As Andy figured out correctly, the xencapstest calls xenHypervisorMakeCapabilitiesInternal with conn == NULL. xenHypervisorMakeCapabilitiesInternal then calls xenDaemonNodeGetTopology with conn == NULL if sys_interface_version >= SYS_IFACE_MIN_VERS_NUMA holds. This is true when you have Xen installed, otherwise sys_interface_version is -1. Therefore this test will fail when ypu have recent Xen installed. I just remember this, because Jim mentioned it quite a while ago on IRC and I looked up the details in my logs. At that time I suggested to apply this patch/hack to avoid the problem, as xenDaemonNodeGetTopology want to talk to a real xend at that point and insists in conn != NULL for that. diff --git a/src/xen/xen_hypervisor.c b/src/xen/xen_hypervisor.c index c5cc880..95b3ca2 100644 --- a/src/xen/xen_hypervisor.c +++ b/src/xen/xen_hypervisor.c @@ -2244,8 +2244,7 @@ xenHypervisorBuildCapabilities(virConnectPtr conn, "xenmigr") < 0) goto no_memory; - - if (sys_interface_version >= SYS_IFACE_MIN_VERS_NUMA) { + if (sys_interface_version >= SYS_IFACE_MIN_VERS_NUMA && conn != NULL) { if (xenDaemonNodeGetTopology(conn, caps) != 0) { virCapabilitiesFree(caps); return NULL; I'm not sure why the interfaceschematest fails, as It works for me.
