While checking for ABI stability, drivers might pose additional
checks that are not valid for general case. For instance, qemu
driver might check some memory backing attributes because of how
qemu works. But those attributes may work well in other drivers.

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.
The virDomainDefParse* and virDomainDefFormat* methods both
accept the VIR_DOMAIN_XML_* flags defined in the public API,
along with a set of other VIR_DOMAIN_XML_INTERNAL_* flags
defined in domain_conf.c.
This is seriously confusing & error prone for a number of
reasons:
- VIR_DOMAIN_XML_SECURE, VIR_DOMAIN_XML_MIGRATABLE and
VIR_DOMAIN_XML_UPDATE_CPU are only relevant for the
formatting operation
- Some of the VIR_DOMAIN_XML_INTERNAL_* flags only apply
to parse or to format, but not both.
This patch cleanly separates out the flags. There are two
distint VIR_DOMAIN_DEF_PARSE_* and VIR_DOMAIN_DEF_FORMAT_*
flags that are used by the corresponding methods. The
VIR_DOMAIN_XML_* flags received via public API calls must
be converted to the VIR_DOMAIN_DEF_FORMAT_* flags where
needed.
The various calls to virDomainDefParse which hardcoded the
use of the VIR_DOMAIN_XML_INACTIVE flag change to use the
VIR_DOMAIN_DEF_PARSE_INACTIVE flag.

Adds test for transient disk translation in vmx files
Any test suite which involves a virDomainDefPtr should
call virDomainDefCheckABIStability with itself just as
a basic sanity check that the identity-comparison always
succeeds. This would have caught the recent NULL pointer
access crash.
Make sure we cope with def->name being NULL since the
VMWare config parser produces NULL names.

A user was having an issue with this specific VMWare Fusion config and
he gave me permission to add it as part of our test suite to further
expand our VMX test coverage. Unfortunately our VMX parser and
generator does not support many features contained within and just
silently ignores fields it does not understand so they had to
be removed out in the xml2vmx test. The original unmodified version
exists in the vmx2xml test.
VMWare Fusion 5 can set the CD-ROM's device name to be 'auto detect' when
using the physical drive via 'cdrom-raw' device type. VMWare will then
connect to first available host CD-ROM to the virtual machine upon start
up according to VMWare documentation. If no device is available, it
appears that the device will remain disconnected.
To better model this a CD-ROM that is marked as "auto detect" when in
the off state would be modeled as the following with this patch:
<disk type='block' device='lun'>
<source startupPolicy='optional'/>
<target dev='hda' bus='ide'/>
<address type='drive' controller='0' bus='0' target='0' unit='0'/>
</disk>
Once the domain transitions to the powered on state, libvirt can
populate the remaining source data with what is connected, if anything.
However future power cycles, the domain may not always start with that
device attached.
According to VMWare's documentation 'cdrom-raw' is an acceptable value
for deviceType for a CD-ROM drive. The documentation states that the VMX
configuration for a CD-ROM deviceType is as follows:
ide|scsi(n):(n).deviceType = "cdrom-raw|atapi-cdrom|cdrom-image"
From the documentation it appears the following is true:
- cdrom-image = Provides the ISO to the VM
- atapi-cdrom = Provides a NEC emulated ATAPI CD-ROM on top of the host
CD-ROM
- cdrom-raw = Passthru for a host CD-ROM drive. Allows CD-R burning from
within the guest.
A CD-ROM prior to this patch would always provide an 'atapi-cdrom' is
modeled as:
<disk type='block' device='cdrom'>
<source dev='/dev/scd0'/>
<target dev='hda' bus='ide'/>
<address type='drive' controller='0' bus='0' target='0' unit='0'/>
</disk>
This patch allows the 'device' attribute to be set to 'lun' for a raw
acccess CD-ROM such as:
<disk type='block' device='lun'>
<source dev='/dev/scd0'/>
<target dev='hda' bus='ide'/>
<address type='drive' controller='0' bus='0' target='0' unit='0'/>
</disk>
The source code base needs to be adapted as well. Some files
include virutil.h just for the string related functions (here,
the include is substituted to match the new file), some include
virutil.h without any need (here, the include is removed), and
some require both.
This patch refactors various places to allow removing of the
defaultConsoleTargetType callback from the virCaps structure.
A new console character device target type is introduced -
VIR_DOMAIN_CHR_CONSOLE_TARGET_TYPE_NONE - to mark that no type was
specified in the XML. This type is at the end converted to the standard
VIR_DOMAIN_CHR_CONSOLE_TARGET_TYPE_SERIAL. Other types that are
different from this default have to be processed separately in the
device post parse callback.
Use the virDomainXMLConf structure to hold this data and tweak the code
to avoid semantic change.
Without configuration the KVM mac prefix is used by default. I chose it
as it's in the privately administered segment so it should be usable for
any purposes.
To enable virCapabilities instances to be reference counted,
turn it into a virObject. All cases of virCapabilitiesFree
turn into virObjectUnref

For S390, the default console target type cannot be of type 'serial'.
It is necessary to at least interpret the 'arch' attribute
value of the os/type element to produce the correct default type.
Therefore we need to extend the signature of defaultConsoleTargetType
to account for architecture. As a consequence all the drivers
supporting this capability function must be updated.
Despite the amount of changed files, the only change in behavior is
that for S390 the default console target type will be 'virtio'.
N.B.: A more future-proof approach could be to to use hypervisor
specific capabilities to determine the best possible console type.
For instance one could add an opaque private data pointer to the
virCaps structure (in case of QEMU to hold capsCache) which could
then be passed to the defaultConsoleTargetType callback to determine
the console target type.
Seems to be however a bit overengineered for the use case...

This patch adds support for vmx files with empty networkName
values (which is the case for vmx generated by Workstation).
It also adds support for vmx containing NATed network interfaces.
Update test suite accordingly
The default console type may vary based on the OS type. ie a Xen
paravirt guests wants a 'xen' console, while a fullvirt guests
wants a 'serial' console.
A plain integer default console type in the capabilities does
not suffice. Instead introduce a callback that is passed the
OS type.
* src/conf/capabilities.h: Use a callback for default console
type
* src/conf/domain_conf.c, src/conf/domain_conf.h: Use callback
for default console type. Add missing LXC/OpenVZ console types.
* src/esx/esx_driver.c, src/libxl/libxl_conf.c,
src/lxc/lxc_conf.c, src/openvz/openvz_conf.c,
src/phyp/phyp_driver.c, src/qemu/qemu_capabilities.c,
src/uml/uml_conf.c, src/vbox/vbox_tmpl.c,
src/vmware/vmware_conf.c, src/xen/xen_hypervisor.c,
src/xenapi/xenapi_driver.c: Set default console type callback
Before commit 145d6cb05c (in August 2010) absolute file names
in VMX and domain XML configs were handled correctly. But this got
lost during the refactoring. The test cases didn't highlight this
problem because they have their own set of file name handling
functions. The actual ones require a real connection to an ESX
server. Also the test case functions always worked correctly.
Fix the regression and add a new in-the-wild VMX file that contains
such a problematic absolute path. Even though this test case won't
protect against new regressions.

Make virtTestLoadFile allocate the buffer to read the file into.
Fix logic error in virtTestLoadFile, stop reading on the first empty line.
Use virFileReadLimFD in virtTestCaptureProgramOutput to avoid manual
buffer handling.
A few of the tests were missing basic sanity checks, while most
of them were doing copy-and-paste initialization (in fact, some
of them pasted the argc > 1 check more than once!). It's much
nicer to do things in one common place, and minimizes the size of
the next patch that fixes getcwd usage.

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.
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.
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.
