I know /dev/sda* is KVM boot partitions.So,how do they work? Besides,I have a volume whose device_id.to_i=1,so what's the device_name it equals to? /dev/sda or /dev/sdb? How does cloudstack calculate it? What's the start number of cloudstack device_id?0 or 1? Thanks! ----- Best regards, DuJun --001a11c3675e2750cb04ec013532--
