Guest desktop when it freezes.
Hi Qunfang, You said 'Randomly, I hit it twice today.' about how many times had you migrated ? (i.e. is it it 2 in 10 or 2 in 100 ?)

Hi, David I could not tell an exact number about the migration time now. But usually when I hit such issue in migration, I will try it for about 10~20 round ping-pong migration. It should not reach to 50 or 100 times because testing it manually for so many times will spend too much time and will block my further test process. Thanks, Qunfang I hit the same issue with the versions: qemu-kvm-2.6.0-16.el7.x86_64 kernel-3.10.0-481.el7.x86_64 How reproducible: I hit it many times today. Steps to Reproduce: 1. Boot a windows guest on src host and start installation. /usr/libexec/qemu-kvm -name win -cpu Westmere,check -m 2048 -realtime mlock=off -smp 4,sockets=2,cores=2,threads=1 -uuid 7bef3814-631a-48bb-bae8-2b1de75f7a13 -nodefaults -monitor stdio -rtc base=localtime,driftfix=slew -global kvm-pit.lost_tick_policy=discard -global PIIX4_PM.disable_s3=1 -global PIIX4_PM.disable_s4=1 -boot order=c,menu=on -device virtio-serial-pci,id=virtio-serial0,bus=pci.0,addr=0x6 -drive file=/mnt/nfs/win10x64.iso,if=none,media=cdrom,id=drive-virtio-win0,readonly=on,format=raw -device ide-drive,drive=drive-virtio-win0,id=virtio-win0 -drive file=/mnt/nfs/virtio-win.iso,if=none,media=cdrom,id=drive-virtio-win1,readonly=on,format=raw -device ide-drive,drive=drive-virtio-win1,id=virtio-win1 -drive file=/mnt/nfs/winsys.qcow2,if=none,id=drive-virtio-blk0,format=qcow2,werror=stop,rerror=stop -device virtio-scsi-pci,id=virtio-blk0,disable-legacy=true,disable-modern=false -device scsi-disk,drive=drive-virtio-blk0,scsi-id=0,lun=0 -device virtio-balloon-pci,id=balloon0,bus=pci.0,addr=0x8 -msg timestamp=on -spice port=5930,disable-ticketing -vga qxl -global qxl-vga.vram_size=33554432 -device qxl,id=video1,vram_size=67108864,bus=pci.0,addr=0x4 -netdev tap,id=hostnet0,vhost=on -device virtio-net-pci,netdev=hostnet0,id=net0,mac=3C:D9:2B:09:AB:44,bus=pci.0,addr=0x7 -qmp tcp:0:5555,server,nowait -boot order=d 2. Boot the guest on destination host with "-incoming x-rdma:0:5800" 3. Migrate the guest during installation.

That's win10 so a lot newer than this old bug; so I suggest it might be better with a new bug for that. It's also possibly related to 1357765. Are you sure you were using x-rdma? I think x-rdma only works on older qemu and you say you're using newer 2.6.0 qemu. oops, wrong needinfo. I am sorry for my carelessness .In fact ,I set up the VM with "-incoming tcp:0:5800". OK,I will file new bug for this. As comment 15 it seems to work now; not quite sure which fix helped; possibly the set related to bz 1357765 |
