wow! Thanks to you, I can use my precious Arch Linux even on Oracle Cloud ARM! Kudos!
Wow! It works, thank you!
Is it possible to install Debian?
It works! :)
I skipped a heartbeat when I type 'sudo' and it said 'command not found' and then 'su -' and I didn't configured any password for root...
I guess it would be nice to set a non default password for the root user with passwd before exiting the chroot :) (just in case, the default password for the root user is just root in Arch ARM)
I was trying to do the same with netboot but I didn't get it and this solved everything, thanks!
It would be nice to mention to switch to root user in original host OS
it would also be nice to note down that the alpine account is root for login from the Console.
And like e-minguez said it would be nice to mention that to mention how to gain root access in alarm.
Thanks a lot, this saved me a lot of time!
I've also saved it to my own repo with some small changes - https://gitlab.com/C0rn3j/arch/-/blob/master/OracleCloudARM.md
I'm missing something as I don't see /dev/sda1 after doing fdisk partitioning steps... anyone ran into the same issue?
localhost:~# fdisk /dev/sda
Welcome to fdisk (util-linux 2.38.1).
Changes will remain in memory only, until you decide to write them.
Be careful before using the write command.
GPT PMBR size mismatch (105191 != 97677311) will be corrected by write.
The backup GPT table is not on the end of the device. This problem will be corrected by write.
The device contains 'iso9660' signature and it will be removed by a write command. See fdisk(8) man page and --wipe option for more details.
Command (m for help): g

You manually partition the disk at this step. Until that is done there's no sda1.
The disk is partiioned according to fdisk
Device Start End Sectors Size Type
/dev/sda1 1050624 97675263 96624640 46.1G Linux filesystem
/dev/sda15 2048 1050623 1048576 512M EFI System
but /dev/sda1 does not show under /dev when doing ls /dev only /dev/sda and /dev/sda15
so for whatever reason, the node device for /dev/sda1 was not present.... fixed it with:
mknod /dev/sda1 b 8 1
Thanks for the instructions.
If anyone runs into the problem of not being able to ssh into the machine after changing CPU count, try going into Oracle's Cloud Console. There, you should find yourself in the EFI Shell as grub couldn't be booted (at least in my case).
Enter map to get the mapping table. First entry should be FS0, so enter FS0: to change directory to the FS0 device. You should now be on the boot partition. You should be able to cd EFI/GRUB, and ls to confirm that there is the grubaa64.efi. Enter grubaa64.efi to boot grub/Arch.
You can now either login through that Console or ssh into your machine and run grub-install --efi-directory=/boot/efi --bootloader-id=GRUB again. It should now reboot as usual.
Not really sure what exactly causes it, some part isn't persistent through CPU count/memory amount changes.
has anyone had luck installing fedora cloud on this?
just a doubt, I have to create an instance with Oracle Linux 8, is that it?
The only change I would make is to switch ext4 to BTRFS + ZSTD
Followed this guide and with a few tiny mods got Arch up and running. I had one or a few reboots in the process.
When I issued poweroff - Arch powered off but the instance said Running in my Oracle account. I stopped the instance, and the next time I tried running it - it wouldn't boot up, no pings, no SSH. The console shows me Shell> only.
Is the intention here that Alpine is running 24/7 and when it stops - your Arch OS is gone or did I just miss a step somewhere and it's an easy recover?
Played with it for a while. I can get to the UEFI shell and launch EFI/GRUB/grubaa64.efi directly, but this is not a long-term solution. Right now I have a functioning system but whenever I need to power it up I need to create a serial connection and launch OS manually. I even created /boot/startup.nsh but that didn't help
Many thanks, worked like a charm
