Hi Fajar,

Thanks. It is wired. I did have CONFIG_XEN_BLKDEV_TAP=m when I compile, and 
have blktap module loaded when the system boot. But when I start a domu with 
tap:aio indicator, I encounter the message on the domu console as below:
XENBUS: Waiting for devices to initialize: 295s...290s...
Until 300s time out. And the corresponding filesystem fails to be mounted.
When I replace tap:aio with file, problem solved.

Any idea?
