Sorry I do not have relavant experience with the windows VM tools.
Given VMware has dispointed you could try VirtualBox.
Fedora supports WSL2 with F42. Could you run your app under Fedora on WSL2?
I did some testing of Fedora for WSL2 and it worked very well in my limited testing.
You can tweak a rpi to create this feature. Once more Jeff Geerling shows how to (NUT on a raspberry pi):
Yes that would be a great idea, I have tried it once but couldnât find official image but now I think there is a good news from Fedora, I will check it out, thank you so much.
There should be wsl fedora image and instructions as part of the f42 beta.
There is topic Fedora Linux 42 Beta is here (the announcement comments topic!) where asked about wsl
Btrfs writes atomically, meaning itâs all or nothing.
Btrfs uses a technique called Copy-on-Write (CoW) for all writes to the filesystem. CoW means that a write always happens in a new block on the disk instead of overwriting an existing data block. Once the block is updated on disk, the metadata is updated to point to the new block. This ensures data integrity in case of a failed write - you either have the original data or the new data. If a write fails in a traditional filesystem, the contents of a datablock may instead be incomplete or wrong.
Obviously, everything relies on the hardware behaving correctly:
In an ideal world, the device does what it promises. The filesystem assumes that this may not be true so additional mechanisms are applied to either detect misbehaving hardware or get valid data by other means. The devices may (and do) apply their own detection and repair mechanisms but we wonât assume any.
The following assumptions about storage devices are considered (sorted by importance, numbers are for further reference):
- atomicity of reads and writes of blocks/sectors (the smallest unit of data the device presents to the upper layers)
- thereâs a flush command that instructs the device to forcibly order writes before and after the command; alternatively thereâs a barrier command that facilitates the ordering but may not flush the data
- data sent to write to a given device offset will be written without further changes to the data and to the offset
- writes can be reordered by the device, unless explicitly serialized by the flush command
- reads and writes can be freely reordered and interleaved
The consistency model of BTRFS builds on these assumptions. The logical data updates are grouped, into a generation, written on the device, serialized by the flush command and then the super block is written ending the generation. All logical links among metadata comprising a consistent view of the data may not cross the generation boundary.
Yeah, I just downloaded the latest F42 image and tried installing Apache, Caddy, and Firewalld. Caddy and HTTP work fine when starting the system daemon, but the firewall daemon doesnât start, showing an error. I am testing on Windows Server 2022.
But I donât think mirrored network adapter option is available on windows server, thus I can not access any hosted applications on Fedora I guess
There microsoft docs of network setup I found Accessing network applications with WSL | Microsoft Learn
You will need to change the networking mode.
What error do you see for the firewall?
I had already changed my WSL2 to use mirrored nedworking:
$ cat /mnt/c/Users/barry/.wslconfig
[wsl2]
networkingMode=mirrored
Iâve now used the powershell commands to open up the HyperV firewall to allow SSH and HTTP in.
New-NetFirewallHyperVRule -Name "MyWebServer" -DisplayName "My Web Server" -Direction Inbound -VMCreatorId '{40E0AC32-46A5-438A-A0B2-2B479E8F2E90}' -Protocol TCP -LocalPorts 80
New-NetFirewallHyperVRule -Name "Fedora-SSH" -DisplayName "Fedora SSH" -Direction Inbound -VMCreatorId '{40E0AC32-46A5-438A-A0B2-2B479E8F2E90}' -Protocol TCP -LocalPorts 22
With these changes I can ssh into the Fedora WSL instance and access the web server.
Yeah I have changed the network mode to mirrored but I get this error:
wsl: Mirrored networking mode is not supported: Windows version 20348.2461 does not have the required features. Falling back to NAT networking.
I tried using netsh command following the documentation Accessing network applications with WSL | Microsoft Learn
But no luck, I can access default Apache page with the Fedora IP but couldnât with the Windows Server IP.
The firewalld shows the following error

I am testing on windows 11 23h2.
Thankfully, the port forward thing worked after restarting the server. But now I am struggling with starting the WSL when the server starts and able to access the web applications.
A web search for â startup wsl on bootâ comes up will a number of promising leads.
This is not true for any filesystem. There are critical I/O operations, the window in which those exist are smaller with journaled filesystems, and even smaller for CoW filesystems.
