It works as if you added a SCSI controller to Amiga.
It works on disk images. It has nothing to do with sharing resources between guest and host in QEMU.
You will not share resources.

@derfs
I checked it on AmigaOne and it works. Thank you :- )
Out of curiosity, I also checked it on sam460 - it does not work here.
You wrote about peg2 and A1 in the requirements, so it does not have to work.

Thanks again.

@smarkusg

looks like it doesnt play nice with diskcache.library.kmod, so as a temp workaround it should work for now on sam460 if that is commented out.

this is using -device virtio-scsi-pci.... device and not the 'non-transitional' device.

*edit*

That was quick! Its out of the upload queue - https://os4depot.net/?function=showfil ... er/handler/virtio9pfs.zip

@kas1e

I believe this (https://os4depot.net/download.php?file=queue/virtio9pfs.zip) is what you were after? Currently in the upload queue on os4depot.


Virtio9PFS-handler

==================



A FileSysBox-based handler for AmigaOS 4.1 FE that mounts QEMU host-shared

folders as DOS volumes via the VirtIO 9P (9P2000.L) protocol.



Status: Beta -- tested on QEMU AmigaOne (legacy VirtIO) only. Pegasos2

(modern VirtIO) is implemented but not yet validated. Use at your own risk.



Important: QEMU for Windows (x64) does not currently support -virtfs.

You need a Linux, WSL2, or macOS QEMU build to use VirtIO 9P shared folders.





What It Does

------------



When running AmigaOS under QEMU with a -virtfs shared folder, this handler

presents the host directory as a native AmigaOS volume (e.g. SHARED:). You

can browse, copy, create, rename, and delete files on the host filesystem

directly from Workbench or the Shell.

Wowow! Not that fast ! AI surely help, but you soon will wrote per driver in a day :) Cool ! Will check this out.

Can't remember, but virtfs can't work on win at all as this part of qemu code is linux only, right ?

If you use Windows, the solution is WSL2

Thanks!
It works fine on macOS on A1.
Video test to see how it works

On Linux, I have peg2 and it doesn't work properly there.
Similarly, on peg2, I have problems with Virtio SCSI....

Thats correct on Windows, but if you use the WSL2 subsystem on Windows then you can get it to work as its essentially linux.

P.S. virtfs is also available on macOS.

On QEMU Peg2 under Linux, the Virtio9PFS-handler works for me in this way.


-fsdev local,security_model=mapped,id=fsdev0,path=/home/markus/Muzyka -device virtio-9p-pci-non-transitional,id=fs0,fsdev=fsdev0,mount_tag=SHARED

Here is Virtio9PFS-handler and virtioscsi.device on Linux QEMU PEG2
*) The vtlspci command comes from a package by Falke, who is working on QEmu VirtualVGA Device.
