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.

Screen cast while xfer files

Description of problem:
The purpose of file xfer progress bar is to show how much data were already transmitted from client to guest. Progress of the bar should always have increasing tendency - no data are erased from the guest while transferring files. Nevertheless I found it does not behave correctly when xfer multiple, relatively bigger, files of different size. Progress of the bar in this case is not smooth and sometimes drops to lower value.

Version-Release number of selected component (if applicable):
client (rhel7.4):
spice-gtk3-0.33-3.el7.x86_64

guest (rhel7.4):
spice-vdagent-0.14.0-14.el7.x86_64
also reproducible on Win guests



How reproducible:
almost always - depends on how much differs files in size. Not reproducible with files of the same size

Steps to Reproduce:
1. drag&drop several files of different size from client to guest (recommended size in range (1MB to ~500MB) to have most vivid result)
2.
3.

Actual results:
Progress of the bar is jerky and sometimes drops to the lower values (are we erasing something back?). See attached screen cast.

Expected results:
Progress is smooth and have only increasing tendency.

Could you please check if this is a regression from 7.3?

Proposed fix: https://www.redhat.com/archives/virt-tools-list/2017-May/msg00052.html

Yes I remember there are more progress bars - each for one transferred file back in rhel7.3, so it must be a regression.

I can reproduce it with virt-viewer-5.0-2.el7.x86_64.

then i verified it with virt-viewer-5.0-4.el7.x86_64, the progress bar is smooth now.

so move the bug from ON_QA to VERIFIED.
