Description CongLi 2014-03-08 20:52:49 EST

Description of problem:
qemu core dump when install a RHEL.7 guest(xhci) with migration

Version-Release number of selected component (if applicable):
kernel-3.10.0-99.el7.x86_64
qemu-kvm-rhev-1.5.3-52.el7.x86_64

How reproducible:
always

Steps to Reproduce:
1. Install a RHEL.7 guest with xhci device
    -device nec-usb-xhci,id=usb1,bus=pci.0,addr=03 \
    -drive id=drive_image1,if=none,cache=none,snapshot=off,aio=native,file=/home/staf-kvm-devel/autotest-devel/client/tests/virt/shared/data/images/RHEL-Server-7.0-64-virtio.qcow2 \
    -device virtio-blk-pci,id=image1,drive=drive_image1,bootindex=1,bus=pci.0,addr=04 \
    -device virtio-net-pci,mac=9a:cd:ce:cf:d0:d1,id=idRrA4Ny,netdev=idVQ8RcV,bus=pci.0,addr=05  \

2. Keep ping-pong migration during installation 
    -incoming tcp:0:5200
    (qemu) migrate -d tcp:0:5200

3. 

Actual results:
qemu core dump during installation w/ ping-pong migration

Expected results:
guest installation successful w/o any error

Addtional info
1.I can not reproduce this bug use manual test, use auto script( repeadly ping-pong migration while guest installation) can hit .


According to above test ,this bug has not fixed.

Comment 13 Gerd Hoffmann 2014-10-27 05:45:28 EDT

Please retest with qemu-kvm-1.5.3-76.el7 or newer.

Comment 16 Gerd Hoffmann 2014-11-05 09:30:36 EST

Hmm, doesn't reproduce.

Do you hit it on the first migration?
Or is it a bit random?

Could you upload a coredump?
As this seems to be autotest, can you upload the autotest logs too?

Not first migration, the script is ping/pong migration repeadly. Not easy reproduce for manual test

Test on AMD machine, work well.
# uname -r
3.10.0-210.el7.x86_64
# rpm -q qemu-kvm
qemu-kvm-1.5.3-83.el7.x86_64

Tried windows guest , will hit another issue,not hit core dump.
