Bug 720237

reproduce on qemu-kvm-0.12.1.2-2.172.el6.x86_64
verify on qemu-kvm-0.12.1.2-2.192.el6.x86_64

steps to reproduce:
1.boot guest from src host
 /usr/libexec/qemu-kvm -m 4G -smp 4 -M rhel6.1.0 -drive file=rhel62-guest.raw,if=none,id=drive-virtio0-0-0,format=raw,werror=ignore,rerror=ignore,cache=none,aio=native,aio=native -device virtio-blk-pci,drive=drive-virtio0-0-0,id=virti0-0-0,bootindex=1 -uuid 9e6f04cf-2ad7-45aa-9333-2d2ee26570c6 -monitor stdio -device usb-ehci,id=ehci  -drive file=usb-storage.qcow2,if=none,id=drive-usb-0-0,media=disk,format=qcow2,cache=none,werror=stop,rerror=stop,aio=native -device usb-storage,drive=drive-usb-0-0,id=usb-0-0,bus=ehci.0,port=1

2.boot guest from des host
/usr/libexec/qemu-kvm -m 4G -smp 4 -M rhel6.1.0 -drive file=rhel62-guest.raw,if=none,id=drive-virtio0-0-0,format=raw,werror=ignore,rerror=ignore,cache=none,aio=native,aio=native -device virtio-blk-pci,drive=drive-virtio0-0-0,id=virti0-0-0,bootindex=1 -uuid 9e6f04cf-2ad7-45aa-9333-2d2ee26570c6 -monitor stdio -device usb-ehci,id=ehci  -drive file=usb-storage.qcow2,if=none,id=drive-usb-0-0,media=disk,format=qcow2,cache=none,werror=stop,rerror=stop,aio=native -device usb-storage,drive=drive-usb-0-0,id=usb-0-0,bus=ehci.0,port=1 -incoming tcp:0:5555

3. migrate -d tcp:xxxx:5555

actual result:
1)qemu-kvm-0.12.1.2-2.172.el6.x86_64
 migration is successful.

2)qemu-kvm-0.12.1.2-2.192.el6.x86_64
  migration fail
(qemu) migrate -d tcp:10.66.9.97:5555
state blocked by non-migratable device '0000:00:05.0/ehci'

base on above testing result, this bug has been fixed.

Hi Gerd,
    I am testing on RHEV-6.7 and i tried the same step as #comment6, but there is no waring like "state blocked by non-migratable device '0000:00:05.0/ehci'" ,the migration will be complete.

host info:

qemu-kvm-rhev-0.12.1.2-2.469.el6.x86_64
kernel-2.6.32-555.el6.x86_64

step:
1) boot in src host:

    -nodefaults \
    -vga qxl \
    -chardev socket,id=qmp_id_qmpmonitor1,path=/tmp/monitor-qmp,server,nowait \

    -device isa-serial,chardev=serial_id_serial0 \
    -chardev socket,id=seabioslog,path=/tmp/seabios-2014-12-02,server,nowait \
    -device virtio-net-pci,mac=fa:f7:f8:5f:f2:52,id=idn0VnaA,vectors=4,netdev=id8xJhp7,bus=pci.0 \

    -drive file=/mnt/u1.qcow2,if=none,id=drive-usb-0-1,media=disk,format=qcow2,cache=none,aio=native \


2)boot in dst host:

/usr/libexec/qemu-kvm \
    -M rhel6.1.0 \
    -nodefaults \
    -vga qxl \
    -chardev socket,id=qmp_id_qmpmonitor1,path=/tmp/monitor-qmp,server,nowait \
    -mon chardev=qmp_id_qmpmonitor1,mode=control \
    -chardev socket,id=serial_id_serial0,path=/tmp/serial-serial,server,nowait \
    -device isa-serial,chardev=serial_id_serial0 \
    -chardev socket,id=seabioslog,path=/tmp/seabios-2014-12-02,server,nowait \
    -device virtio-net-pci,mac=fa:f7:f8:5f:f2:52,id=idn0VnaA,vectors=4,netdev=id8xJhp7,bus=pci.0 \
    -netdev tap,ifname=tap1,id=id8xJhp7,vhost=on \
    -m 8192 \
    -smp 8,maxcpus=10 \
    -cpu 'SandyBridge' \
    -boot menu=on \
    -enable-kvm \
    -spice port=8000,disable-ticketing \
    -drive id=drive_image1,if=none,cache=none,aio=native,file=/mnt/RHEL-Server-6.7-32-virtio.raw \
    -device ide-drive,id=image1,drive=drive_image1,bus=ide.0,unit=0 \
    -monitor stdio \
    -device usb-ehci,id=ehci \
    -device usb-storage,drive=drive-usb-0-1,id=usb-0-1,removable=on,bus=ehci.0,port=1 \
    -drive file=/mnt/u1.qcow2,if=none,id=drive-usb-0-1,media=disk,format=qcow2,cache=none,aio=native \
    -incoming "tcp:0:5800" \



3)migrate -d tcp:xxxx:5800

4)actual result:

migration is successfull.

5)expected result:

migration fails for "

state blocked by non-migratable device '0000:00:05.0/ehci "

6) from the result that ,the case fails so i want to ask if this is a regression bug or not ,if it is ,should i open a new bug ?

That'll only happen with the RHEL-6.1 qemu-kvm version,
not 6.2+ with -M rhel6.1.0
