An ESX server has one or more PhysicalNics that represent the actual
hardware NICs. Those can be listed via the interface driver.
A libvirt virtual network is mapped to a HostVirtualSwitch. On the
physical side a HostVirtualSwitch can be connected to PhysicalNics.
On the virtual side a HostVirtualSwitch has HostPortGroups that are
mapped to libvirt virtual network's portgroups. Typically there is
HostPortGroups named 'VM Network' that is used to connect virtual
machines to a HostVirtualSwitch. A second HostPortGroup typically
named 'Management Network' is used to connect the hypervisor itself
to the HostVirtualSwitch. This one is not mapped to a libvirt virtual
network's portgroup. There can be more HostPortGroups than those
typical two on a HostVirtualSwitch.

| HostPortGroup | |---| PhysicalNic |

...---| | | +-------------+
+---------------+ HostVirtualSwitch |
| vSwitch0 |
+---------------+ |
| HostPortGroup | |
...---| Management | |
| Network | |
+---------------+-------------------+
The virtual counterparts of the PhysicalNic is the HostVirtualNic for
the hypervisor and the VirtualEthernetCard for the virtual machines
that are grouped into HostPortGroups.

The currently implemented network driver can list, define and undefine
HostVirtualSwitches including HostPortGroups for virtual machines.
Existing HostVirtualSwitches cannot be edited yet. This will be added
in a followup patch.
esxVI_LookupHostSystemProperties guarantees that hostSystem is non-NULL.
Remove redundant NULL checks from callers.
Also prefer esxVI_GetStringValue over open-coding the logic.
The static deep copy allocates storage for the copy. The dynamic
version injected the dynamic dispatch after the allocation. This
triggered the invalid argument check in the dynamically dispatched
deep copy call. The deep copy function expects its dest parameter
to be a pointer to a NULL-pointer. This expectation wasn't met due
to the dispatching deep copy doing the allocation before the call.
Fix this by dynamically dispatching to the correct type before the
allocation.
Lists available PhysicalNic devices. A PhysicalNic is always active
and can neither be defined nor undefined.
A PhysicalNic is used to bridge a HostVirtualSwitch to the physical
network.

Update the ESX driver to use virReportError instead of
the ESX_ERROR & ESX_VI_ERROR custom macros

It was broken since forever as it expected a libxml2
XML_ELEMENT_NODE containing a XML_TEXT_NODE instead of
just a XML_TEXT_NODE.
This problem was not discovered for so long because
esxVI_String_Deserialize was not used until now.

The two new APIs are rather trivial; based on bits and pieces of
other existing APIs. But rather than blindly return 0 or 1 for
HasMetadata, I chose to first validate that the snapshot in
question in fact exists.
* src/esx/esx_driver.c (esxDomainSnapshotIsCurrent)
(esxDomainSnapshotHasMetadata): New functions.
* src/vbox/vbox_tmpl.c (vboxDomainSnapshotIsCurrent)
(vboxDomainSnapshotHasMetadata): Likewise.
Blindly returning success is misleading if the object no longer
exists; it is a bit better to check for existence up front before
returning information about that object. This pattern matches the
fact that most of our other APIs check for existence as a side
effect prior to getting at the real piece of information being
queried.
* src/esx/esx_driver.c (esxDomainIsUpdated, esxDomainIsPersistent):
Add existence checks.
* src/vbox/vbox_tmpl.c (vboxDomainIsPersistent)

Appending an item to a list transfers ownership of that item to the
list owner. But an error can occur in between item allocation and
appending it to the list. In this case the item has to be freed
explicitly. This was not done in some special cases resulting in
possible memory leaks.

The current storage pools for NFS and iSCSI only require one host to
connect to. Future storage pools like RBD and Sheepdog will require
multiple hosts.
This patch allows multiple source hosts and rewrites the current

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.
File changes:
- src/util/viruri.h -- declaration
- src/util/viruri.c -- definition
- src/libvirt_private.syms -- symbol export
- src/Makefile.am -- added source and header files
- cfg.mk -- added sc_prohibit_xmlURI
- all others -- ID name and include fixes
Adding "Expect:" to the header list stops libcurl from sending a
Expect header at all.
Before, a dummy Expect header was added that might confuse HTTP
proxies and result in HTTP error code 417 being reported.

Add a new API virDomainShutdownFlags and define:

Allow the datacenter and compute resource parts of the path
to be prefixed with folders. Therefore, the way the path is
parsed has changed. Before, it was split in 2 or 3 items and
the items' meanings were determined by their positions. Now
the path can have 2 or more items and the the vCenter server
is asked whether a folder, datacenter of compute resource
with the specified name exists at the current hierarchy level.
Before the datacenter and compute resource lookup automatically
traversed folders during lookup. This is logic got removed
and folders have to be specified explicitly.
The proper datacenter path including folders is now used when
accessing a datastore over HTTPS. This makes virsh dumpxml
and define work for datacenters in folders.
