[Bug 1803575] [NEW] RFE: Add an option to enable virtio-scsi for new Nova instances by default
Public bug reported:
Description
===========
Currently virtio-scsi is used only for libvirt instances created from
the images with properties hw_scsi_model=virtio-scsi and
hw_disk_bus=scsi set or from the volumes with the same image metadata.
What is requested: config option in [libvirt] section of the nova.conf
to enable virtio-scsi for all new instances by default, even if
hw_scsi_model and hw_disk_bus properties for the image is not set.
Why: we want virtio-scsi to be enabled for VMs created from users images
even if they don't set this property explicitly, because we want to have
most of the vms be able to issue BLKDISCARD with fstrim.
** Affects: nova
Importance: Undecided
Status: New
