Fix included in qemu-kvm-1.5.3-105.el7_2.9
Reproduce this bug using the following version: kernel-3.10.0-510.el7.x86_64 qemu-kvm-1.5.3-105.el7_2.8.x86_64 Reproduce steps: 1. create a 4M lv # pvcreate /dev/sdg # vgcreate testvg /dev/sdg # lvcreate -L 4M -T testvg/testlv # lvs LV VG Attr LSize Pool Origin Data% Meta% Move Log Cpy%Sync Convert home rhel_hp-dl380pg8-09 -wi-ao---- 212.61g root rhel_hp-dl380pg8-09 -wi-ao---- 50.00g swap rhel_hp-dl380pg8-09 -wi-ao---- 15.75g testlv testvg twi-a-tz-- 4.00m 0.00 0.88 2. create a data disk image based on the above lv # qemu-img create -f qcow2 /dev/testvg/testlv 10G 3. boot a rhel7.3 guest with the above data disk image # /usr/libexec/qemu-kvm \ -S \ -name 'rhel7.3' \ -machine pc \ -m 4096 \ -smp 4,maxcpus=4,sockets=1,cores=4,threads=1 \ -cpu SandyBridge \ -rtc base=localtime,clock=host,driftfix=slew \ -nodefaults \ -boot menu=on \ -enable-kvm \ -monitor stdio \ -drive file=/mnt/rhel7.3.raw,format=raw,id=drive_sysdisk,if=none,cache=none,aio=native,werror=stop,rerror=stop \ -device virtio-blk-pci,scsi=off,bus=pci.0,addr=0x8,drive=drive_sysdisk,bootindex=1 \ -drive if=none,cache=none,format=qcow2,file=/dev/testvg/testlv,werror=stop,id=drive-virtio-disk0 \ -device virtio-blk-pci,scsi=off,bus=pci.0,addr=0x9,drive=drive-virtio-disk0,id=virtio-disk0 \ -vga qxl \ -spice port=5900,disable-ticketing 4. on the same host, use the same command line with "-incoming tcp:0:5800", boot the rhel7.3 guest 5. inside guest # dd if=/dev/zero of=/dev/vdb oflag=direct bs=4k 6. after guest is paused with io-error, do migration (qemu) info status VM status: paused (io-error) (qemu) migrate -d tcp:0:5800 7. on host, grow the logical volume by 4 MB # lvresize -L +4M /dev/testvg/testlv 8. in destination, resume the guest (qemu)c after step8, "Virtqueue size exceeded" error from destination QEMU and qemu-kvm quits. Verify this bug using the following version: kernel-3.10.0-510.el7.x86_64 qemu-kvm-1.5.3-105.el7_2.9.x86_64 Do the above test, after step 8, destination qemu-kvm did not quit and guest can resume normally.
