Re: [libvirt] [PATCH] virsh domxml-from-native to treat SCSI as the bus type for pseries by default

From: Shivaprasad G Bhat <shivaprasadbhat(a)gmail.com&gt; The bus type IDE being enum Zero, the bus type on pseries system appears as IDE for all the -hda/-cdrom and for disk drives with if="none" type. Pseries platform needs this to appear as SCSI instead of IDE. The ide being not supported, the explicit requests for ide devices will return an error.
