Hi, I've been running Qubes for a few years now and I'd like to give Spectrum a try, as I've been having some hardware and performance problems with Qubes. Is there some up-to-date guide I can follow? I found https://alyssa.is/using-virtio-wl/#demo and was able to see the weston terminal. I also tried updating to the latest commit and was able to get a nested wayfire window with: nix-build . -A spectrumPackages && ./result-3/bin/spectrum-vm (I'm fairly new to Nix, so not sure if this is the right way to do things) I managed to change the keyboard layout, mount a tmpfs for home, and increase the memory enough to start firefox, but I haven't managed to get much further. Things I tried so far: - I tried replacing wayfire with weston-terminal, to avoid the nested session. But sommelier segfaults when I do that. - I tried adding `--shared-dir /tmp/ff:ff:type=9p` to share a host directory. Then `mount -t 9p -o trans=virtio,version=9p2000.L ff /tmp` in the VM seemed to work, but `ls /tmp` crashed the VM. - I tried using `-d /dev/mapper/disk` to share an LVM partition, but `mount -t ext4 /dev/vdb /tmp` refused to mount it. - I tried enabling networking with `--host_ip 10.0.0.1`, etc, but it said it couldn't create a tap device. I guess it needs more privileges. Ideally, I'd like to run a VM with each of my old Qubes filesystems, to get back to where I was with my Qubes setup, before investigating new spectrum stuff (e.g. one app per VM). Do you have any advice on this? I see these lists are a bit quiet - I hope someone is still working on this because it sounds great :-) Thanks! -- talex5 (GitHub/Twitter) http://roscidus.com/blog/ GPG: 5DD5 8D70 899C 454A 966D 6A51 7513 3C8F 94F6 E0CC

Workflow preferences - case aarch64 support
by Ville Ilvonen 20 Jun '22

Hi all, Good news is that the work on aarch64 support has progressed to the point where the Spectrum host can be built natively and run on aarch64 HW. It's still a bunch of patches in various stages of WIP or review to spectrum or further up the stream. In short, to "nixpkgs-spectrum": 0001-Allow-static-building-of-dtc.patch 0002-Workaround-ld-script-segmentation-fault.patch /* may be not needed */ 0003-Add-imx8-specific-kernel.patch and to "spectrum": 0001-Add-imx8-kernel.patch Should anyone want to reproduce, please let me know and I'll try to find a solution to share them. Probably worth waiting for cross-compilation support unless you have powerful aarch64 at your disposal. In the meanwhile, we try to establish a mechanism to collaborate in branches of required upstream repos. It's fairly impractical to fork "nixpkgs-spectrum"-repo due to its' size, over 2GB, Which takes me to the discussion point - what's the workflow proposal on multiple people working on the same functionality in the same branch? If I'm not mistaken the email workflow creates a new branch for each author? Then someone would have to cherry-pick them to the same branch to integrate them in dev time hydra builds. Best, -Ville
