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).

Nov10_journal.ctl
adding journalctl from rhel 8.4 , there should be multiple attemps to start vms with different kernels

It is not probably a virt-manager issue. Please attach the vm xml definition and qemu log from /var/log/libvirt/qemu/. Thanks.

Well, there are a bunch of candidates, the most likely
ones are:
(1) kernel
(2) qemu
(3) spice
I'd suggest to start with 8.2, then upgrade components
one by one to 8.3 and see where it breaks ...

list of updated packages
So i have tried updating from 8.2 to 8.3 packages , i have tried kernel *emu* spice* xorg-x11-drv-intel python* and results is that renering was without issue. After that i tried to update rest of the packages and then it broked. I have attached the list of the packages. Any idea which package should i tried downgrade ?
Hi, so this is not a virt-manager issue and based on comment 9 it looks like it's not caused by qemu, spice or kernel as well. This probably points to some xorg related package.
Peter, the list of packages is way too large to guess which would be the source of the issue. I would suggest to try manually updating xorg related packages to.

list of updated packages - broken
Hi, so i have tried to update xorg related packages and still worked. So i have decided to update gnome and lots of other pckgs to be able correctly start graphical-session, around 190pckgs, and after this update rendering is broken. ( I am not sure if all of the 190 pcks were necessary for gnome update). Any idea which pckgs might be related?
