One more - i tried do debug this problem with the debug-enviroment variable - it seems like libvirt can't connect the qemu hypervisor ... Hmm, in xen-enviroment, there's a xend daemon running - but in qemu-enviroment ? There's no separate daemon "qemud" or similar running ... so, again's which or what will libvirt try to connect to ? Maybe a remote access to from libirt to qemu CAN NOT work ? maybe this would be a additional info for libvirt-docu ? regards Danny [root@xen03 ~]# LIBVIRT_DEBUG=SPAM virsh -c qemu+tls://xxx03.domainname.com DEBUG: libvirt.c: virInitialize (register drivers) DEBUG: libvirt.c: virRegisterDriver (registering Test as driver 0) DEBUG: libvirt.c: virRegisterNetworkDriver (registering Test as network driver 0) DEBUG: libvirt.c: virRegisterStorageDriver (registering Test as storage driver 0) DEBUG: libvirt.c: virRegisterDriver (registering Xen as driver 1) DEBUG: libvirt.c: virRegisterDriver (registering OPENVZ as driver 2) DEBUG: libvirt.c: virRegisterDriver (registering remote as driver 3) DEBUG: libvirt.c: virRegisterNetworkDriver (registering remote as network driver 1) DEBUG: libvirt.c: virRegisterStorageDriver (registering remote as storage driver 1) DEBUG: libvirt.c: virRegisterDeviceMonitor (registering remote as device driver 0) DEBUG: libvirt.c: virConnectOpenAuth (name=qemu+tls://xxx03.domainname.com, auth=0x35ce2930a0, flags=0) DEBUG: libvirt.c: do_open (name "qemu+tls://xxx03.domainname.com" to URI components: scheme qemu+tls opaque (null) authority (null) server xxx03.domainname.com user (null) port 0 path ) DEBUG: libvirt.c: do_open (trying driver 0 (Test) ...)
