I'm going though your code right now. I find something suspicious: in xenHypervisorGetSchedulerParameters you check /* * Support only dom_interface_version >=5 * (Xen3.1.0 or later) */ if (dom_interface_version < 5) { virXenError(VIR_ERR_NO_XEN, "xenHypervisorGetSchedulerParameters unsupported in dom interface < 5", 0); return -1; } And I don't see why ! The two next hypercalls, the system one to get the scheduler ID and the domain one to get the scheduler parameters both exist on the xen-3.03 available for example in RHEL-5.0. So why exit with an error there ?
