Explain why people should be using the "raw" image format for RBD volumes created for use by QEMU: using any other format adds only overhead, but no extra value (since RBDs are also CoW and thin-provisioned), plus the Qcow2 storage driver is not migration safe when caching is enabled, whereas the RBD driver is. Also, fix a minor glitch in the example qemu-img commands ("-f rbd" and "-O rbd" should really be "-f raw" and "-O raw"). Finally, drop the "-f" option altogether on qemu-img commands where it makes no sense (info and resize). Signed-off-by: Florian Haas <florian@hastexo.com> |
