I think this is a  bug in the Xen driver - the  virDomainCreate 
api is not updating the internal 'id' parameter of the virDomainPtr
object, so when you then call virDomainSuspend() with the same
virDomainPtr it doesn't have the id it needs

The easy workaround is to just get rid of your existing dom object
and lookup a new one with 'virDomainLoopByUUID' after starting it.

     virDomainPtr dom;
     char  uuid[VIR_UUID_BUFLEN];

     virDomainCreate(dom);

     virDomainGetUUID(dom, uuid);
     virDomainFree(dom);
     dom = virDomainLookupByUUID(conn, uuid);

     virDomainSuspend(dom);
