[PATCH] virtinst:change default disk bus type into scsi on pseries machine

[Qing Lin <qinglbj@xxxxxxxxxxxxxxxxxx>]

When install OS from cdrom ,the default cdrom disk bus type is "ide",
which is not supported on pseries machine.But there is no interface to 
change it through the whole install process.So we should set "scsi"
(pseries machine support) as default disk type on pseries machine.
