Saw a strange problem. When blkfront writes event channel number and ring-ref to xenstore, the watch registered by blkback is notified. However immediately watch handler in blkback found there's no "physical-device" under xenstore which should refer to major/minor number of device for domU. Then failed to create vbd and finally the connection can't be setup. So my puzzle is, when should physical-device be created? And who creates this item? I searched for name string in whole tools directory to only find instance in block-file/block-phy/block-endb. I configured disk image by /dev/loop0, so ideally block-phy should be used. However I still failed to find where block-phy is invoked. Any clues?
