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.

VDSM Version:vdsm-4.40.11-1.el8ev
SPICE Version:0.14.2 - 1.el8

How reproducible:
always


Steps to Reproduce:
1. Run VM
2. Connect to it with remote-viewer
3. Open 3. or 4. display (View->Displays)
4. Try to mouse interact on 3. or 4. display (for example right click to show context menu)

Actual results:
nothing happens

Expected results:
Relevant display show graphics according to mouse interaction.

Additional info:
I cannot reproduce this with 2. display (or first one). I tried 2 RHEL 8.2 VMs with the same result.

This is regression - not reproducible with rhel8.1 guest VM.

Something is off in the client if on resend monitors_config it doesn't send for 4 displays.
Journal logs aren't helpful here, host logs with spice debug enabled could point out some issue there.
Could you also try reproduce connecting to RHEL 7 host with this RHEL 8 client?

spice-server G_MESSAGES_DEBUG=all log (rhel82 guest)

I connected to VM and opened 3. dispay - no mouse interaction there. I suspect it is https://bugzilla.redhat.com/show_bug.cgi?id=1790904, but now mouse interaction can not be seen at all.
Comment 5 Radek Duda 2020-05-06 11:46:15 UTC 
Forgot to add. Testing configuration for above log:

client rhel8.2:
virt-viewer-7.0-9.el8.x86_64
spice-gtk3-0.37-1.el8.x86_64

guest rhel8.2:
spice-vdagent-0.19.0-3.el8.x86_64
mesa-dri-drivers-19.3.4-2.el8.x86_64
xorg-x11-drv-qxl-0.1.5-11.el8.x86_64

host rhel8.2:
spice-server-0.14.2-1.el8.x86_64
qemu-kvm-4.2.0-19.module+el8.2.0+6296+6b821950.x86_64
vdsm-4.40.13-1.el8ev.x86_64


This is not reproducible always. Sometimes remote-viewer hangs after closing it with grey canvas stating 'Connecting to graphic server'.

Start RHEL81 VM
Connect with remote-viewer
Open 3. display
try to interact (righ mouse click)

context menu appears - this is ok
Comment 7 Julien Ropé 2020-05-06 12:53:02 UTC 
I have reproduced it here.

From my observations: If you log into the VM using the Xorg server (from the login screen, choose "Standard on Xorg"), the problem disapear.

As you mentioned above, I think it is similar to https://bugzilla.redhat.com/show_bug.cgi?id=1790904 : Under Wayland, the Spice vdagent process is unable to properly match SPICE display IDs to XWayland IDs. The agent is then "guessing", but it requires the IDs to be consecutive, otherwise they don't match.
Then if you open display #3 and #4 without opening #2, the Ids are messed up for the agent, and it can't properly use the mouse coordinates.
Comment 9 Julien Ropé 2020-11-19 14:47:36 UTC 
Provided a fix for this with the following commits: https://gitlab.freedesktop.org/spice/linux/vd_agent/-/merge_requests/28
