Fix included in qemu-kvm-rhev-2.9.0-16.el7_4.15 I have tried this scenario on the qemu-kvm-rhev-2.9.0-16.el7_4.15.ppc64le, the result is pass. version: host: 3.10.0-861.el7.ppc64le qemu-kvm-rhev-2.9.0-16.el7_4.15.ppc64le SLOF-20170724-2.git89f519f.el7.noarch guest: 3.10.0-861.el7.ppc64le Steps to Reproduce: 1.Boot a guest on src host, there are two scsi disks that with dataplane: /usr/libexec/qemu-kvm -nodefaults -object iothread,id=iothread0 -device virtio-scsi-pci,bus=pci.0,addr=0x1f,id=scsi0,iothread=iothread0 -drive file=/home/xianwang/rhel75-ppc64le-virtio-scsi.qcow2,media=disk,if=none,cache=none,id=drive_sysdisk,aio=native,format=qcow2,werror=stop,rerror=stop -device scsi-hd,drive=drive_sysdisk,bus=scsi0.0,id=sysdisk,bootindex=0 -drive file=/home/xianwang/r1.qcow2,if=none,cache=none,id=drive_ddisk_2,aio=native,format=qcow2,werror=stop,rerror=stop -device scsi-hd,drive=drive_ddisk_2,bus=scsi0.0,id=ddisk_2 -monitor stdio -vga std -vnc :1 -m 4096 -chardev socket,id=console0,path=/tmp/console0,server,nowait -device spapr-vty,chardev=console0 2.on dst host, boot a guest with the same qemu cli with src, appending -incoming tcp:0:5801 3.on src host, do migration (qemu) migrate -d tcp:10.66.10.208:5801 Actual results: Migration completed and vm works well on destination host src: (qemu) info migrate Migration status: completed dst: (qemu) info status VM status: running |
