Re: [libvirt] [PATCH 1/2] conf: Support for Block Device IO Limits

Introducing a new iolimits element allowing to override certain properties of a guest block device like the physical and logical block size. This can be useful for platforms with 'non-standard' disk formats like S390 DASD with its 4K block size.
