Re: [Xen-devel] can't start domains

[Ian Pratt <Ian.Pratt@xxxxxxxxxxxx>]

Something is going wrong during the domain creation, and then
xend tries to clean up by destroying the stillborn
domain. Unfortunately, we then hit a xend bug while destroying
the domain's block device (perhaps because that was the original
problem?) and the traceback all refers to this bug which prevents
it from reporting back to xm what the original problem was.

I've cc'ed Mike so that he can take a look at the Xend bug. 

As regards the real error, take a close look at the sxp config
data that that xm sends to xend and check that it matches your
expected configuration. (see the config: output from xend).
