[CentOS-virt] Why is SCSI disabled in kvm on CentOS 5.8?

2012-10-02 Thread Bill Campbell
Looking at the SRPM kvm-83-249.el5.centos.5, and the SRPM for
qemu-kvm-0.12.1.2-2.209.el6.src.rpm on CentOS 6.2, I see many
patches to remove SCSI support.  The 5.2 kvm.spec file disables
scsi in the configure run.

Why has this been disabled?  Many old OS's don't grok SATA, but
have had SCSI support for years.

It does not require a majority to prevail, but rather an irate, tireless
minority keen to set brush fires in people's minds. -- Samuel Adams

Upstream probably doesn't support SCSI drivers because they are not much
used as IDE or Virtio.
In Centos 6.3 you probably want to use the new virtio-scsi driver which
looks like it will become the new standard driver because of its features.
