Message-ID: <155514522514.793.7421956223092571453.report...@buster.jfalk.de> X-Mailer: reportbug 7.5.2 Date: Sat, 13 Apr 2019 10:47:05 +0200 Package: libvirt-daemon Version: 5.0.0-1 Severity: grave Tags: upstream Justification: renders package unusable Dear maintainer, there is a problem with killing LXC containers when only one cgroup backend is available. Cgroup backend v2 is not available on the default install of libvirt-daemon-system and, thus, killing LXC containers fails. This seemes to be fixed by upstream with commit 401030499bfb03b182da14f7e00f4a82beab9a8e ====================================================================== >From 401030499bfb03b182da14f7e00f4a82beab9a8e Mon Sep 17 00:00:00 2001 From: Michal Privoznik <mpriv...@redhat.com> Date: Thu, 24 Jan 2019 17:20:58 +0100 Subject: [PATCH] vircgroup: Try harder to kill cgroup Prior to rewrite of cgroup code we only had one backend to try. After the rewrite the virCgroupBackendGetAll() returns both backends (for v1 and v2). However, not both have to really be present on the system which results in killRecursive callback failing which in turn might mean we won't try the other backend. At the same time, this function reports no error as it should. ====================================================================== This commit is also part of upstream version 5.1.0. Hence, a bump to a newer upstream should also fix the issue. Symptoms of the problem are as follows in /var/log/libvirt/libvirtd.log: 2019-04-13 08:10:17.708+0000: 532: debug : virLXCDomainObjBeginJob:108 : Starting job: modify 2019-04-13 08:10:17.708+0000: 532: debug : virLXCProcessStop:831 : Stopping VM name=flummy pid=701 reason=2 2019-04-13 08:10:17.708+0000: 532: debug : virCgroupKillPainfully:2647 : cgroup=0x7f5f38005c50 path= 2019-04-13 08:10:17.708+0000: 532: debug : virCgroupKillRecursive:2617 : group=0x7f5f38005c50 path= signum=15 2019-04-13 08:10:17.708+0000: 532: debug : virCgroupKillPainfully:2658 : Iteration 0 rc=-1 2019-04-13 08:10:17.708+0000: 532: debug : virCgroupKillPainfully:2665 : Complete -1 2019-04-13 08:10:17.708+0000: 532: info : virObjectNew:248 : OBJECT_NEW: obj=0x7f5f24001b20 classname=virDomainEventLifecycle 2019-04-13 08:10:17.708+0000: 532: debug : virLXCDomainObjEndJob:146 : Stopping job: modify You have to enable debugging to get these logs, i.e., --- libvirtd.conf.orig 2019-03-30 19:43:46.110699728 +0100 +++ libvirtd.conf 2019-03-30 19:47:37.306130440 +0100 @@ -389,6 +389,7 @@ # rest of the util code: # #log_filters="1:qemu 1:libvirt 4:object 4:json 4:event 1:util" +log_filters="3:remote 4:event 3:json 3:rpc 1:*" # Logging outputs: # An output is one of the places to save logging information @@ -411,7 +412,7 @@ # e.g. to log all warnings and errors to syslog under the libvirtd ident: #log_outputs="3:syslog:libvirtd" # - +log_outputs="1:file:/var/log/libvirt/libvirtd.log 3:syslog:libvirtd" ################################################################## # Best, Joachim Falk -- System Information: Debian Release: buster/sid APT prefers testing APT policy: (500, 'testing') Architecture: amd64 (x86_64) Kernel: Linux 4.19.0-4-amd64 (SMP w/4 CPU cores) Locale: LANG=de_DE.UTF-8, LC_CTYPE=de_DE.UTF-8 (charmap=UTF-8), LANGUAGE=de_DE.