[libvirt] [PATCH] virsh domxml-from-native to treat SCSI as the bus type for pseries by default
From: Shivaprasad G Bhat <sbhat@linux.vnet.ibm.com> The bus type IDE being enum Zero, the bus type on pseries system appears as IDE for all the disk types. Pseries platform needs this to appear as SCSI instead of IDE.

I'm wondering if we should reuse our post-XML-parse callbacks here, rather than open-coding a machine check. In other words, since we already have code that knows how to do per-machine fixups to a domain definition, we should be reusing those instead of open-coding duplicate checks. (Actually, domxml-from-native needs a LOT of TLC, there's much more wrong with it, even on non-pseries machines, than what you are trying to patch). -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
