commit ed994bb4d72b5f93cfb76a5f726264e4896ad4ed Author: Feodor Tersin <[email protected]> Date: Tue Oct 4 20:17:17 2016 +0300 libvirt: Improve _is_booted_from_volume implementation Currently this method cannot be used widely due to its parameters. It requires device_info - the dict which can not be easily obtained in many cases. Since it is often needed to figure out if an instance is booted from volume, and the method name is "appropriate", this sometimes leads to errors (when string result of get_instance_disk_info is passed as an argument to _is_booted_from_volume; see also Id5901254). This patch makes _is_booted_from_volume to use standard block_device_info structure, which is accessible in almost any driver method.
