- | ==== Computer memory ==== | + | ==== The basics before starting ==== |
- | FIXME | + | Once you have verified that your Windows is recent enough, you should also: |
+ | * Your should really **install the [[other:win10apps#windows_terminal|Windows terminal]]**, because it will be one of useful the ways to open ''Ubuntu'' terminals, once ''Ubuntu'' is installed | ||
+ | * **Know how to use copy-paste** in: | ||
+ | * a //Windows Terminal//: [[https://docs.microsoft.com/en-us/windows/terminal/selection|Selecting text in Windows Terminal]] | ||
+ | * an old ''cmd'' command prompt or a //PowerShell//: FIXME | ||
+ | * It will be useful to **be able to [[other:win10config#displaying_hidden_folders_and_files_and_the_files_extension|see hidden folders and files]]** | ||
+ | * **Have some basic knowledge of Linux**... | ||
+ | * Get some [[other:newppl:starting#useful_documentation_for_beginners|basic Linux documentation]] if required | ||
+ | ==== Computer CPU and memory ==== | ||
- | ==== Disk space ==== | + | Contrary to other virtual machines, WSL is well integrated with the Windows operating system and the hardware drivers and has a **low default CPU and memory footprint**! |
- | FIXME | + | * You should be able to //play// with WSL even with 8 Gb of RAM, but 16 Gb is recommended |
+ | * Of course, depending on what you need to do on your computer, a better processor will always help | ||
+ | * WSL+Ubuntu will use more CPU and RAM if you use it for running CPU and/or memory intensive processes! As would be the case with any Windows application... :-) | ||
- | * //Enough// space on ''C:\''. Microsoft instructions say //The Windows Subsystem for Linux only runs on your system drive (usually this is your C: drive)// | + | |
- | * Exporting a //simple// Ubuntu configuration (after doing everything from //Base installation// to //Advanced configuration// below) with the [[other:win10wsl#creating_a_backup_of_the_linux_running_in_wsl|wsl --export]] command generated a 2.7 Gb tar file (uncompressed), so it's probably good to **start with at least 3 Gb of free space on ''C:\''** (and you always need to keep enough free space on ''C:\'' for regular Windows operation) | + | ==== Disk usage ==== |
- | * The Linux ''/'' and ''/home'' partitions will always be on ''C:'', but the data files can be on any Windows disk/partition (or external drive) of the computer | + | |
- | * the Windows partitions will be available and accessible in ''/mnt/'', so you can store data on other partitions (e.g. the content of the Windows ''D:\'' partition will be available in ''/mnt/d'' in Linux) | + | === Overview === |
- | * The files will be installed in **hidden partitions of the current user's directory on ''C:\''**: e.g. ''C:\Users\<your_login>''. Other users of the same Windows 10 computer would have to install Ubuntu again, in their own user directory | + | |
- | * Checking the properties of ''C:\Users\<your_login>'' will **not** report an accurate size and number of files, because lots of files and directories are hidden! On the test laptop, the reported size of the user backed up directory (with [[other:win10apps#syncbackfree|SyncBackFree]]) was ~20 Gb (user data, WSL+Ubuntu, custom install of the CDAT 8.1 python distribution) | + | * ''WSL'' is part of the Windows operating system and will be installed (and updated) on ''C:\'' |
- | * Be sure to monitor the remaining free space on ''C:''! | + | * The Linux installation(s) will be installed (and updated) on ''C:\'' |
- | * Note: it seems that [[other:win10wsl#restoring_a_wsl_backup|wsl --import]] can restore a backed-up Linux to a user specified location. Maybe this can be used for moving Ubuntu... | + | * They can only be relocated to other partitions afterwards |
- | * Check [[https://github.com/MicrosoftDocs/WSL/issues/412|how to move the vhdx of wsl2 to other disk]] and [[https://github.com/microsoft/WSL/issues/4320|[WSL 2] move VHD File]] for relocating a WSL (1 or 2) installation if you don't have enough space on ''C:'' | + | |
+ | * => We should **start with at least 10 Gb of free space on ''C:\''** (but more space is always better and safer) | ||
+ | * The initial installation will not use much space (2-3 Gb), but we always need space on ''C:\'' for other applications and Windows maintenance (temporary files, updates, ...) | ||
+ | |||
+ | <WRAP center round alert 60%> | ||
+ | FIXME The rather technical //Disk usage// sections below should be moved somewhere else! | ||
+ | </WRAP> | ||
+ | |||
+ | |||
+ | === How does it work? === | ||
+ | |||
+ | WSL+Linux seems to use a combination of actual Windows files/folders and ''ext4'' Linux partitions stored in ''.vhdx'' ([[https://docs.microsoft.com/en-us/openspecs/windows_protocols/ms-vhdx/83f6b700-6216-40f0-aa99-9fcb421206e2|Dynamic Virtual Hard Disk]]) files. The Linux disk (of type ''ext4'') is stored in a single ''some_name.vhdx'' Windows file that will automatically grow until it reaches a predefined maximum size of 256 Gb (if there is enough space on the Windows disk...) | ||
+ | |||
+ | * Check [[https://docs.microsoft.com/en-us/windows/wsl/vhd-size|Expand the size of your WSL 2 Virtual Hard Disk]] if you need more than 256 Gb | ||
+ | * Check the following threads if you want to reduce the size of the ''vhdx'' file: | ||
+ | * [[https://superuser.com/questions/1606213/how-do-i-get-back-unused-disk-space-from-ubuntu-on-wsl2|How do I get back unused disk space from ubuntu on wsl2?]] | ||
+ | * [[https://github.com/microsoft/WSL/issues/4699#issuecomment-1136319012|WSL 2 should automatically release disk space back to the host OS]] | ||
+ | * [[https://docs.microsoft.com/en-us/powershell/module/hyper-v/optimize-vhd?view=windowsserver2019-ps|Optimize-VHD]] | ||
+ | |||
+ | === Disks seen from Linux === | ||
+ | |||
+ | The disks and partitions usage, as seen from Linux, can be displayed with ''df -h'' | ||
+ | |||
+ | <code>stdu@sadira034:~$ df -h | ||
+ | Filesystem Size Used Avail Use% Mounted on | ||
+ | /dev/sdb 251G 1.5G 237G 1% / | ||
+ | tmpfs 6.2G 0 6.2G 0% /mnt/wsl | ||
+ | tools 472G 118G 355G 25% /init | ||

