 contains:
        [2012-02-09 22:34:26 2310] ERROR (XendDomainInfo:488) VM start failed
        Traceback (most recent call last):

This try block contains only a single call to
xen.xend.xenstore.xsutil.IntroduceDomain which ultimately turns into a C
call to xs_introduce_domain.

Daniel, I'm afraid I suspect the XS stubdom series for this one. My
suspicion is a missing call to seed_grant_table from xend (or from a
libxc function which xend uses) which prevents xenstored from mapping
the guest's ring, which results in an error from map_interface() in
xenstored.

Ian.
