When this error occurs, qemu-monitor shows the guest has stopped. The error did not occur immediately, but at the point that the boot, running from an attached Ubuntu 14.04.1 iso, switched to graphical mode after text-mode startup. + +The root-cause was verified by switching only the ide-hd disk to raw format (no OS installed), which allowed the guest to boot normally from the iso. The error and fix are reliably repeatable. + +The interesting part is that the ide-hd (with no OS installed) with qcow2 format was not actually being used for boot - the boot was from a Ubuntu iso, with the intention of installing an ubuntu guest on the attached ide-hd device. The guest was using a vfio-pci passthrough GPU connected to an external UHD monitor. + +The commands used to create the disk images: +qemu-img create -f qcow2 /media/v2min/Data/VMachines-KVM/KVM-NVidia/kvm-nvidia.img 20G +qemu-img create -f raw /media/v2min/Data/VMachines-KVM/KVM-NVidia/kvm-nvidia.img 20G + +The script vm1 was used to launch the guests with "sudo ./vm1", with the only difference between launches being the ide-hd format (raw vs qcow2). With qcow2 this resulted in the terminal below. The corresponding dmesg snippets are attached. There were two dmesg entries each time the error occurred. + +The same problem occurred when using the latest packages from the ppa:jacob/virtualisation. However, when using jacob's packages, it was not verified that raw format resolves the error (I am running this on my primary system and purged jacob's ppa when this problem first occured). + +A fix would be helpful as the qcow2 format allows snapshots, while raw does not. + +----------------------------------System info----------------------------------------------------------- +Linux v2min 3.18.9-031809-generic #201503080036 SMP Sun Mar 8 00:37:46 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux + +/var/log/libvirt/libvirt.d is 0 bytes + +Libvirt versions are these: + +v2min@v2min:~/QCOW2-Error$ dpkg -l | grep libvirt +ii libvirt-bin 1.2.2-0ubuntu13.1.9 amd64 programs for the libvirt library +rc libvirt-glib-1.0-0 0.1.6-1ubuntu2 amd64 libvirt glib mainloop integration +ii libvirt0 1.2.2-0ubuntu13.1.9 amd64 library for interfacing with different virtualization systems +ii python-libvirt 1.2.2-0ubuntu2 amd64 libvirt Python bindings + + +v2min@v2min:~/QCOW2-Error$ dpkg -l | grep qemu +ii ipxe-qemu 1.0.0+git-20131111.c3d1e78-2ubuntu1.1 all PXE boot firmware - ROM images for qemu +ii qemu-keymaps 2.0.0+dfsg-2ubuntu1.10 all QEMU keyboard maps +ii qemu-kvm 2.0.0+dfsg-2ubuntu1.10 amd64 QEMU Full virtualization on x86 hardware (transitional package) +ii qemu-system-common 2.0.0+dfsg-2ubuntu1.10 amd64 QEMU full system emulation binaries (common files) +ii qemu-system-x86 2.0.0+dfsg-2ubuntu1.10 amd64 QEMU full system emulation binaries (x86) +ii qemu-utils 2.0.0+dfsg-2ubuntu1.10 amd64 QEMU utilities + +Passthrough GPU: Zotac GT 730 2GB. +Processor: AMD A10-5800K APU +Primary GPU: Radeon R9-290X + + +------------------------------------------vm1 script----------------------------------------------------- +#!/bin/bash + +configfile=/etc/vfio-pci1.cfg + +vfiobind() { + dev="$1" + vendor=$(cat /sys/bus/pci/devices/$dev/vendor) + device=$(cat /sys/bus/pci/devices/$dev/device) + if [ -e /sys/bus/pci/devices/$dev/driver ];
