No, it doesn't. Linux definitely thinks the vbd has zero size so never even gets to try to read a partition table. I followed what you did exactly, and without an explicit poll of Xen it definitely didn't work. I'd like to see how your machine setup is different -- for example, are you sure the /dev/vbd* nodes have the right device numbers? (Should be major = 125, minor = (vbd_id*16)+partition). I'm going to have some more of a look at the blkdev stuff now, but it would be nice to know how come it's been "working" for you. -- Keir ------------------------------------------------------- This SF.net email is sponsored by: SF.net Giveback Program.
