Currently the disk and chardev seclabels are validated immediately at
the time their data is parsed. This forces the parser to fill in the
top level secmodel at time of parsing which is an undesirable thing.
This validation conceptually should be done in the post-parse phase
instead.

Instead of using the virCapsPtr information, pass the driver specific
netprefix in the domain parser struct. This eliminates one more use of

To enable the virCapsPtr parameter to the post parse method to be
eliminated, the drivers must fetch the virCapsPtr from their own

The XML parser currently calls virCapabilitiesDomainDataLookup during
parsing to find the domain capabilities matching the triple
(virt type, os type, arch)
This is, however, bogus with the QEMU driver as it assumes that there
is an emulator known to the default driver capabilities that matches
this triple. It is entirely possible for the driver to be parsing an
XML file with a custom emulator path specified pointing to a binary
that doesn't exist in the default driver capabilities. This will,
for example be the case on a RHEL host which only installs the host
native emulator to /usr/bin. The user can have built a custom QEMU
for non-native arches into $HOME and wish to use that.
Aside from validation, this call is also used to fill in a machine type
for the guest if not otherwise specified. Again, this data may be
incorrect for the QEMU driver because it is not taking account of
the emulator binary that is referenced.
To start fixing this, move the validation to the post-parse callbacks
where more intelligent driver specific logic can be applied.

When parsing the guest XML we must fill in the default guest arch if it
is not already present because later parts of the parsing process need
this information.
If no arch is specified we lookup the first guest in the capabilities
data matching the os type and virt type. In most cases this will result
in picking the host architecture but there are some exceptions...
- The test driver is hardcoded to always use i686 arch
- The VMWare/ESX drivers will always place i686 guests ahead
of x86_64 guests in capabilities, so effectively they always
use i686
- The QEMU driver can potentially return any arch at all
depending on what combination of QEMU binaries are installed.
The domain XML hardware configurations are inherently architecture
specific in many places. As a result whomever/whatever created the
domain XML will have had a particular architecture in mind when
specifying the config. In pretty much any sensible case this arch
will have been the native host architecture. i686 on x86_64 is
the only sensible divergance because both these archs are
compatible from a domaain XML config POV.
IOW, although the QEMU driver can pick an almost arbitrary arch as its
default, in the real world no application or user is likely to be
relying on this default arch being anything other than native.
With all this in mind, it is reasonable to change the XML parser to
allow the default architecture to be passed via the domain XML options
struct. If no info is explicitly given then it is safe & sane to pick
the host native architecture as the default for the guest.
