Description

Command line looks wrong, there is no sound device at all. Error message looks like a intel-hda device (+codec) should be there. (In reply to Gerd Hoffmann from comment #2) > Command line looks wrong, there is no sound device at all. > Error message looks like a intel-hda device (+codec) should be there. Yes, sorry I pasted the command line when I wanted to remove the intel-hda device to check whether the problem was gone. The correct command line to trigger the problem is to append the following parameters based on the cli in comment 0: -device intel-hda,id=sound0,bus=pci.0,addr=0x5 -device hda-duplex,id=sound0-codec0,bus=sound0.0,cad=0 A complete command line: # /usr/libexec/qemu-kvm -cpu SandyBridge -M rhel6.5.0 -enable-kvm -m 4096 -smp 2,sockets=2,cores=1,threads=1 -name rhel7.0-64 -uuid 9a0e67ec-f286-d8e7-0548-0c1c9ec93009 -nodefconfig -nodefaults -monitor stdio -rtc base=utc,clock=host,driftfix=slew -no-kvm-pit-reinjection -no-shutdown -device piix3-usb-uhci,id=usb,bus=pci.0,addr=0x1.0x2 -device virtio-serial-pci,id=virtio-serial0,bus=pci.0,addr=0x7 -device virtio-scsi-pci,id=scsi0,bus=pci.0,addr=0x4 -drive file=gluster://10.66.**.**/gv0//rhel6.5-64-qzhang.qcow2,if=none,id=drive-disk0,format=qcow2,cache=none,id=disk0 -device scsi-hd,drive=drive-disk0,bus=scsi0.0,id=scsi-disk0 -drive file=gluster://10.66.**.**/gv0/boot.iso,if=none,media=cdrom,id=drive-ide0-1-0,readonly=on,format=raw -device scsi-cd,drive=drive-ide0-1-0,bus=scsi0.0,id=scsi-cdrom,bootindex=1 -netdev tap,id=hostnet0,vhost=on -device virtio-net-pci,netdev=hostnet0,id=net0,mac=52:54:00:d5:51:8a,bus=pci.0,addr=0x3 -chardev pty,id=charserial0 -device isa-serial,chardev=charserial0,id=serial0 -chardev socket,id=channel1,path=/tmp/helloworld1,server,nowait -device virtserialport,chardev=channel1,name=port1,bus=virtio-serial0.0,id=port1 -chardev socket,id=channel2,path=/tmp/helloworld2,server,nowait -device virtserialport,chardev=channel2,name=port2,bus=virtio-serial0.0,id=port2 -chardev spicevmc,id=charchannel0,name=vdagent -device virtserialport,bus=virtio-serial0.0,nr=3,chardev=charchannel0,id=channel0,name=com.redhat.spice.0 -device usb-tablet,id=input0 -spice port=5900,disable-ticketing,seamless-migration=on -vga qxl -global qxl-vga.vram_size=67108864 -device intel-hda,id=sound0,bus=pci.0,addr=0x5 -device hda-duplex,id=sound0-codec0,bus=sound0.0,cad=0 -device virtio-balloon-pci,id=balloon0,bus=pci.0,addr=0x6 -drive if=none,id=drive-fdc0-0-0,format=raw,cache=none -global isa-fdc.driveA=drive-fdc0-0-0 -qmp tcp:0:5555,server,nowait -global PIIX4_PM.disable_s3=0 -global PIIX4_PM.disable_s4=0 http://brewweb.devel.redhat.com/brew/taskinfo?taskID=6695036 Need turn off MSI for intel-hda, rhel6 doesn't support that. patches posted. Reproduced this bug on qemu-kvm-1.5.3-21.el7.x86_64 and verified pass on qemu-kvm-1.5.3-24.el7.x86_64. Steps: Same as comment 0. On qemu-kvm-1.5.3-21.el7.x86_64: After migration, on dst host: QEMU 1.5.3 monitor - type 'help' for more information (qemu) qemu: warning: error while loading state for instance 0x0 of device '0000:00:05.0/intel-hda' load of migration failed [root@localhost ~]# On qemu-kvm-1.5.3-24.el7.x86_64: After migration, guest work well on dst host: (1) (qemu) info status VM status: running (2) Check guest network, mouse/keyboard and then shutdown guest, all work as expected.