+ | D:\ 480G 2.6G 478G 1% /mnt/d</code> | ||
+ | |||
+ | * The ''251G'' //Size// of ''/'' depends on the [[https://docs.microsoft.com/en-us/windows/wsl/vhd-size|256G default size]] of the growing virtual disk where Linux is installed | ||
+ | * The ''/mnt/c'' and ''/mnt/d'' are the way to access the Windows ''C:'' and ''D:'' disks from Linux, and their //Size// is the actual size of the Windows disks | ||
+ | * Some //Filesystems// like ''drivers'' are actually Windows file systems! | ||
+ | * <code>stdu@sadira034:/usr/lib/wsl/drivers$ du -sh /usr/lib/wsl/drivers | ||
+ | 9.1G /usr/lib/wsl/drivers | ||
+ | |||
+ | stdu@sadira034:/usr/lib/wsl/drivers$ du -sh /mnt/c/Windows/System32/DriverStore/ | ||
+ | 9.1G /mnt/c/Windows/System32/DriverStore/</code> | ||
+ | |||
+ | |||
+ | === Some important disk locations === | ||
+ | |||
+ | * Accessing **Windows files from Linux**: ''/mnt/''\\ e.g ''C:\'' is available in ''/mnt/c'' | ||
+ | |||
+ | * Accessing **Linux files from the Windows Explorer**: ''\\wsl$'' | ||
+ | |||
+ | * WSL+Ubuntu installation: | ||
+ | * Main directory: ''C:\Users\your_login\AppData\Local\Packages\CanonicalGroupLimited.UbuntuonWindows_79rhkp1fndgsc'' | ||
+ | * //vhdx// file: ''C:\Users\jypeter\AppData\Local\Packages\CanonicalGroupLimited.UbuntuonWindows_79rhkp1fndgsc\LocalState\ext4.vhdx'' | ||
+ | * <code>stdu@sadira034:~$ ls -lh /mnt/c/Users/jypeter/AppData/Local/Packages/CanonicalGroupLimited.UbuntuonWindows_79rhkp1fndgsc/LocalState/ext4.vhdx | ||

+ | |||
+ | |||
+ | === Sample disk usage === | ||
+ | |||
+ | * Disk size after the initial installation of //Ubuntu 20.04 LTS//\\ ''-rwxrwxrwx 1 root root 1.2G Aug 24 15:20 /mnt/c/Users/jypeter/AppData/Local/Packages/CanonicalGroupLimited.UbuntuonWindows_79rhkp1fndgsc/LocalState/ext4.vhdx'' | ||

+ | * Size of the [[other:win10wsl#creating_a_backup_of_the_linux_running_in_wsl|backup tar file]] of this installation, generated with ''%%wsl --export%%'': ~1.4 Gb | ||

