the product is no longer active in Red Hat Bugzilla.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.
Multiple monitors behave rather incosistently.
When conneting to a VM, it by default has a single monitor visible. (just one device enabled in xrandr output). Enabling more monitors changes this, and it's ok. For now.
The problem arises, when a display channel gets closed. The display keeps being reported as connected. Which might still might be considered OK, albeit a little strange. However, resizing one of the open windows causes, the display to be disabled, yet still connected. The display later gets completely disconnected when it gets "turned of" using Display preferences
It just feels inconsistent, either all 4 devices should be permanently "connected", but just disabled (as is the default behaviour in windows clients), or they should be disconnected unless visible.
Also opening a display and then closing it causes, that vdagent remains listed in xrandr's output. -- which forces the display to open, even though previously explictly closed, when vdagent gets restarted -- which happens a lot, because it exits pretty much everytime the display configuration gets changed - bug 872633 (will try to determine, whether it exits with 1, or actually crashes later, and is actually a different bug.
Anyway, would really like to know, how connecting and disconnecting the displays should behave.

A good question, can you please take this discussion to the spice-devel mailinglist, so that all involved parties can read along and chime-in? Note that Fedora-18 has the exact same code, so this is not a RHEL only thing.

Thanks for the feedback, note that this is a generic tracking bug for getting the feature in
place, and that is more or less done now, so this bug is going to be closed soon.
I agree that some of the behavior needs some fine tuning. I believe that the problem
you're describing is currently being discussed in bug 881072. Please join the discussion
there. If you feel that bug 881072 does not cover your problem, please file a new bug to
track your problem.
Thanks & Regards,
Hans
