Error when starting a VM with VirtioFS device configured: "Unable to find a satisfying virtiofsd"

[matheuswillder]

As the title says and as commented in flathub/org.virt_manager.virt-manager#33, when trying to start a VM with a VirtioFS device configured, this error is displayed:

Previously I also faced this error when I used Virt-Manager installed through apt, and I solved it by installing the virtiofsd package in the host (Debian), but that obviously doesn't work here since both Virt-Manager and QEMU are installed using Flatpak (User Session).

Is there any way to get it working using Flatpak, or in this case do I need to resort to 9P for file sharing?

Oh interesting, maybe this should be included on the flatpak then

[tulilirockz]

You dont need to resort to anything, Ill just update the manifest with the virtiofsd binary in there

Ok thanks!

9P worked out of the box, I just needed to change the driver from virtiofs to virtio-9p through Virt-Manager, so I thought this could be some limitation imposed by the Flatpak sandbox for virtiofs.

So, after some work, apparently this requires a patch to libvirt, and itll take a bit until that gets merged on the main virt-manager flatpak. 9P should be a proper workaround for now

Thanks!

Edit: Also, thank you very much also for maintaining this QEMU extension for Virt-Manager Flatpak. I've been using it for only 2 or 3 days and it's amazing how well it works even though it was released just recently :)

@tulilirockz

Really appreciate your work here, but any progress on this? I think there are some issues with #11?

Currently, when using Windows guest, it is impossible to share files as 9P is not supported in Windows and WebDav also doesn't work with virt-manager.

[tulilirockz]

There really hasn't been any work on this, everything that has been figured out is on that PR :( I personally haven't even gotten it working via a hack or anything yet, someone needs to investigate this as well...

[matheuswillder]

I experienced data loss twice while transferring files using 9p between a Linux guest and a Linux host. So if anyone is going to use 9p, verify the integrity after copying the files.

I've been using this QEMU extension since I opened this issue (almost a year ago, how time flies lol), and I really appreciate the dedication to maintaining it. Thanks @tulilirockz!
