Kevin, could storage migration interfere with the patches you committed recently that affect caching with BDRV_O_INCOMING? Either by making things better, or by making them much worse. Would it make any sense for writes to clear BDRV_O_INCOMING? Is this still reproducible with the latest packages? Looks like a potential duplicate of bug 1048575.

Hi Sluo, Could you have a try and update testing result in the bz? Best Regards, Junyi Retried it on the latest qemu-kvm and kernel version with the same steps as comment #0. I tried 3 times storage vm migration with nbd which all copy image from src to dest successfully without any core dumped. So I think this issue has gone correctly. host info: # uname -r && rpm -q qemu-kvm-rhev 3.10.0-115.el7.x86_64 qemu-kvm-rhev-1.5.3-59.el7ev.x86_64 guest info: # uname -r 3.10.0-115.el7.x86_64 - dest: {"execute":"qmp_capabilities"} {"return": {}} { "execute": "nbd-server-start", "arguments": { "addr": { "type": "inet", "data": { "host": "10.66.8.202","port":"7777"}}}} {"return": {}} {"timestamp": {"seconds": 1396408939, "microseconds": 164689}, "event": "RESUME"} <-------------Resume successfully. - sorc: {"execute":"qmp_capabilities"} {"return": {}} { "execute": "drive-mirror", "arguments": { "device": "drive-data-disk", "target": "nbd://10.66.8.202:7777/drive-data-disk", "sync": "full", "format": "raw", "mode": "existing" } } {"timestamp": {"seconds": 1396408402, "microseconds": 708874}, "event": "BLOCK_JOB_READY", "data": {"device": "drive-data-disk", "len": 10737418240, "offset": 10737418240, "speed": 0, "type": "mirror"}} {"return": {}} {"timestamp": {"seconds": 1396408406, "microseconds": 532662}, "event": "NIC_RX_FILTER_CHANGED", "data": {"name": "virtio-net-pci0", "path": "/machine/peripheral/virtio-net-pci0/virtio-backend"}} { "execute": "drive-mirror", "arguments": { "device": "drive-system-disk", "target": "nbd://10.66.8.202:7777/drive-system-disk", "sync": "full", "format": "raw", "mode": "existing" } } {"return": {}} {"timestamp": {"seconds": 1396408890, "microseconds": 899804}, "event": "BLOCK_JOB_READY", "data": {"device": "drive-system-disk", "len": 21474836480, "offset": 21474836480, "speed": 0, "type": "mirror"}} {"execute": "migrate","arguments":{"uri": "tcp:10.66.8.202:5888"}} {"return": {}} {"timestamp": {"seconds": 1396408939, "microseconds": 65155}, "event": "STOP"} {"timestamp": {"seconds": 1396408939, "microseconds": 70076}, "event": "SPICE_MIGRATE_COMPLETED"} {"timestamp": {"seconds": 1396408941, "microseconds": 143644}, "event": "SHUTDOWN"} {"timestamp": {"seconds": 1396408941, "microseconds": 144028}, "event": "BLOCK_JOB_COMPLETED", "data": {"device": "drive-system-disk", "len": 21474836480, "offset": 21474836480, "speed": 0, "type": "mirror"}} {"timestamp": {"seconds": 1396408941, "microseconds": 145512}, "event": "BLOCK_JOB_COMPLETED", "data": {"device": "drive-data-disk", "len": 10737418240, "offset": 10737418240, "speed": 0, "type": "mirror"}} {"timestamp": {"seconds": 1396408941, "microseconds": 146769}, "event": "DEVICE_TRAY_MOVED", "data": {"device": "ide1-cd0", "tray-open": true}} {"timestamp": {"seconds": 1396408941, "microseconds": 146849}, "event": "DEVICE_TRAY_MOVED", "data": {"device": "floppy0", "tray-open": true}} Best Regards, sluo *** This bug has been marked as a duplicate of bug 1048575 *** |
