If you use the VDDK library to access virtual machines remotely, you
really need to know the Managed Object Reference ("moref") of the VM.
This must be passed each time you connect to the API.
For example nbdkit's VDDK plugin requires a moref to be passed to
mount up a VM's disk remotely:
nbdkit vddk user=root password=+/tmp/rootpw \
server=esxi.example.com thumbprint=xx:xx:xx:... \
vm=moref=2 \
file="[datastore1] Fedora/Fedora.vmdk"
Getting the moref is a huge pain. To get some idea of what it is, why
it is needed, and how much trouble it is to get it, see:
https://blogs.vmware.com/vsphere/2012/02/uniquely-identifying-virtual-machines-in-vsphere-and-vcloud-part-1-overview.htmlhttps://blogs.vmware.com/vsphere/2012/02/uniquely-identifying-virtual-machines-in-vsphere-and-vcloud-part-2-technical.html
However the moref is available conveniently in the internals of the
libvirt VMX driver. This patch exposes it as a custom XML element
using the same "vmware:" namespace which was previously used for the
datacenterpath (see libvirt commit 636a990587).
It appears in the XML like this:
<domain type='vmware' xmlns:vmware='http://libvirt.org/schemas/domain/vmware/1.0'>
<name>Fedora</name>
...
<vmware:datacenterpath>ha-datacenter</vmware:datacenterpath>
<vmware:moref>2</vmware:moref>
</domain>
Note that the moref can appear as either a simple ID (for esx://
connections) or as a "vm-<ID>" (for vpx:// connections). It should be
treated by users as an opaque string.

This change ensures to call driver specific post-parse code to modify
domain definition after parsing hypervisor config the same way we do
after parsing XML.

Tool such as libguestfs need the datacenter path to get access to disk
images. The ESX driver knows the correct datacenter path, but this
information cannot be accessed using libvirt API yet. Also, it cannot
be deduced from the connection URI in a robust way.
Expose the datacenter path in the domain XML as <vmware:datacenterpath>
node similar to the way the <qemu:commandline> node works. The new node
is ignored while parsing the domain XML. In contrast to <qemu:commandline>
it is output only.

When generating the default drive address for a SCSI <disk> device,
check the generated address to ensure it doesn't conflict with a SCSI
<hostdev> address. The <disk> address generation algorithm uses the
<target> "dev" name in order to determine which controller and unit
in order to place the device. Since a SCSI <hostdev> device doesn't
require a target device name, its placement on the guest SCSI address
"could" conflict. For instance, if a SCSI <hostdev> exists at
controller=0 unit=0 and an attempt to hotplug 'sda' into the guest
made, there would be a conflict if the <hostdev> is already using
/dev/sda.
If there should be some sort of separator it is better to use comment
with the filename, copyright, description, license information and
authors.

virVMXFormatHardDisk() and virVMXFormatCDROM() duplicated a lot of code
from each other and made a lot of nested if checks to build each part of
the VMX file. This hopefully simplifies the code path while combining
the two functions with no net difference.

This patch removes the explicit FSF address, and uses above instead
(of course, with inserting 'Lesser' before 'General').
Except a bunch of files for security driver, all others are changed
automatically, the copyright for securify files are not complete,
that's why to do it manually:
src/security/security_selinux.h
src/security/security_driver.h
src/security/security_selinux.c
src/security/security_apparmor.h
src/security/security_apparmor.c
src/security/security_driver.c
Now the VMware driver doesn't depend on the ESX driver anymore.
Add a WITH_VMX option that depends on WITH_ESX and WITH_VMWARE.
Also add a libvirt_vmx.syms file.
Move some escaping functions from esx_util.c to vmx.c.
Adapt the test suite, ESX and VMware driver to the new code layout.
