--- Begin Message ---Package: qemu-kvm Version: 1.1.2+dfsg-2 Severity: critical Tags: upstream We (Univention) noticed a serious data loss problem with qemu-kvm-1.1.2 as currently shipped with Debain wheezy (and our own Debian based distribution UCS). After finding that issue in our distribution I also verified that it exists with a plain Debian wheezy setup. The bug is also present in qemu-kvm-1.1.2 as compiled from git, but is not present in qemu-kvm-1.2.0, so it's an upstream problem. I bisected the problem down to b7ab0fea37c15ca9e249c42c46f5c48fd1a0943c "qcow2: Fix avail_sectors in cluster allocation code" fixing the problem. I asked the author of said patch for his opinion, but he can't thinks of why that patch would fix the problem. <http://lists.nongnu.org/archive/html/qemu-devel/2012-12/msg01537.html> I'm currently continuing to investigate the problem and will keep you informed. The bug is tracked in our German bugzilla at <https://forge.univention.org/bugzilla/show_bug.cgi?id=29355> where you can find further technical details. The bug manifests as MD5 and unpacking errors during package install, programs failing to start and file system corruption. It mostly happens with qcow2 files which use other qcow2 files as a backing file, but we've seen errors on plain qcow2 installations as well. -- Package-specific info: /proc/cpuinfo: processor : 0 .... processor : 7 vendor_id : GenuineIntel cpu family : 6 model : 30 model name : Intel(R) Core(TM) i7 CPU 860 @ 2.80GHz stepping : 5 microcode : 0x4 cpu MHz : 1200.000 cache size : 8192 KB physical id : 0 siblings : 8 core id : 0 cpu cores : 4 apicid : 0 initial apicid : 0 fpu : yes fpu_exception : yes cpuid level : 11 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe syscall nx rdtscp lm constant_tsc arch_perfmon pebs bts rep_good nopl xtopology nonstop_tsc aperfmperf pni dtes64 monitor ds_cpl vmx smx est tm2 ssse3 cx16 xtpr pdcm sse4_1 sse4_2 popcnt lahf_lm ida dtherm tpr_shadow vnmi flexpriority ept vpid bogomips : 5600.20 clflush size : 64 cache_alignment : 64 address sizes : 36 bits physical, 48 bits virtual power management: -- System Information: Debian Release: wheezy/sid APT prefers testing APT policy: (500, 'testing') Architecture: amd64 (x86_64) Kernel: Linux 3.2.0-4-amd64 (SMP w/8 CPU cores) Locale: LANG=de_DE.UTF-8, LC_CTYPE=de_DE.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Versions of packages qemu-kvm depends on: ii adduser 3.113+nmu3 ii ipxe-qemu 1.0.0+git-20120202.f6840ba-3 ii libaio1 0.3.109-3 ii libasound2 1.0.25-4 ii libbluetooth3 4.99-2 ii libbrlapi0.5 4.4-5 ii libc6 2.13-37 ii libcurl3-gnutls 7.26.0-1 ii libglib2.0-0 2.33.12+really2.32.4-3 ii libgnutls26 2.12.20-2 ii libiscsi1 1.4.0-3 ii libjpeg8 8d-1 ii libncurses5 5.9-10 ii libpng12-0 1.2.49-1 ii libpulse0 2.0-6 ii libsasl2-2 2.1.25.dfsg1-6 ii libsdl1.2debian 1.2.15-5 ii libspice-server1 0.11.0-1 ii libtinfo5 5.9-10 ii libusbredirparser0 0.4.3-2 ii libuuid1 2.20.1-5.2 ii libvdeplug2 2.3.2-4 ii libx11-6 2:1.5.0-1 ii python 2.7.3~rc2-1 ii qemu-keymaps 1.1.2+dfsg-2 ii qemu-utils 1.1.2+dfsg-2 ii seabios 1.7.0-1 ii vgabios 0.7a-3 ii zlib1g 1:1.2.7.dfsg-13 Versions of packages qemu-kvm recommends: ii bridge-utils 1.5-6 ii iproute 20120521-3 Versions of packages qemu-kvm suggests: pn debootstrap <none> pn samba <none> pn vde2 <none> -- no debconf information
