** Description changed: My Win7 VM running on KVM keeps crashing lately. I cannot say when it started to do so but I can say that this was not happening at all some weeks ago. From the qemu-kvm log file related to this VM just after the crash I have found what follows: 2014-05-16 08:37:14.597+0000: starting up - LC_ALL=C PATH=/usr/local/sbin:/usr/local/bin:/usr/bin:/usr/sbin:/sbin:/bin QEMU_AUDIO_DRV=none /usr/bin/kvm -S -M pc-1.0 -cpu core2duo,+lahf_lm,+popcnt,+sse4.2,+sse4.1,+cx16,-monitor,-vme -enable-kvm -m 1024 -smp 1,sockets=1,cores=1,threads=1 -name win7-32 -uuid 9c5a2a97-7657-add4-2c4a-b9f1f8c076bd -nodefconfig -nodefaults -chardev socket,id=charmonitor,path=/var/lib/libvirt/qemu/win7-32.monitor,server,nowait -mon chardev=charmonitor,id=monitor,mode=control -rtc base=localtime -no-shutdown -drive file=/host/Users/stefano.doni/Desktop/KVM/win7-32.img,if=none,id=drive-ide0-0-0,format=raw -device ide-drive,bus=ide.0,unit=0,drive=drive-ide0-0-0,id=ide0-0-0,bootindex=1 -drive if=none,media=cdrom,id=drive-ide0-1-0,readonly=on,format=raw -device ide-drive,bus=ide.1,unit=0,drive=drive-ide0-1-0,id=ide0-1-0 -netdev tap,fd=18,id=hostnet0 -device rtl8139,netdev=hostnet0,id=net0,mac=52:54:00:20:0b:dd,bus=pci.0,addr=0x3 -netdev tap,fd=19,id=hostnet1 -device rtl8139,netdev=hostnet1,id=net1,mac=52:54:00:c7:05:c9,bus=pci.0,addr=0x6 -chardev pty,id=charserial0 -device isa-serial,chardev=charserial0,id=serial0 -usb -vnc 127.0.0.1:0 -vga std -device intel-hda,id=sound0,bus=pci.0,addr=0x4 -device hda-duplex,id=sound0-codec0,bus=sound0.0,cad=0 -device virtio-balloon-pci,id=balloon0,bus=pci.0,addr=0x5 + LC_ALL=C PATH=/usr/local/sbin:/usr/local/bin:/usr/bin:/usr/sbin:/sbin:/bin QEMU_AUDIO_DRV=none /usr/bin/kvm -S -M pc-1.0 -cpu core2duo,+lahf_lm,+popcnt,+sse4.2,+sse4.1,+cx16,-monitor,-vme -enable-kvm -m 1024 -smp 1,sockets=1,cores=1,threads=1 -name win7-32 -uuid 9c5a2a97-7657-add4-2c4a-b9f1f8c076bd -nodefconfig -nodefaults -chardev socket,id=charmonitor,path=/var/lib/libvirt/qemu/win7-32.monitor,server,nowait -mon chardev=charmonitor,id=monitor,mode=control -rtc base=localtime -no-shutdown -drive file=/host/Users/ste/Desktop/KVM/win7-32.img,if=none,id=drive-ide0-0-0,format=raw -device ide-drive,bus=ide.0,unit=0,drive=drive-ide0-0-0,id=ide0-0-0,bootindex=1 -drive if=none,media=cdrom,id=drive-ide0-1-0,readonly=on,format=raw -device ide-drive,bus=ide.1,unit=0,drive=drive-ide0-1-0,id=ide0-1-0 -netdev tap,fd=18,id=hostnet0 -device rtl8139,netdev=hostnet0,id=net0,mac=52:54:00:20:0b:dd,bus=pci.0,addr=0x3 -netdev tap,fd=19,id=hostnet1 -device rtl8139,netdev=hostnet1,id=net1,mac=52:54:00:c7:05:c9,bus=pci.0,addr=0x6 -chardev pty,id=charserial0 -device isa-serial,chardev=charserial0,id=serial0 -usb -vnc 127.0.0.1:0 -vga std -device intel-hda,id=sound0,bus=pci.0,addr=0x4 -device hda-duplex,id=sound0-codec0,bus=sound0.0,cad=0 -device virtio-balloon-pci,id=balloon0,bus=pci.0,addr=0x5 char device redirected to /dev/pts/2 kvm: malloc.c:2451: sYSMALLOc: Assertion `(old_top == (((mbinptr) (((char *) &((av)->bins[((1) - 1) * 2])) - __builtin_offsetof (struct malloc_chunk, fd)))) && old_size == 0) || ((unsigned long) (old_size) >= (unsigned long)((((__builtin_offsetof (struct malloc_chunk, fd_nextsize))+((2 * (sizeof(size_t))) - 1)) & ~((2 * (sizeof(size_t))) - 1))) && ((old_top)->size & 0x1) && ((unsigned long)old_end & pagemask) == 0)' failed. 2014-05-16 08:38:32.952+0000: shutting down And also: *** glibc detected *** /usr/bin/kvm: double free or corruption (fasttop): 0x00007f6530001c40 *** ProblemType: Bug DistroRelease: Ubuntu 12.04 Package: qemu-kvm 1.0+noroms-0ubuntu14.14 ProcVersionSignature: Ubuntu 3.2.0-61.93-generic 3.2.55 Uname: Linux 3.2.0-61-generic x86_64 ApportVersion: 2.0.1-0ubuntu17.6 Architecture: amd64 Date: Fri May 16 10:40:47 2014 KvmCmdLine: Error: command ['ps', '-C', 'kvm', '-F'] failed with exit code 1: UID PID PPID C SZ RSS PSR STIME TTY TIME CMD MachineType: Hewlett-Packard HP ProBook 4520s MarkForUpload: True ProcEnviron: - TERM=xterm - PATH=(custom, no user) - LANG=en_US.UTF-8 - SHELL=/bin/bash + TERM=xterm + PATH=(custom, no user) + LANG=en_US.UTF-8 + SHELL=/bin/bash ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-3.2.0-61-generic root=UUID=D2E20BC3E20BAAB5 loop=/hostname/disks/root.disk ro quiet splash vt.handoff=7 SourcePackage: qemu-kvm UpgradeStatus: No upgrade log present (probably fresh install) dmi.bios.date: 08/26/2010 dmi.bios.vendor: Hewlett-Packard dmi.bios.version: 68AZZ Ver.
