[libvirt] [PATCH] qemu: Fix error reporting in qemuDomainSaveImageStartVM
by Jiri Denemark 18 Sep '18

18 Sep '18

When restoring a domain from a compressed image, we launch an intermediate process for decompressing the saved data. If QEMU fails to load the data for some reason, we force close the stdin/stdout file descriptors of the intermediate process and wait for it to die. However, virCommandWait can report various errors which would overwrite the real error from QEMU. Thus instead of getting something useful: internal error: process exited while connecting to monitor: 2018-09-17T15:17:29.998910Z qemu-system-x86_64: can't apply global Skylake-Client-x86_64-cpu.osxsave=off: Property '.osxsave' not found we could get an irrelevant error message: internal error: Child process (lzop -dc --ignore-warn) unexpected fatal signal 13 Signed-off-by: Jiri Denemark <jdenemar(a)redhat.com> --- src/qemu/qemu_driver.c | 11 ++++++++++- 1 file changed, 10 insertions(+), 1 deletion(-) diff --git a/src/qemu/qemu_driver.c b/src/qemu/qemu_driver.c index 9424994aa1..25cbccc5e6 100644 --- a/src/qemu/qemu_driver.c +++ b/src/qemu/qemu_driver.c @@ -6590,11 +6590,15 @@ qemuDomainSaveImageStartVM(virConnectPtr conn, restored = true; if (intermediatefd != -1) { + virErrorPtr orig_err = NULL; + if (!restored) { /* if there was an error setting up qemu, the intermediate * process will wait forever to write to stdout, so we - * must manually kill it. + * must manually kill it and ignore any error related to + * the process */ + orig_err = virSaveLastError(); VIR_FORCE_CLOSE(intermediatefd); VIR_FORCE_CLOSE(*fd); } @@ -6604,6 +6608,11 @@ qemuDomainSaveImageStartVM(virConnectPtr conn, restored = false; } VIR_DEBUG("Decompression binary stderr: %s", NULLSTR(errbuf)); + + if (orig_err) { + virSetError(orig_err); + virFreeError(orig_err); + } } VIR_FORCE_CLOSE(intermediatefd); -- 2.19.0

[libvirt] [libvirt PATCH v5 0/1] Finish the conversion to virConfGetValue* functions
by Fabiano Fidêncio 18 Sep '18

18 Sep '18

This patchset finishes the conversion to virConfGetValue* functions, started by Daniel Berrange a few months ago. Please, mind that although we could make virConfGetValue* functions more generic in order to support numbers and booleans as strings, that doesn't seem the safest path to take. The side-effect of this is that we will have to live with some specific code doing that as part of vmx and xen_common. Once this patchset gets merged, https://wiki.libvirt.org/page/BiteSizedTasks#Finish_conversion_to_virConfGe… can be removed. - Changes since v1: All the "values" from virConfGetValueString() are freed - Changes since v2: All comments from Ján Tomko have been addressed; A few leaks were (possibly) found and they're addressed in the last patch of the series; - Changes since v3: All comments from Ján Tomko have been addressed in order to lower the non-whitespace changes in the first patch; - Chages since v4: All comments from Ján Tomko have been addressed (hopefully, they actually were this time :-)); Fabiano Fidêncio (1): xen_common: Convert to typesafe virConf acessors src/xenconfig/xen_common.c | 163 +++++++++++++++++-------------------- 1 file changed, 75 insertions(+), 88 deletions(-) -- 2.17.1

What happens when we can hotplug the primary display? Aren't disabling hotplug of a vfio-pci device and supporting ramfb two separate things? I think we're leaking current implementation issues out to the device options when really we'd rather have a "ramfb" (or perhaps "console") option on the vfio-pci device and the hotplug capability determined automatically and available through introspection of the device. Thanks, Alex
