You are probably aware of this but FYI...

I used virDomainReboot() with success when the domain was created with 
"xm create" and "on_reboot = 'restart'" in domain config file.

Looking at virDomainParseXMLDesc() in xml.c I see we are not accounting 
for a <on_reboot> element (or on_crash, on_poweroff) in the XML.  Are 
you working on this Daniel or should I take a stab at it?  I'm guessing 
you just want elements like

<on_reboot>restart</on_reboot>
<on_poweroff>destroy</on_poweroff>
<on_crash>restart</on_crash>

Same goes turning sxp to XML in xend_parse_sexp_desc() in xend_internal.c.