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /usr/bin/dash Init: systemd (via /run/systemd/system) Versions of packages libvirt-daemon depends on: ii libacl1 2.2.53-4 ii libapparmor1 2.13.2-10 ii libaudit1 1:2.8.4-2 ii libavahi-client3 0.7-4+b1 ii libavahi-common3 0.7-4+b1 ii libblkid1 2.33.1-0.1 ii libc6 2.28-8 ii libcap-ng0 0.7.9-2 ii libcurl3-gnutls 7.64.0-2 ii libdbus-1-3 1.12.12-1 ii libdevmapper1.02.1 2:1.02.155-2 ii libfuse2 2.9.9-1 ii libgcc1 1:8.3.0-5 ii libgnutls30 3.6.6-2 ii libnetcf1 1:0.2.8-1+b2 ii libnl-3-200 3.4.0-1 ii libnl-route-3-200 3.4.0-1 ii libnuma1 2.0.12-1 ii libparted2 3.2-24 ii libpcap0.8 1.8.1-6 ii libpciaccess0 0.14-1 ii libsasl2-2 2.1.27+dfsg-1 ii libselinux1 2.8-1+b1 ii libssh2-1 1.8.0-2.1 ii libudev1 241-3 ii libvirt0 5.0.0-1 ii libxenmisc4.11 4.11.1+26-g87f51bf366-3 ii libxenstore3.0 4.11.1+26-g87f51bf366-3 ii libxentoollog1 4.11.1+26-g87f51bf366-3 ii libxml2 2.9.4+dfsg1-7+b3 ii libyajl2 2.1.0-3 Versions of packages libvirt-daemon recommends: ii libxml2-utils 2.9.4+dfsg1-7+b3 ii netcat-openbsd 1.195-2 ii qemu-kvm 1:3.1+dfsg-7 Versions of packages libvirt-daemon suggests: pn libvirt-daemon-driver-storage-gluster <none> pn libvirt-daemon-driver-storage-rbd <none> pn libvirt-daemon-driver-storage-zfs <none> ii libvirt-daemon-system 5.0.0-1 pn numad <none> -- no debconf information -- System Information: Debian Release: buster/sid APT prefers testing APT policy: (500, 'testing') Architecture: amd64 (x86_64) Kernel: Linux 4.19.0-4-amd64 (SMP w/4 CPU cores) Locale: LANG=de_DE.UTF-8, LC_CTYPE=de_DE.UTF-8 (charmap=UTF-8), LANGUAGE=de_DE.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /usr/bin/dash Init: systemd (via /run/systemd/system) Versions of packages libvirt-daemon depends on: ii libacl1 2.2.53-4 ii libapparmor1 2.13.2-10 ii libaudit1 1:2.8.4-2 ii libavahi-client3 0.7-4+b1 ii libavahi-common3 0.7-4+b1 ii libblkid1 2.33.1-0.1 ii libc6 2.28-8 ii libcap-ng0 0.7.9-2 ii libcurl3-gnutls 7.64.0-2 ii libdbus-1-3 1.12.12-1 ii libdevmapper1.02.1 2:1.02.155-2 ii libfuse2 2.9.9-1 ii libgcc1 1:8.3.0-5 ii libgnutls30 3.6.6-2 ii libnetcf1 1:0.2.8-1+b2 ii libnl-3-200 3.4.0-1 ii libnl-route-3-200 3.4.0-1 ii libnuma1 2.0.12-1 ii libparted2 3.2-24 ii libpcap0.8 1.8.1-6 ii libpciaccess0 0.14-1 ii libsasl2-2 2.1.27+dfsg-1 ii libselinux1 2.8-1+b1 ii libssh2-1 1.8.0-2.1 ii libudev1 241-3 ii libvirt0 5.0.0-1 ii libxenmisc4.11 4.11.1+26-g87f51bf366-3 ii libxenstore3.0 4.11.1+26-g87f51bf366-3 ii libxentoollog1 4.11.1+26-g87f51bf366-3 ii libxml2 2.9.4+dfsg1-7+b3 ii libyajl2 2.1.0-3 Versions of packages libvirt-daemon recommends: ii libxml2-utils 2.9.4+dfsg1-7+b3 ii netcat-openbsd 1.195-2 ii qemu-kvm 1:3.1+dfsg-7 Versions of packages libvirt-daemon suggests: pn libvirt-daemon-driver-storage-gluster <none> pn libvirt-daemon-driver-storage-rbd <none> pn libvirt-daemon-driver-storage-zfs <none> ii libvirt-daemon-system 5.0.0-1 pn numad <none> -- no debconf information
