Report an error early instead of trying to start it. https://bugzilla.redhat.com/show_bug.cgi?id=1155410 --- src/lxc/lxc_container.c | 6 ++++-- src/lxc/lxc_process.c | 6 ++++++ 2 files changed, 10 insertions(+), 2 deletions(-) diff --git a/src/lxc/lxc_container.c b/src/lxc/lxc_container.c index f02b959..8aba3ba 100644 --- a/src/lxc/lxc_container.c +++ b/src/lxc/lxc_container.c @@ -2093,8 +2093,10 @@ static int lxcContainerChild(void *data) if (virAsprintf(&ttyPath, "%s/%s.devpts/%s", LXC_STATE_DIR, vmDef->name, tty) < 0) goto cleanup; - } else if (VIR_STRDUP(ttyPath, "/dev/null") < 0) { - goto cleanup; + } else { + virReportError(VIR_ERR_INTERNAL_ERROR, "%s", + _("At least one tty is required")); + goto cleanup; }
