Skip the BIOS hassle! Want to know if your Linux system can handle virtual machines with blazing speed using KVM? Run the kvm-ok command. It's the quickest way to check if your hardware has the virtualization support you need on Intel or AMD CPUs. No more digging through BIOS menus – get your answer instantly at the CLI! 🚀 See this page for more info:

"probably won't ever be finished"-things dumping

1 and 2 - this was the idea of two-art post for ash's (from final space) crush on nightfall and how she acts on it in her two life periods

3, 4 and 5 - it's my favourite 30-something p.e. teacher and his 16 basketball/musician student ship (and THE FIRST EVER ship in general, it was my ship long before i knew what the ship even is) from russian tv show called ranetki (keep in mind the ship become legit canon in the actual show!!!! man some of yall wasn't a russian teen in 10s and it shows. shit was crazy and thank god i was lucky to be an eye witness of it)

6 and 7 - lunter. from the owl house for the ones who doesn't know them yet. their the best, lunter shippers are the best. if you ship lunter you have a great taste, my congrats, kisses in the neck (if you're into it only of course)

8 - it's supposed to be clauderry (from the dragon prince). i don't know how they even made me like them but here we are. i love them. they're my cutties

9 - chenford (from the rookie). they're canon btw. thank fucking god they are

10 - it's just an art my friend asked me to do. in 2022. april. 10th. and since you see it in "probably won't ever be finished"-things dumping.... oufff

Sidetrack: ChromeOS Flex... on a Virtual Machine... with Single GPU Passthrough...

the prospect of running ChromeOS on anything more powerful than a microwave oven is unfathomably cursed - wheezus2000 on discord

So... where do we start here... *checks notes* ah! So yeah, last Sunday I showcased a virtual machine running ChromeOS Flex (the most barebones GUI your grandma can only recognize) over to the aptly named r/ChromeOSFlex subreddit. It was a lot of work but it does work somehow.

Anyways, here's a tutorial to get this abomination up and running using virt-manager!

Prerequisites:

You will need:

ChromeOS Flex Recovery Image

A decent hard drive space (around 24GB is enough)

A nice dedicated GPU (because I'm not sure if it'll work with an iGPU)

more than 4GB of RAM (8GB or more is recommended)

IOMMU support

Lots of patience (you'll see why in a moment)

On the software side, you'll need:

KVM and QEMU

libvirtd and virt-manager

GRUB or any bootloader already set-up for GPU passthrough

On the skills necessary:

Having familiarized with the concept of Linux, and basic command line stuff

Having followed instructions precisely

Potentially, having skills in compiling software and/or fiddling with the operating system and the Linux kernel as well

and... not having an attention span of a script kiddie

Process

Visit this link to download the recovery image from Google.

Scroll down to this part of the page. Click on "ChromeOS Flex installer image".

This would then be downloaded.

After that, unzip the file to a convenient place. This would take ~6GB of storage space.

Install the software prerequisites using your favorite package manager.

Once having virt-manager installed, click on the new button.

From there, select "Import existing disk image".

Click on Browse. Then select "Browse Local" to find the recovery image.

In my case, that'll be in the folder called vmdk, stored in my os folder on one of my hard drives. Select the "chromeos_*_reven_recovery..." file.

In the "Choose the operating system you are installing" prompt, select linux2022.

In the memory tab, pick 4096MiB and select how many cores you want to be assigned.

You must select "Customize configuration before install" as we tweak some things.

In the prompt that follows, here's what you need to change:

Firmware: BIOS -> UEFI

Disk: VirtIO -> USB

Video: Anything else -> VirtIO

Now add a virtual hard drive by clicking the "Add Hardware" button. It should be 20GB or larger, SATA bus. VirtIO bus doesn't work as it wouldn't be recognized.

Remove any Consoles, RNG and start the install.

Here's the configuration if you follow these steps:

After starting, you can now follow the steps in installing ChromeOS Flex. It should be straightforward, however the graphics are still glitchy as it seems. It'll be fixed once we added our dGPU.

However, ChromeOS at boot will, and definitely (in my case) crash and bootloop a couple times, even when installed, before landing you to the desktop.

If for some reason, the USB tablet device doesn't work or if you prefer a cursor, switch the USB tablet for a PS/2 or USB mouse.

