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.
Description of problem:
To copy a large file from src host to guest during live migration , file transferring is terminated when migration finishes.
Version-Release number of selected component (if applicable):
kernel-3.10.0-481.el7.x86_64
qemu-kvm-rhev-2.6.0-21.el7.x86_64
How reproducible:
4/4
Steps to Reproduce:
1.Start VM in src host(rhel7.3):
/usr/libexec/qemu-kvm -name win -cpu Westmere,check -m 2048 -realtime mlock=off -smp 4,sockets=2,cores=2,threads=1 -uuid 7bef3814-631a-48bb-bae8-2b1de75f7a13 -nodefaults -monitor stdio -rtc base=localtime,driftfix=slew -drive file=/mnt/nfs/RHEL-Server-7.3-64-virtio-scsi.qcow2,if=none,id=drive-virtio-blk0,format=qcow2,werror=stop,rerror=stop,cache=none -device virtio-scsi-pci,id=virtio-blk0 -device scsi-disk,drive=drive-virtio-blk0,bootindex=0,scsi-id=0,lun=0 -device virtio-balloon-pci,id=balloon0,bus=pci.0,addr=0x8 -msg timestamp=on -spice port=5930,disable-ticketing -vga qxl -global qxl-vga.vram_size=33554432 -device qxl,id=video1,vram_size=67108864,bus=pci.0,addr=0x4 -netdev tap,id=hostnet0,vhost=on -device virtio-net-pci,netdev=hostnet0,id=net0,mac=3C:D9:2B:09:AB:44,bus=pci.0,addr=0x7
2. Start listening mode in des host with "-incoming tcp:0:1234"
3. Copy a large file from host to guest in src host:
# scp $filename root@$src_guest_ip:/root/
4. Start live migration
Actual results:
The file transferring is terminated after the guest is migrated completely.
Expected results:
The file keeps transferring after migration finishes.
Additional info:
1.The file transferring is terminated:
"***.qcow2 42% 3389MB 0.0KB/s - stalled -Write failed: Broken pipe" in the file transferring terminal.
2.This issue exists on qemu-kvm-rhev-2.3.0-6.el7.x86_64.
