I'm not intimately familiar with the other bugs currently filed for the
'hotplug scripts not working' issue, so please excuse me if this doesn't apply
or you already know of it - but in my experience, when I get that problem
trying to 'xm create', it means that my udev daemon (on dom0) has gone AWOL.
Simply doing an '/etc/init.d/udev start' to bring udev back up always seems to
fix the problem for me.

I suspect the same thing afflicts you given your mention of rebooting fixing
the problem. While this is obviously not a great state of affairs, running the
udev init script to restart udev is clearly a better solution than a physical
restart.

I have not noticed any issues with currently-running domUs when this issue
comes up, FWIW: they don't hiccup or have any other problems. The problem seems
isolated to the creation of new domU processes only.

Hope this helps somewhat...
