@JoelLinn You will probably find the image you need by going to the website of the desired distro. And looking for ppc64. We use image for cloud, but there is also iso.

running the debian ppc64 installer
Joel Linn
@JoelLinn
Yes i tried that. Uploaded the netinst iso and it booted the installer. It couldnt mount the disk though. I also tried mounting /dev/sr0 and /dev/disks/[...] on the installer shell but to no avail.
Alexandre Bencz
@bencz
oh yeah... this is a problem...

@JoelLinn
It seems to be a kernel bug, I tried an earlier version (kernel 5.5) https://cdimage.debian.org/cdimage/ports/snapshots/2020-04-19/debian-10.0-ppc64-NETINST-1.iso
which mounts the device fine
Joel Linn
@JoelLinn
@rpsene I tried to get around building an image from scratch...
When creating an instance from an ISO image, doesn't it add an hard drive? Because there is just the ISO and no hard drive. How would one install from an ISO then like @jr-santos98 and @bencz suggested?
Alexandre Bencz
@bencz
"The first step is to create a common Debian image, which can be done using several different approaches."
what kind of approach can be used?
Alexandre Bencz
@bencz
oh yeah, I will try that Debian 8 B.E image!

we just don't know the user and password
Junior Santos
@jr-santos98
@bencz @JoelLinn How you used a qcow2 image. Probably, when you created the VM, OpenStack injected your ssh key there. Try to access the VM over an ssh connection. If you’ve never done this in the minicloud, we have this tutorial: https://github.com/Unicamp-OpenPower/minicloud/wiki
Alexandre Bencz
@bencz
I downloaded the Debian image from the link I sent here .... I tried to connect via ssh but was unsuccessful ...
Joel Linn
@JoelLinn
@bencz
Built my own image https://wolke.linn.io/s/rNF4jYjS3JQDBLt
it has autologin on vnc, so you may want to disable that:
sudo rm /etc/systemd/system/getty@tty1.service.d/autologin.conf
sudo rm /etc/systemd/system/serial-getty@.service.d/autologin.conf
If you want to create your own image see my fork:

Rafael Sene
@rpsene
@jr-santos98 could you follow the process to create an image that can be added as public at Minicloud?
Joel Linn
@JoelLinn
autologin can be disabled by modifying build scripts but i didnt bother
Alexandre Bencz
@bencz
@JoelLinn oh yeah!!
Thanks!
Junior Santos
@jr-santos98
@JoelLinn I got the following error when trying to create the image: https://oplab9.parqtec.unicamp.br/pub/teste/junior/teste-debian.png
But, I will try to put the image you made as a publisher. As soon as I get it, I'll let you know.
Alexandre Bencz
@bencz
I'm using that Debian image from @JoelLinn ..., just making a stress test...

Joel Linn
@JoelLinn
@jr-santos98 if debootstrap cant run /bin/true thats usually because qemu-user-static and/or binfmt-support are not installed
it needs those to chroot into the image and run scripts/apt in it using the target arch.
did you install all packages i have listed on top of the readme? what is the system image you are trying to build this on? debian 10?
Joel Linn
@JoelLinn
@bencz I see you have filed an issue with godbolt. Did you just try the official site or did someone try to host it themselves?
Junior Santos
@jr-santos98
@JoelLinn I added your image as public on Minicloud. It is named as: "Debian 11 ppc64 - BE".
Rafael Sene
@rpsene
nice!
Thanks @jr-santos98 and @JoelLinn !!!
Joel Linn
@JoelLinn
Cool, did you use my upload or did you build it yourself?
@neosaldina thanks for the question...
Joel Linn
@JoelLinn
Tbh i dont feel to bad about „bad“ performance on BE with Power8 🤷🏽‍♂️ I regard that combination as a research tool, afaik user code can still be compiled with newer instructions enabled
mind everything before Power8 is unsupported on all modern ppc64le distros. So ppc64 is the only viable option for those systems
Rafael Sene
@rpsene
@JoelLinn we will be adding P9 back to the cloud soon.
Joel Linn
@JoelLinn
cool, was there some issues with the server hardware or why was it taken down ?
Rafael Sene
@rpsene
@JoelLinn we had a bad time with slow VMs with the available version of kvm back in the begining of this year when we upgra
upgraded the openstack
Rafael Sene
@rpsene
we are going to upgrade again with the latest version which includes an upgraded kvm with fixes

Hi, I created an instance with FreeBSD13-head-r359571 image but I can't figure how I connect via SSH, I tried to connect to freebsd@minicloud.parqtec.unicamp.br with no chance, does anyone has a clue here?
Joel Linn
@JoelLinn
Did you use the correct port?
also try root, itll tell you the correct username (at least for most linux images)
mamonet
@mamonet_gitlab
Yes, I used the correct port. I also create a new user but I'm not sure if freebsd@minicloud.parqtec.unicamp.br is the correct host I should connect to!
