LinuxQuestions.org - Xen4.1 error: Device model isn't ready for commands

Hi everyone,

I have been learning Xen+Debian for about two weeks now. I followed a few online tutorial to setup my home server using Xen4.1 (Debian Wheezy). My main goal is VGA, audio passthrough to HVM windows domU for XBMC media playback and another domU for OpenMediaVault for NAS.

So far, I have managed to assign the VGA and usb to xen-pciback. And when I 'xm create' my .cfg file, I had the error as following:

Error: Device model isn't ready for commands

I looked into the log, and I couldn't understand much. Could anyone help me interpret this log and point me to the right direction? Thanks in advance!!!!
