Installing Arch Linux on VirtualBox

I recently upgraded to a new system, and instead of running Arch Linux natively I've decided to run it inside VirtualBox on Windows 10. Below I note down the steps I took, which closely follow the excellent wiki pages of archlinux. But along the way, I also noted a few other steps steps I took to make this system very comfortable, which you'll have to figure out for yourself if you like them or not!

Mount Arch Linux on VirtualBox

I couldn't find a section on the Arch wiki where these steps are listed, perhaps they are obvious, but since I think I know what I'm doing I'm just going off script here (what a great start!).

1. Start VirtualBox and click New
2. Name your machine, preferably with a descriptive but memorable name (e.g., exultant carpenter), select type Linux, and version Arch Linux (64 bit) (unless you downloaded the 32 bit version. A note on this, I recall in the past that for some machines you may need to go inside your UEFI/BIOS firmware, and enable Intel VT-x to be able to run the 64 bit version, highly recommended!)
3. Next set your RAM. I have 16GB and I want to make this my main development environment, so I decide to set mine to 8192MB, but Arch Linux requires much less than that.
4. Create a virtual hard disk now and select VDI and Dynamically allocated on the next screens.
5. Select a reasonable disk size (e.g., 40GB). Note that all of those settings are not that important at the moment as they can be changed in the future
6. Once this wizard completes, hit settings and make a few additional changes. Namely: System > Processor > 2 CPU, Display > Screen > Video Memory 128MB & Monitor Count 4 & Enable 3D (or whatever is the number of monitors that you have, hopefully >1 unless you sport a 4K monitor)
7. And finally go to Storage > Storage Tree > Controller: IDE > Optical Drive + icon > Choose Disk and navigate to where the ISO file you downloaded previously is stored (I personally moved the ISO under C:\Users\USERNAME\VirtualBox VMs\archlinux-2015.11.01-dual.
8. Click ok and you are now ready to Start the VM
9. Once started, select `Boot Arch Linux (x86_64)

Install arch on VirtualBox

We now want to install Arch Linux as guest to our Virtual Box, following the steps listed here.

1. I skip over setting up my keyboard and my internet, because I'm happy with the keyboard default and my internet works (as is verified by typing ping google.com or curl google.com)
2. Start system clock with timedatectl set-ntp true
3. This step is informational only: list block devices with lsblk, you will see sda with a size of XXG and type disk listed as well as sr0 where the ISO. Our goal here is to make sda bootable but at this point its just an unmounted, unformatted block, which is pretty useless. So let's setup a partition in sda using parted
4. Type parted /dev/sda, and once inside parted type mklabel msdos to setup a new MBR/msdos partition (why not mklabel gpt? this is because VirtualBox offers an BIOS system)
5. Next I follow the BIOS/MBR example. I run mkpart primary ext4 0% 100%, set 1 boot on, and quit
6. Format the partition in ext4 with mkfs.ext4 /dev/sda1 and mount it with mount /dev/sda1 /mnt
7. I skip over changing the mirrors
8. Install the base packages with pacstrap -i /mnt base base-devel (if this is your first time using pacman, rejoice because it will be the main reason you will love Arch Linux! You will be prompted with a few confirmation screens, just keeping hitting enter until you downloads start (this may take a few minutes, depending on the speed of your internet connection). A quick note on the questions in Linux that end with [Y/n], these are usually pretty safe questions, so you don't actually need to type Y and can just hit enter. More discussion about this here for example.
9. Generate an fstab file using genfstab -U /mnt > /mnt/etc/fstab and change root using arch-chroot /mnt /bin/bash
10. To help your locale-aware programs and libraries render text, regional monetary values, time and date formats correctly, set your Locale I type the following (assuming US): vi /etc/locale.gen, which will open the vi editor, /en_US.UTF-8, followed by the character x to delete the leading #, which uncomments the appropriate line, and finally :wq which saves and quits the file
11. Use tzselect to find your time zone, and type ln -s /usr/share/zoneinfo/Zone/SubZone /etc/localtime where Zone/SubZone is your selection. Since windows 10 is also installed on the machine, important to set hwclock --systohc --utc
12. Do not install microcode updates, as this is a virtual machine
13. Install grub package with pacman -S grub os-prober
14. grub-install /dev/sda
15. grub-mkconfig –o /boot/grub/grub.cfg
16. Next pick a hostname to refer to your machine on the network, I pick exultantcarpenter, and put this is a file as such echo exultantcarpenter > /etc/hostname. Also add this hostname to /etc/hosts by adding it as an option beside localhost (the line should look like 127.0.0.1 localhost.localdomain localhost exultantcarpenter, all separated by tabs.
17. Ensure that you machine will be able to connect to the internet when boot in the future, by running the following two commands. 1) ls /sys/class/net which will output two words to the screen, for instance enp0s8 lo. and 2) systemctl enable [email protected], where you replace enp0s8 with what your first command outputed.
18. Almost there! Next we set a password, unmount and reboot! Set a password with passwd, exit chroot with exit, unmount with umount -R /mnt, and reboot with shutdown. Once the machine is off the virtual machine, return to VirtualBox, select the machine, and remove the drive (Settings > Storage > Storage Tree, select the ISO and click on the minus sign to remove)
19. Hit start again and you are done!

Install Guest Additions

here.

What next?

At this point, you can take a break and come back later to continue the setup of all your favorite goodies for your brand new Arch Linux (xmonad, haskell, R, apache Spark, clojure).

Could not able to download arch linux iso file for virtualbox.

@Harboubacar just download a .iso file for your config from https://archlinux.org/download and add it in your VM as explained (step 7 in first part)