Once installed, you can see your desktop glitching. If you, somehow can navigate the system, you can now turn it off and set up Single GPU Passthrough. I used this one by risingprismtv. Follow the instructions provided in the wiki, and apply it to your VM. This can (and will) be complicated (especially when dealing with IOMMU groups), as it may break your setup, so please proceed with caution. Any issues with the script can be reported through their Discord server.

After setting the scripts, this is my current VM setup:

Now it's time to boot the VM, and voila! You can now use ChromeOS Flex while staying under Linux!

Predicaments, and possible issues

No, it does not work under Windows, well, without complications apparently.

Possible VM bootloops, just like I said. Seems related to the graphics, I presume. Though, this only happens multiple times, before working normally.

You can't update the VM, apparently.

Screenshots

And as always, see ya later!

Chimera-Linux with btrfs

Chimera Linux is a rather new from the ground up Linux Distribution built with LLVM, MUSL, BSDUtils and dinitit comes with GNOME and KDE Plasma. It, however doesn't come with a installer so here's how to install the KDE flavour with btrfs root and home directories plus a swap partition for use in Linux KVM with UEFI.

Step 1. Get a Chimera live image from https://repo.chimera-linux.org/live/latest/

I use the chimera-linux-x86_64-LIVE-XXXXXXXX-plasma.iso image with KDE Plasma 6 and the following steps assume you do the same.

Step 2. Boot the live image

Step 3. Prepare the target disk with KDE Partition Manager

/dev/vda /dev/vda1, vfat, EFI System, 500 MB /dev/vda2, btrfs, Root FS, subvols @ & @home , rest of the disk /dev/vda3, swap, SWAP FS, 2x RAM Size

Step 4. Open Konsole and do the following

doas -s mkdir -p /media/root mount -t btrfs /dev/vda2 /media/root chmod 755 /media/root btrfs subvolume create /media/root/@ btrfs subvolume create /media/root/@home btrfs subvolume set-default /media/root/@ umount /media/root mount -t btrfs -o compress=zstd:5,ssd,noatime,subvol=/@ /dev/vda2 /media/root mkdir -p /media/root/home mount -t btrfs -o compress=zstd:5,ssd,noatime,subvol=/@home /dev/vda2 /media/root/home mkdir -p /media/root/boot/efi mount -t vfat /dev/sda1 /media/root/boot/efi

let's bootstrap our new chimera system

chimera-bootstrap -l /media/root exit

time to chroot into our vergin system

doas chimera-chroot /media/root

time to bring everything up to date

apk update apk upgrade --available

if something is iffy

apk fix

we want our swap to show up in the fstab

swapon /dev/vda3

Let's build a fstab

genfstab / >> /etc/fstab

install the latest LTS Kernel

apk add linux-lts

install the latest released kernel

apk add linux-stable update-initramfs -c -k all

time for EFI GRUB

apk add grub-x86_64-efi grub-install -v --efi-directory=/boot/efi update-grub

install KDE, Firefox, Thunderbird

apk add plasma-desktop flatpak smartmontools ufw firefox thunderbird qemu-guest-agent-dinit spice-vdagent-dinit

Set root password

passwd root

create main user

useradd myuser passwd myuser

add user to relevant groups

usermod -a -G wheel,kvm,plugdev myuser

Set hostname

echo chimera > /etc/hostname

set timezone

ln -sf /usr/share/zoneinfo/Europe/Berlin /etc/localtime

Configure some services

syslog-ng

dinitctl enable -o syslog-ng

sshd

dinitctl enable -o sshd

KDE Login Manager

dinitctl enable -o sddm

only needed when in KVM VM

dinitctl enable -o spice-vdagentd dinitctl enable -o qemu-ag

network time client

dinitctl enable -o chrony

network manager defaults to dhcp client on first ethernet interface

dinitctl enable -o networkmanager

optional: enable firewall if installed

dinitctl enable -o ufw

see the firewall status

ufw status

configure flatpak

flatpak remote-add --if-not-exists flathub https://dl.flathub.org/repo/flathub.flatpakrepo

just to be sure

update-initramfs -c -k all update-grub

exit from chroot

exit

umount drive

doas umount /media/root/boot/efi doas umount /media/root/home doas umount /media/root

Step 5. Reboot the System
