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:
virt-manager should support to modify 'Heads' value of Video in GUI
Now libvirt, qemu-kvm, spice support max monitor limitation. virt-viewer can only create one display by default. If we want to create more displays, heads value should be modified.
<video>
<model type='qxl' ram='65536' vram='65536' vgamem='16384' heads='4' primary='yes'/>
<alias name='video0'/>
<address type='pci' domain='0x0000' bus='0x00' slot='0x02' function='0x0'/>
</video>
So it's better to adjust the UI of video device to make heads value editable.
Bugs for reference:
Bug 1283202 - RFE: backport max monitor limitation from spice-server upstream
Bug 1283198 - RFE: backport max monitor limitation from Qemu upstream
Bug 1283207 - RFE: implement max_monitor option for qxl video
Version-Release number of selected component (if applicable):
virt-manager-1.4.1-1.el7.noarch
How reproducible:
100%
Steps to Reproduce:
None
Expected results:
Additional info:
There's already an RFE tracking multihead support for virt-manager. I don't think we should make the 'heads' valuable editable until that work is done, since heads > 1 is a config that virt-manager can't properly handle yet. So just duping to that RFE
