Posted patch upstream for review: [PATCH] pcie-root-port: let it has higher migrate priority Peter Fix included in qemu-kvm-rhev-2.10.0-21.el7 ==Verification== Versions: 3.10.0-855.el7.x86_64 qemu-kvm-rhev-2.10.0-21.el7.x86_64 libvirt-3.9.0-13.el7.x86_64 dpdk-17.11-7.el7.x86_64 Steps: Same steps as Description. All 10 migration runs work well, no any error in host and guest. The migration testing results looks like below: ===========Stream Rate: 1Mpps=========== No Stream_Rate Downtime Totaltime Ping_Loss trex_Loss 0 1Mpps 249 15489 581 12321816.0 1 1Mpps 242 14675 281 6190466.0 2 1Mpps 256 14560 282 3971495.0 3 1Mpps 250 15533 282 13343215.0 4 1Mpps 252 15276 282 9351827.0 5 1Mpps 244 15395 280 11437595.0 6 1Mpps 245 14553 281 5710854.0 7 1Mpps 244 15476 281 12295376.0 8 1Mpps 255 15095 282 4554012.0 9 1Mpps 249 14658 282 6444174.0 1. We found ping loss and trex packets loss are high during the whole migration process, however from QE perspective, we think this bug has been fixed, the packets loss should be a new issue, we will file new bugs later to track them. Thanks. Move this bug to 'VERIFIED'. Please feel free add comment or change status if you disagree. Thanks. (In reply to Pei Zhang from comment #7) > 1.
