Package: qemu-kvm Version: 1:2.1+dfsg-12+deb8u6 Severity: critical Justification: breaks the whole system
Dear Maintainer, Over the course of the past few weeks, a guest KVM instance that relies on USB pass through has been found in the powered off state. Restarting it shows that it has been hard powered off. This is now reproducible with the connected RFXCom hardware. Guest OS = Debian Jessie Host OS = Debian Jessie Start guest machine, and configure USB pass through. In this case, it's for an RFXCom USB radio transceiver. Device is correctly detected in the guest, and shows up as expected in lsusb. Start software that accesses the device. In this case, Domoticz home automation software. Within a few minutes, the machine will be hard powered off. The following logs are present on the host. 2017-01-01 23:40:27.179+0000: starting up LC_ALL=C PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin QEMU_AUDIO_DRV=spice /usr/bin/kvm -name homeauto -S -machine pc-i440fx-2.1,accel=kvm,usb=off -m 6144 -realtime mlock=off -smp 2,sockets=2,cores=1,threads=1 -uuid a79858f4-274e-425f-aece-98c14dc8fbc6 -no-user-config -nodefaults -chardev socket,id=charmonitor,path=/var/lib/libvirt/qemu/homeauto.monitor,server,nowait -mon chardev=charmonitor,id=monitor,mode=control -rtc base=utc,driftfix=slew -global kvm-pit.lost_tick_policy=discard -no-hpet -no-shutdown -global PIIX4_PM.disable_s3=1 -global PIIX4_PM.disable_s4=1 -boot strict=on -device piix3-usb-uhci,id=usb,bus=pci.0,addr=0x1.0x2 -device virtio-serial-pci,id=virtio-serial0,bus=pci.0,addr=0x6 -drive file=/media/store/KVM_VMs/homeauto-new.qcow2,if=none,id=drive-virtio-disk0,format=qcow2 -device virtio-blk-pci,scsi=off,bus=pci.0,addr=0x7,drive=drive-virtio-disk0,id=virtio-disk0,bootindex=1 -drive file=/media/store/KVM_VMs/homeauto-new-1.qcow2,if=none,id=drive-virti o-disk1,format=qcow2 -device virtio-blk-pci,scsi=off,bus=pci.0,addr=0x9,drive=drive-virtio-disk1,id=virtio-disk1 -drive file=/media/store/KVM_VMs/homeauto-new-3.qcow2,if=none,id=drive-virtio-disk2,format=qcow2 -device virtio-blk-pci,scsi=off,bus=pci.0,addr=0xa,drive=drive-virtio-disk2,id=virtio-disk2 -netdev tap,fd=28,id=hostnet0,vhost=on,vhostfd=29 -device virtio-net-pci,netdev=hostnet0,id=net0,mac=52:54:00:38:01:2d,bus=pci.0,addr=0x3 -chardev pty,id=charserial0 -device isa-serial,chardev=charserial0,id=serial0 -chardev spicevmc,id=charchannel0,name=vdagent -device virtserialport,bus=virtio-serial0.0,nr=1,chardev=charchannel0,id=channel0,name=com.redhat.spice.0 -device usb-tablet,id=input0 -spice port=5904,addr=127.0.0.1,disable-ticketing,seamless-migration=on -device qxl-vga,id=video0,ram_size=67108864,vram_size=67108864,bus=pci.0,addr=0x2 -device intel-hda,id=sound0,bus=pci.0,addr=0x4 -device hda-duplex,id=sound0-codec0,bus=sound0.0,cad=0 -chardev spicevmc,id=charredir0,name=usbr edir -device usb-redir,chardev=charredir0,id=redir0 -chardev spicevmc,id=charredir1,name=usbredir -device usb-redir,chardev=charredir1,id=redir1 -chardev spicevmc,id=charredir2,name=usbredir -device usb-redir,chardev=charredir2,id=redir2 -chardev spicevmc,id=charredir3,name=usbredir -device usb-redir,chardev=charredir3,id=redir3 -device usb-host,hostbus=6,hostaddr=4,id=hostdev0 -device virtio-balloon-pci,id=balloon0,bus=pci.0,addr=0x8 -msg timestamp=on char device redirected to /dev/pts/1 (label charserial0) main_channel_link: add main channel client main_channel_handle_parsed: net test: latency 2.497000 ms, bitrate 41698055 bps (39.766364 Mbps) red_dispatcher_set_cursor_peer: inputs_connect: inputs channel client create === Normal behaviour until Domoticz is started... === qemu-system-x86_64: /build/qemu-XXUWBP/qemu-2.1+dfsg/hw/usb/core.c:600: usb_packet_copy: Assertion `p->actual_length + bytes <= iov->size' failed. 2017-01-01 23:42:30.995+0000: shutting down I have tried 2.7+dfsg-3~bpo8+2 from jessie-backports, but the behaviour is the same.
