Operating Systems and Porting / Re: [NEWS] Fedora 41 is out!

« Last post by ClassicHasClass on November 19, 2024, 09:14:23 pm »

On my T2 v/AMD graphics, I upgraded to F41 from the terminal in Gnome via the dnf plugin as described on the Fedora website.

After restarting, the screen went blank for more than five minutes, during which time the machine didn't show up on the network. From experience I knew not to restart. I played a game of chicken with myself regarding connecting to the BMC via ethernet, which I won.

Eventually the login manager appeared.

I don't know if this will help anyone else, but it was my experience. 

That's typical and expected. You can tail the log by logging in as root on another VTY. I didn't get a chance to update the Blackbird yet, but I plan to do so no later than the Thanksgiving long weekend.

Not sure why my pics don't post directly, but I can't seem to attach files either.  I get this error.

"The upload folder is full. Please try a smaller file and/or contact an administrator."

My file is well under the limit.

Operating Systems and Porting / Re: Debian 12 status?

It is really sad that so many people are suffering because of the politics in Debian.  It is really bad for people who spent money on the Raptor hardware and it is also really bad for my family, friends, neighbors and many other people who had these political problems forced upon them by the social media set.

all i know is the installer was broken, i'm sure it still is lol

All Fedora versions on sda and sdd as seen in the screen shot fault with initrd.  Since that screen shot was taken I have used Timeshift on sdd to rollback to before the F41 install.  Same results.  I wiped out sda and installed F41 from scratch, same result.  Then I tried to install F40 from scratch on sda.  The results of this endeavor are in this screen shot.

I will try to get system logs later today.

Thanks for the screenshot. Can you enter the shell and inspect the system logs? Is only Fedora 41 initrd affected and F-40 would boot OK ? Is there a significant size difference between initrd sizes of F-40 and F-41?

General Hardware Discussion / KVM cross-endian guest on POWER8 / IBM S822L

« Last post by kth5 on November 19, 2024, 02:08:49 am »

Hi everyone,

I recently acquired a IBM S822L dual socket system and now am starting to get to the point of using KVM/libvirt to bring guests to it. As I was used to on my Blackbird I could run big-endian guests without much performance penalty at all running little-endian on the host.

However, on the POWER8 it seems that no matter what I do, I get up to 50% steal time inside a VM when the bare-metal and the VM are otherwise completely idle. When I put any load on the VM it gets worse and jumps up to 80% or more making any vCPU config moot. This only happens when running a big-endian guest kernel and userland, which I need for my build-bots.

A bit of background of what I'm dealing with here:
* dual POWER8E 10 core SMT8 / 256GB RAM running Opal on latest available firmware
* no entitlements beyond basic & micro LPAR and the usual AIX
* bare-metal runs ArchPOWER ppc64le with SMT switched off as required
* guests I'm testing with run ArchPOWER ppc64 or ppc64+32bit userland
* kernel version is 6.11.9 on bare-metal & guests
* Qemu 9.0.3/9.1.1 w/ libvirt 10.8.0

I've tried the following all exhibiting the same steal time issue:
* single vCPU w/o threads
* single vCPU w/o threads pinned to a physical core & NUMA zone
* dual vCPU w/ 8 threads (SMT)
* dual vCPU w/ 8 threads pinned to a physical core & NUMA zone (SMT)

What I did not try is running actual PowerKVM. It seems too outdated for my liking and I'd rather have a recent package base as close to upstream as possible.

Running ppc64le in the guest does not show the problem at all and performs splendidly.

Bit at a loss here and I would rather I not yet call it a lost cause.

What exactly appears on screen? If you boot it from the BMC web interface, what appears on the virtual serial port output?

Exactly, this time Fedora has outdone itself with a bug so big that it compromises the entire distro. I strongly advise you not to update because you will lose everything if you do not have another distro installed on another hard disk to be able to download all the files you may need... Be very careful!

I can confirm MauryG5's issue.  When trying to update from 40 to 41 via console it would not install due to a "watchman" issue.  After being pestered via notifications to update I decided to give "Software" a shot at the update.  It installed 41 but now NO version of Fedora will load.  "Error loading initrd" is the error given.  Even after rolling back via Timeshift I get the same error.  On a side note that may be related, my openSUSE will start but is very slow and will not fill windows.  For example if I open any file browser I get the window outline but it is filled with the desktop image and no radio gadgets.
