Thanks for the advice! I can find the new device in xenstore-ls, but the OS code cannot read it out. Is it possible to *remove* some xenstore nodes, if the code is too wrong? Below is the output from one run of Ethos OS, with xl -vvv. It will crash and destroy the domain, so I won't see xenstore stuff afterwards. But it looks to me that the devices are added. Note that I added code to read vif1, vif0, then vbd, and got output below. (My apology if I dumped too much stuff here.)
