codebase.
Instead of reporting errors for odd values in the VMX code round them up.
Update the QEMU Argv tests accordingly as the original memory size 219200
isn't a even multiple of 1024 and is rounded up to 215 megabyte now. Change
it to 219100 and 219136. Use two different values intentionally to make
sure that rounding up works.
Update virsh.pod accordingly, as rounding down and rejecting are replaced
by rounding up.
Now the VMware driver doesn't depend on the ESX driver anymore.

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
current vcpus in the XML, the values should be identical for all

a distinction be made.
In general, virDomainGetInfo should prefer the current vcpus.

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,

interface structure.
Since version 4.1 ESX(i) can expose virtual serial devices over TCP.
Add support in the VMX handling code for this, add test cases to cover
it and add links to some documentation.
ESX supports two additional protocols: TELNETS and TLS. Add them to
the list of serial-over-TCP protocols.
Before this commit SessionIsActive was not used because ESX(i)
doesn't implement it. vCenter supports SessionIsActive, so use
it here, but keep the fall back mechanism for ESX(i) and GSX.
QueryVirtualDiskUuid is only available on an ESX(i) server. vCenter
returns an NotImplemented fault and a GSX server is missing the
VirtualDiskManager completely. Therefore only use QueryVirtualDiskUuid
with an ESX(i) server and fall back to path as storage volume key for
vCenter and GSX server.
VirtualDisks are .vmdk file based. Other files in a datastore
like .iso or .flp files don't have a UUID attached, fall back
to the path as key for them.
Instead of splitting the path part of a datastore path into
directory and file name, keep this in one piece. An example:
"[datastore] directory/file"
was split into this before:
datastoreName = "datastore"
directoryName = "directory"
fileName = "file"
Now it's split into this:
datastoreName = "datastore"
directoryName = "directory"
directoryAndFileName = "directory/file"
This simplifies code using esxUtil_ParseDatastorePath, because
directoryAndFileName is used more often than fileName. Also the
old approach expected the datastore path to reference an actual
file, but this isn't always correct, especially when listing
volumes. In that case esxUtil_ParseDatastorePath is used to parse
a path that references a directory. This fails for a vpx://
connection because the vCenter returns directory paths with a
trailing '/'. The new approach is robust against this and the
actual decision if the datastore path should reference a file or
a directory is up to the caller of esxUtil_ParseDatastorePath.
Update the tests accordingly.
The check was altered in 8c48743b97
and got too strict, I've no clue how that snuck in. This check
makes every try to open a connection using the ESX driver fail
with an invalid argument error.
Revert the change to the check and add a comment to prevent future
mistakes with this check.
Instead of using one big traversal spec for lookup use a set of
more fine grained traversal specs that are selected based on the
actual needs of the lookup.
This gives up to 20% speedup for certain operations like domain
listing due to less HTTP(S) traffic.
With the previous storage pool UUID source not all storage pools
had a proper UUID, especially GSX storage pools. The mount path
is unique per host and cannot change during the lifetime of the
datastore. Therefore, it's MD5 sum can be used as UUID.
Use gnulib's crypto/md5 module to generate the MD5 sum.
In case an optional object cannot be found the lookup function is
left early and the cleanup code is not executed.
This pattern occurs in some other functions too.
floppy0.present defaults to true. Therefore, it needs to be
explicitly set to false when the XML config doesn't specify the
corresponding floppy device.
Also update tests accordingly.
For parsing try to match by datastore mount path first, if that
fails fallback to /vmfs/volumes/<datastore>/<path> parsing. This
also fixes problems with GSX on Windows. Because GSX on Windows
doesn't use /vmfs/volumes/ style file names.
For formatting use the datastore mount path too, instead of using
/vmfs/volumes/<datastore>/<path> as fixed format.
Introduce esxVMX_Context containing functions pointers to
glue both parts together in a generic way.
Move the ESX specific part to esx_driver.c.
This is a step towards making the VMX code reusable in a
potential VMware Workstation and VMware Player driver.
Don't rely on summary.url anymore, because its value is different
between an esx:// and vpx:// connection. Use host.mountInfo.path
instead.
Don't fallback to lookup by UUID (actually lookup by absolute path)
in esxVI_LookupDatastoreByName when lookup by name fails. Add a
seperate function for this: esxVI_LookupDatastoreByAbsolutePath
Now a vpx:// connection has an explicitly specified host. This
allows to enabled several functions for a vpx:// connection
again, like host UUID, hostname, general node info, max vCPU
count, free memory, migration and defining new domains.
Lookup datacenter, compute resource, resource pool and host
system once and cache them. This simplifies the rest of the
code and reduces overall HTTP(S) traffic a bit.
esx:// and vpx:// can be mixed freely for a migration.
Ensure that migration source and destination refer to the
same vCenter. Also directly encode the resource pool and
host system object IDs into the migration URI in the prepare
function. Then directly build managed object references in
the perform function instead of re-looking up already known
information.
