Way to skip check for 'libvirt-qemu' group and user while installing guest

Hi, Debian Buster here, I'm trying to install a guest on a sshfs mount, Libvirt is checking for the user and group 'libvirt-qemu'. Is there a way to avoid that check or has anyone a way to use a mount used by sshfs with Libvirt? The SSH server has no group with the UID/GID of 'libvirt-qemu'. -- John Doe
