BZ:https://bugzilla.redhat.com/show_bug.cgi?id=912021 Without error handler set, virDefaultErrorFunc will be called, the error message is prefixed with "libvir:". It become a little better by using prefix "libvirt:" when working with upper application. For example: 1, stop libvirtd daemon 2, run virt-top. libvir: XML-RPC error : Failed to connect \ socket to '/var/run/libvirt/libvirt-sock-ro': \ No such file or directory libvirt: VIR_ERR_SYSTEM_ERROR: VIR_FROM_RPC: \ Failed to connect socket to '/var/run/libvirt/libvirt-sock-ro': \ No such file or directory --- src/util/virerror.c | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) diff --git a/src/util/virerror.c b/src/util/virerror.c index 301a1ac..40c3b25 100644 --- a/src/util/virerror.c +++ b/src/util/virerror.c @@ -525,13 +525,13 @@ virDefaultErrorFunc(virErrorPtr err) len = strlen(err->message); if ((err->domain == VIR_FROM_XML) && (err->code == VIR_ERR_XML_DETAIL) && (err->int1 != 0)) - fprintf(stderr, "libvir: %s %s %s%s: line %d: %s", + fprintf(stderr, "libvirt: %s %s %s%s: line %d: %s", dom, lvl, domain, network, err->int1, err->message); else if ((len == 0) || (err->message[len - 1] != '\n')) - fprintf(stderr, "libvir: %s %s %s%s: %s\n", + fprintf(stderr, "libvirt: %s %s %s%s: %s\n", dom, lvl, domain, network, err->message); else - fprintf(stderr, "libvir: %s %s %s%s: %s", + fprintf(stderr, "libvirt: %s %s %s%s: %s", dom, lvl, domain, network, err->message); } -- 1.7.11.2
