Blackbird / How to implement Secure Boot on the Blackbird
« on: July 17, 2020, 09:39:20 am »

Anyone has done it before? is there a step-by-step guide on how to implement it?

Are there risks? like getting stuck and having to reinstall everything from scratch?

Any input is appreciated.


Hi All,

I'm using this Black Bird for two weeks now. I've installed Fedora 32 with KDE/Plasma on this Power9 v2 machine with 32GB, 4 cores and plenty of disk.

When compacting the local mailboxes (Thunderbirds asks for it a few times a day) usually Thunderbird becomes unresponsive but I can use other applications. Today it froze the whole system for about a minute, I could not change application, it made remember Windows 3.1 with it's incipient multi-tasking capability.

My system barely gets over 40% memory util and vCPUs were supposed to work independently one from the others.

Any ideas of what might have happened? I wonder may be disk access. I have two disks: 128GB with boot and LVM for root/local. The second disk of 256GB I use a partition of 120GB as a LV which I added to LVM and used it full to extend /home. Both are PCI connected.

Maybe when compacting the mailboxes the access to the disk made by Thunderbird are so heavy to the point of not allowing the system anything?

Any inputs are appreciated.


Hi All,

I need to run an X86 application and have not succeeded installing any Linux distro (I've given up on Windows). I've tried Linux Mint, Ubuntu 20.04 Desktop and Fedora 32 Desktop and all failed to install. I've tried with VM Manager and also QEMU command line.

Anyone succeeded? If yes, I would appreciate very much if you can share details on how to install it.

Anyway, up to now my experience with QEMU emulating X86 has been that it is VERY slow and, no matter what I configure, it uses only one vCPU.

Thanks in advance.


I've got my new Blackbird and installed Fedora 32 on it, KVM and GNOME BOXES. When I try to create VMs I get the following error messages: "Virtualization extensions are unavailable on your system. Check your BIOS settings to enable them".

I've tried all options on PetitBoot menu but could not find how to enable virtualization extensions.

Anyone had this issue? Any help is welcome.


Operating Systems and Porting / Running a Windows VM on Fedora 32

Hi All,

I'm new to Talos. I've got a blackbird and installed Fedora 32.

I want to create a Windows 10 VM to run a few applications that are not available on Linux.

Has anyone done this before? Searching on the web I saw people writing about emulating x86 on ppc but not enough details and not specific for Talos.


Blackbird / Max resolution of the HDMI (motherborad)
« on: May 11, 2020, 02:33:35 am »
Hi All,

I've just got my new Blackbird, powered it on on loaded the pre-installed Debian.

The max resolution I get is 1024x768.

Anyone has had this issue?

According to the product page the on board HDMI is full HD, ie, capable of delivering 1920x1080.

I'd like to set it to 1920x1080. Anyone knows how to increase the resolution?

Thanks in advance,

Firmware / How to setup Secure Boot with PetitBoot
« on: April 24, 2020, 09:35:29 am »
Hi All,

I'm new to Power9 and would like to ask the community how to setup Secure Boot on PetitBoot?

Assuming a brand new system came with Debian pre installed, will I have to reinstall the OS or just "feed-in" into PetitBoot a public key from Debian to authenticate the OS signature on the boot partition before PetitBoot loads it?

An "architectural" question: does PetitBoot run on OpenBMC? I understood that PetitBoot (or maybe it is OpenBMC) runs on a separate hardware and not in the main cpu?

Thanks in advance.
