We test a couple of hypervisor call here (done via ioctl), could you see if all the ioctl failed ? Then assuming it goes though we go look up the version later in that function (at detect_v2) and call virXen_getdomaininfo() to do so, could you trace through it and virXen_getdomaininfolist() to see what actually happens ? thanks a lot !
