[libvirt] [PATCH] qemu: improve error message on failed fd transfer

First fallout of fd: migration - it looks like SELinux enforcing _does_ require fd labeling (running uninstalled libvirtd from an unconstrained shell had no problems, but once faked out by doing chcon `stat -c %C /usr/sbin/libvirtd` daemon/libvirtd run_init $PWD/daemon/libvirtd to run it with the same context as an init script service, and with SELinux enforcing, I got a rather confusing failure: error: Failed to save domain fedora_12 to fed12.img error: internal error unable to send TAP file handle: No file descriptor supplied via SCM_RIGHTS This fixes the error message, then I need to figure out a subsequent patch that does the fsetfilecon() necessary to keep things happy. It also appears that libvirtd hangs on a failed fd transfer; I don't know if that needs an independent fix. * src/qemu/qemu_monitor_text.c (qemuMonitorTextSendFileHandle): Improve message, since TAP is no longer only client. --- src/qemu/qemu_monitor_text.c | 4 ++-- 1 files changed, 2 insertions(+), 2 deletions(-) diff --git a/src/qemu/qemu_monitor_text.c b/src/qemu/qemu_monitor_text.c index 75b2995..5b1290b 100644 --- a/src/qemu/qemu_monitor_text.c +++ b/src/qemu/qemu_monitor_text.c @@ -1679,0 +1679,0 @@ int qemuMonitorTextSendFileHandle(qemuMonitorPtr mon, if (STRNEQ(reply, "")) { qemuReportError(VIR_ERR_INTERNAL_ERROR, - _("unable to send TAP file handle: %s"), - reply); + _("unable to send file handle '%s': %s"), + fdname, reply); goto cleanup; } -- 1.7.4
