instance.root_gb means size of host local disk used by the instance root disk. All code that uses this attribute treats it that way.
Volume-backed instances have root disks placed in Cinder. Therefore obviously root_gb should be 0 for them. However currently this is not so. The same applies to min_size and size image attributes, used for boot from a volume.
As a result the code which uses these attributes works incorrectly. Some problems are already detected [1], other are not yet [2].
To fix all these problems fully it is proposed to set root_gb, min_size, size to 0 for volume-backed instances.

As a result the code which uses these attributes works incorrectly. Some problems are already detected [1], other are not yet [2].
There are two kinds of bugs:
1 Nova fails to launch an instance from a large volume if the volume size (or an original image's min_disk) is greater than requested flavor.disk.
2 Nova incorrectly calculates host disk space consumed by volume-backed instances.
To fix all these problems fully it is proposed to set root_gb, min_disk, size to 0 for volume-backed instances.
