[libvirt] [PATCH 2/2] qemu: process: Report better error when virtlogd connection fails

When connecting to virtlogd fails e.g. due to wrong libvirtd selinux process label we'd report an utterly useless error message: $ virsh start upstream error: Failed to start domain upstream error: Cannot recv data: Connection reset by peer Use virLastErrorPrefixMessage in the correct place to give a better sense of what's going on: $ virsh start upstream error: Failed to start domain upstream error: can't connect to virtlogd: Cannot recv data: Connection reset by peer Signed-off-by: Peter Krempa <pkrempa(a)redhat.com&gt; --- src/qemu/qemu_process.c | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) diff --git a/src/qemu/qemu_process.c b/src/qemu/qemu_process.c index 50a76aa0ed..0ac3e0727b 100644 --- a/src/qemu/qemu_process.c +++ b/src/qemu/qemu_process.c @@ -6604,8 +6604,10 @@ qemuProcessLaunch(virConnectPtr conn, VIR_DEBUG("Creating domain log file"); if (!(logCtxt = qemuDomainLogContextNew(driver, vm, - QEMU_DOMAIN_LOG_CONTEXT_MODE_START))) + QEMU_DOMAIN_LOG_CONTEXT_MODE_START))) { + virLastErrorPrefixMessage("%s", _("can't connect to virtlogd")); goto cleanup; + } logfile = qemuDomainLogContextGetWriteFD(logCtxt); if (qemuProcessGenID(vm, flags) < 0) -- 2.21.0
