Note: This bug is displayed in read-only format because the product is no longer active in Red Hat Bugzilla.

RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

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
