This patch series adds the functionality to detect a misconfiguration
between disk bus type and disk address type for disks that are using
the address type virDomainDeviceDriveAddress. It also adds a test for
it.
A check for other bus types may be needed. This may require a driver
specific function, as it is already implemented in
virDomainDeviceDefPostParse(), for example.
Changelog:
- v1 -> v2:
+ Use full enumeration of the bus types
+ Add warning for unexpected bus type

New subject: [libvirt] [PATCH v2 1/2] conf: Detect misconfiguration between disk bus and disk address
This patch detects a misconfiguration between the disk bus type and disk
address type for controller based disk buses (SATA, SCSI, FDC and
IDE). The addresses of these bus types are all managed in common code so
it's possible to decide in common code whether the disk address and bus
type are compatible or not.

As far as I've read, Roman has already created a new way for the bhyve
SATA address allocation in libvirt (thread