+ | ==== Hyper-V requirements ==== | ||
+ | |||
+ | <WRAP center round tip 60%> | ||
+ | You can skip reading this WSL //requirement// if you are installing WSL for the first time, and are therefor directly installing WSL 2 | ||
+ | |||
+ | Come back later if you have problems | ||
+ | </WRAP> | ||
+ | |||
+ | |||
+ | WSL 2 needs the //Virtual Machine Platform// to be enabled on your computer. If you have never used WSL before, you can probably go directly to the [[other:win10wsl#base_installation|Base installation]] section and ''wsl'' should install everything correctly | ||
+ | |||
+ | If you have problems (e.g. [[https://docs.microsoft.com/en-us/windows/wsl/troubleshooting#error-0x80370102-the-virtual-machine-could-not-be-started-because-a-required-feature-is-not-installed|The virtual machine could not be started because a required feature is not installed]]), or if you are updating WSL 1 to WSL 2, type ''systeminfo'' in a PowerShell to check if your machine meets the [[https://docs.microsoft.com/en-us/virtualization/hyper-v-on-windows/reference/hyper-v-requirements?source=recommendations#verify-hardware-compatibility|Hyper-V requirements]] | ||
+ | |||
+ | If you get a ''No'' for one of the ''Hyper-V requirements'', check the //virtualization// settings in your [[other:bios#entering_the_bios|computer BIOS]].\\ You can have a look at the [[https://en.wikipedia.org/wiki/X86_virtualization|x86 virtualization]] wikipedia page if you are wondering what ''VT-x'' and ''VT-d'' means for //Intel// processors (''AMD-v'' and ''AMD IOMMU'' for //AMD//) | ||

+ | ==== Upgrading WSL 1 to WSL 2 ==== | ||
+ | |||
+ | <WRAP center round tip 60%> | ||
+ | You will be able to run existing WSL 1 installations with WSL 2, so upgrading should not be a problem! | ||
+ | </WRAP> | ||
+ | |||
+ | |||
+ | === Determining which version of WSL is installed === | ||
+ | |||
+ | If you have never used WSL on a computer, WSL 2 will be installed directly when you follow the [[other:win10wsl#base_installation|Base installation]] steps | ||
+ | |||
+ | You can determine if your installed Linux distributions are running on WSL 1 or WSL 2 by typing ''wsl -l -v'' in a PowerShell, but if you are not sure if you are currently using WSL 1 or WSL 2 for running Linux, you can check if [[https://github.com/MicrosoftDocs/WSL/issues/1599|Is there an easy (PowerShell?) way to get more information about WSL?]] has been answered, or make the following checks | ||
+ | |||
+ | * ''wsl --update'' will give the same output (i.e. the installed Linux kernel version) for both WSL 1 and WSL 2 | ||
+ | * <code>PS C:\Users\jypeter> wsl --update | ||
+ | Recherche de mises à jour en cours... Veuillez patienter | ||
+ | Aucune mise à jour n’est disponible. | ||
+ | Version du noyau : 5.10.102.1</code> | ||
+ | |||
+ | * ''wsl --status'' will display again the kernel version if you already have WSL 2, but **will display a link to the WSL installation page if you are running WSL 1**: https://aka.ms/wsl2-install | ||
+ | * <code>PS C:\Users\jypeter> wsl --status | ||
+ | Distribution par défaut : Ubuntu | ||
+ | Version par défaut : 2 | ||
+ | Activez la fonctionnalité Windows de plateforme de machine virtuelle et assurez-vous que la virtualisation est activée dans le BIOS. | ||
+ | Pour plus d’informations, rendez-vous sur https://aka.ms/wsl2-install</code> | ||
+ | |||
+ | |||
+ | === Prerequisites === | ||
+ | |||
+ | * If WSL 1 is already running, you should have no problem with the [[other:win10wsl#prerequisites|disk and memory requirements]] | ||
+ | * For WSL 2, you also need to meet the [[other:win10wsl#hyper-v_requirements|Hyper-V requirements]] | ||
+ | |||
+ | === Upgrading WSL === | ||
+ | |||
+ | |||
+ | [[https://docs.microsoft.com/en-us/windows/wsl/install-manual#step-3---enable-virtual-machine-feature|Activate the Virtual Machine Platform]] (just the //Step 3// instructions) and **reboot the computer** | ||
+ | |||
+ | After rebooting, go back to the [[other:win10wsl#determining_which_version_of_wsl_is_installed|Determining which version of WSL is installed]] section above, and check that you are now using WSL 2 | ||
