Comment 1 Qian Guo 2014-11-24 08:07:12 UTC 
Clone the original bug to qemu-kvm-rhev component for rhel7.1
hit it with qemu-kvm-rhev-2.1.2-8.el7.x86_64
Comment 3 Dr. David Alan Gilbert 2014-11-24 11:41:24 UTC 
Please try waiting ~15mins after the migration_cancel command is issued and see whether it eventually cancels (I think the TCP timeouts should happen by then).

It is easy to reproduce this bug on ppc64 build, so set Hardware to Unspecified.

Version-Release number of selected component:
qemu-kvm-rhev-2.1.2-16.el7.ppc64
Comment 10 Shaolong Hu 2015-06-18 09:12:22 UTC 
Verified on qemu-kvm-rhev-2.3.0-2.el7.x86_64:

1. cmd:

/usr/libexec/qemu-kvm -enable-kvm -M pc -smp 4 -m 4G -name rhel6.3-64 -uuid 3f2ea5cd-3d29-48ff-aab2-23df1b6ae213 -drive file=/root/RHEL-Server-7.2-64-virtio.qcow2,cache=none,if=none,rerror=stop,werror=stop,id=drive-virtio-disk0,format=qcow2,aio=native -device virtio-blk-pci,drive=drive-virtio-disk0,id=device-virtio-disk0,bootindex=1 -netdev tap,script=/etc/qemu-ifup,id=netdev0 -device virtio-net-pci,netdev=netdev0,id=device-net0,mac=aa:54:00:11:22:33 -boot order=cd -monitor stdio -usb -device usb-tablet,id=input0 -chardev socket,id=s1,path=/tmp/s1,server,nowait -device isa-serial,chardev=s1 -monitor tcp::1234,server,nowait -vga qxl -global qxl-vga.revision=3 -spice port=5920,disable-ticketing -global PIIX4_PM.disable_s3=0 -global PIIX4_PM.disable_s4=0 -vnc :10 -qmp tcp:0:5555,server,nowait

2. start migration, on des host, drop migration incoming packet with:
iptables -A INPUT -p tcp -d 10.66.84.12 --dport 5556 -j DROP

3. cancel migration on src host, migration cancelled immediately:

(qemu) migrate_cancel 
(qemu) info migrate
capabilities: xbzrle: off rdma-pin-all: off auto-converge: off zero-blocks: off 
Migration status: cancelled
total time: 0 milliseconds
