Description RHOS Integration 2014-02-19 22:05:24 UTC
Cloned from launchpad blueprint


Libvirt/qemu have supported trim command for the qcow2(after qemu1.6)/raw(after qemu1.5) foramt disk。

This blueprint aims to provide the feature to enable tirm option.
User can enable it for the volume by specifing the metadata. Then when the volume is attachedto the instance, the discard option will be setted.
Because of the discard option is only supported when bus is scsi or ide, this feature will also add bus option setting for the volume by metadata.
