in rhel 8.2 it works just fine , vm rendering is done by intel gpu and image is nice. for rhel 8.3 is result same as for rhel 8.4. Created attachment 1729054 [details]
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. Created attachment 1729102 [details]

there are requested files Hi Gerd, do you have any suggestion what we should investigate/test here, so we know which component is appropriate for this issue? Thanks! > Hi Gerd,

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. Created attachment 1754648 [details]
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?
with mesa 19.3.4-2.el8 rendering is ok after update to mesa 20.1.4-1.el8 rendering is broken, same for mesa 20.3.2-1.el8 . Moving on mesa component. mesa-20.3.3-1 is built in brew. Tested with new mesa, no rendering issue occurred. Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA. For information on the advisory (Moderate: userspace graphics, xorg-x11, and mesa security, bug fix, and enhancement update), and where to find the updated files, follow the link below. If the solution does not work for you, open a new bug report. https://access.redhat.com/errata/RHSA-2021:1804 |
