That looks normal to me.  The "b" stands for "blocked" i.e. it's probably 
waiting for IO from disk or network.  On a uniprocessor system you'll never 
actually a domain other than dom0 in the "r" (running) state - since in order 
to run xm list, dom0 has to be in the act of running.  On a multiprocessor 
system, a domain which is doing lots of IO, or not using the CPU much, or 
sharing with other domains is also going to spend quite a lot of time not in 
the "r" state.

Does the CPU time usage displayed by xm list go up?  If you use xm console, 
can you connect to the domain?  I suspect the domain has started OK, but 
possibly its not displaying the console correctly or something.  It looks 
like it's running tho...

Cheers,
Mark
