Virt-manager cannot find virtiofsd

I can start a VM from virt-manager, however, I cannot define shared directory. I see a popup window with error message.

Error starting domain: operation failed: Unable to find a satisfying virtiofsd

Traceback (most recent call last):

libvirt.libvirtError: operation failed: Unable to find a satisfying virtiofsd

I did follow instructions on following sites.

I updated channel NixOS 22.11 and rebuilt the system; Same error.

What should I do to fix this error?


add virtiofsd into your systemPackages and add following into virt-manager filesystem xml:

  <binary path="/run/current-system/sw/bin/virtiofsd"/>

Is there a different approach now?

$ find /run/current-system/ -iname *virtiofsd*

$ /run/current-system/sw/bin/virtiofsd
bash: /run/current-system/sw/bin/virtiofsd: No such file or directory

I used

[user@nixos:~]$ which virtiofsd
