Are you using the prebuilt unprivileged-domain kernel image? If so, the one in 2.0.1 at least (maybe others, not sure) has devfs support enabled. This breaks things. I suggest you rebuild your domU kernel _without_ devfs support, and it should work correctly. I had this same problem when I began playing with Xen, but after rebuilding the kernel as I mentioned, it all worked correctly. -- Derrik Pates dpates@dsdk12.net ------------------------------------------------------- SF email is sponsored by - The IT Product Guide Read honest & candid reviews on hundreds of IT Products from real users.
