[CentOS] Perhaps trivial problem but important to me

2023-01-17 Thread jefflpost
I have two computers: CentOS 7 (KDE 4) and CentOS 8 (KDE 5). I'm also
an avid Doom player (yeah, I'm an old geezer). On C7 using prboom v
2.5.0 and a graphical interface I wrote to select a wad file to play
without using the command line, everything works fine. On C8, using
the same prboom 2.5.0, graphical interface, and the same SDL
libraries, the video is "jerky" - every 2 seconds or so the video
stops for a fraction of a second and then restarts. This makes game
play a bit irritating.

This problem does not occur when playing videos with mplayer, also
using a graphical interface I wrote to select files to play.

I've looked at system settings, checked process usage using ps and can
find no reason why there is a difference between playing Doom in C7
and C8.

Any suggestions will be greatly appreciated.

Jeff

   Does the same happen when using the ISO file directly as location
   argument?

Then I get immediately after the "dracut initqueue hook" message
the losetup error because I'm not root.

Hi,

I've loop-mounted the latest CentOS Stream 9 DVD ISO and try to do
a virt-install (2.0.x for some reason) as non-root user (libvirt
group member) using --location with the mount path, but then I
come across the problem decribed here:

   https://bugzilla.redhat.com/show_bug.cgi?id=2022630

That is, I see on the console "Starting dracut initqueue hook...",
then it stalls for a while, and then I get all the timeouts
described in the bug report.

Any suggestions for a workaround (with virt-install 2.0.x and
as non-root user)?

Background:
Dor some reason I need to use virt-install 2.0.x as non-root to
install CentOS Stream 9.  The "normal" way, specifying a URL
with --location, does not work because it fails with permission
denied for losetup.  It looks like virt-install 3.2.x does not
have this problem anymore.
