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.

How reproducible:
100%

Steps to Reproduce:

In terminal 1:
/usr/libexec/qemu-kvm -m 1024 -spice port=3001,disable-ticketing,addr=127.0.0.1,seamless-migration=on -vga qxl /home/images/rhel67.img -monitor stdio -device intel-hda -device hda-duplex -chardev spicevmc,server,host=127.0.0.1,name=smartcard,id=ccid -device usb-ccid -device ccid-card-passthru,chardev=ccid -usb

In terminal 2:
/usr/libexec/qemu-kvm -m 1024 -spice port=3002,disable-ticketing,addr=127.0.0.1,seamless-migration=on -vga qxl /home/images/rhel67.img -monitor stdio -incoming tcp:127.0.0.1:4444 -device intel-hda -device hda-duplex -chardev spicevmc,server,host=127.0.0.1,name=smartcard,id=ccid -device usb-ccid -device ccid-card-passthru,chardev=ccid -usb

In terminal 3:
remote-viewer spice://127.0.0.1?port=3001

Start about a 4-5 min video (Music video, primarily tested) on guest.

In terminal 1:
(qemu) client_migrate_info spice 127.0.0.1 3002
(qemu) migrate -d tcp:127.0.0.1:4444
(qemu) info migrate

Actual results:
Video stalls migration until video is stopped.

Expected results:
Video should migrate during video

Bill, have you tried setting migrate_set_speed to something higher than default? Migration can appear to be stalled and time out when dirty pages occur faster, than they are transferred (which can occur during video playback

Comment 8 Bill Sanford 2015-10-27 14:39:38 UTC
I still see it happening in the 7.2 host.

Comment 9 Jonathon Jongsma 2016-02-19 21:11:32 UTC
