This patch series adds support for serial & parallel devices to

The following syntax is used. Anywhere you see 'serial', you can equally
use 'console' or 'parallel'.
The 'serial' is for real serial devices only, likewise 'parallel' is for
parallel port devices only. 'console' tag is for paravirtualized
consoles. IF there is no paravirt console, then the first serial device
(if any) is also duplicated as a 'console' tag. This provides backwards
compatability with existing syntax.
[...]
This is sufficient flexibility to represent all QEMU character device
modes,
Xen paravirt console, LXC container fake console and the Solaris LDoms
console, and VMWare serial devices.
This series of patches updates the Xen and QEMU drivers, and their test
suites. A later patch will also update the LXC driver to this new syntax.
Fine by me, let's push this, feedback may lead to a bit of tweaking of
the code but it will be easier to deal with as diff from CVS than on this
patchset.
I was going to document this all in the format.html page, but
looking at
the content there it needs a complete re-write. The split between Xen and
QEMU formats is pointless because they share 95% of the their config. Both
the Xen and QEMU descriptions are outdated, and the Xen PV vs HVM split is
also less than useful since they have much more commmonaility now. I intend
to re-write it to describe each element / attribute in turn, and then at
the end provide some example configs for each driver.
If we can achieve this then that means we should also be able to maintain
the relaxng schemas, ship it with the distribution and even pissibly add a
checking rule as part of virsh.
