With qemu it is possible to override the geometry (cylinders, heads,
sectors) of disks.
This series adds a new XML tag for geometry and the related
support in the qemu driver.
V2 Changes:
Refactor into the generic domain configuration/XML support for disk
geometry and a qemu specific part with the testcase
V3 Changes:
1. Use virReportError instead of custom xxxReportError.
2. Moved the geometry element to diskspec, so it applies to all kind
of disks.
V4 Changes:
Rebase for libvirt 0.10.0 freeze.
V5 Changes:
Corrected qemuxml2argvtest invocation. Oversight after rebase.
V6 Changes:
The geometry info was incorrectly processed only for block and file
based disks. Fixed.

New subject: [libvirt] [PATCHv6 1/2] Support for Disk Geometry Override
From: J.B. Joret <jb(a)linux.vnet.ibm.com>
A hypervisor may allow to override the disk geometry of drives.
Qemu, as an example with cyls=,heads=,secs=[,trans=].
This patch extends the domain config to allow the specification of
disk geometry with libvirt.
V2 Changes: Split out qemu specific code, add documentation and schema.
V3 Changes: Moved geometry element to diskspec and use virReportError now.
V6 Changes: Generate geometry for all host device types.

after the --- line, as then it doesn't pollute the git history. It's
great for review purposes in email, but once the thread is over, no one
cares any longer how many revisions it took to get to the patch in git.

From: J.B. Joret <jb(a)linux.vnet.ibm.com>
Qemu command line generation for geometry override and testcases.
V2 Changes: squashed qemu code and testcases.
V3 Changes: use virReportError.
V4 Changes: rebase
V5 Changes: Fixed test invocation for geometry.
V6 Changes: Remove conditional geometry handling.
