Disk targets were generated in virVMXParseConfig() with virVMXGenerateDiskTarget(). It works on combination of controller, fix offset, unit and prefix. While SCSI and SATA have same prefix "sd", function virVMXGenerateDiskTarget() could returned in some cases same targets. In this patch, after loaded SCSI and SATA disks to the def, it checks if in array exists any SATA disks after SCSI. If not, nothing happened. If yes, targets of all SATA disks are changed. Disk target is calculated as: last SCSI target value + n, where n is position of disk in array after last SCSI (1,2,..). Because assigned addresses of disks are generated from their indexes, for every changed SATA disk is called virDomainDiskDefAssignAddress() with the updated value. The corresponding tests have been modified to match the index changes.

It works on combination of controller, fix offset, unit and prefix. While SCSI and SATA have same prefix "sd", function virVMXGenerateDiskTarget() could returned in some cases same targets. In this patch, after loaded SCSI and SATA disks to the def, indexes are regenerated, now simply from position of the disk in array of disks (def). With this, required uniqueness is guaranteed.

Signed-off-by: Adam Julis <ajulis@redhat.com> --- Since previous version in mailing list was complicated for trying to preserve the indexes of SCSI and previous tests, this one going to straightforward, although it changes all (SCSI and SATA) indexes.
