Permission Denied error when I try to open the image file stored on the ZFS disk accessed through sshfs from another machine...

Hello to everyone. I would like to boot the FreeBSD 13.2 image file using Libvirt + virt-manager. I have stored the image on the external hard drive,"formatted" with ZFS while I'm using Devuan 5 installed on my ARM (32 bit) Chromebook,where I have access to the ZFS disk using sshfs using this command : sshfs -o Compression=no -o allow_root -o transform_symlinks -o password_stdin root@192.168.1.2:/mnt/zroot2/zroot2 /mnt/zroot2/zroot2 <<< 'pass' This is the error I get when I try to boot the image file using virt-manager : error : qemuProcessReportLogError:1990 : internal error: process exited while connecting to monitor: 2023-11-28T20:53:46.882586Z qemu-system-arm: -blockdev {"driver":"file","filename":"/mnt/zroot2/zroot2/OS/Chromebook/FreeBSD-guestOS/freebsd-kvm/FreeBSD-13.2-RELEASE-armv7.img","node-name":"libvirt-1-storage","auto-read-only":true,"discard":"unmap"}: Could not open '/mnt/zroot2/zroot2/OS/Chromebook/FreeBSD-guestOS/freebsd-kvm/FreeBSD-13.2-RELEASE-armv7.img': Permission denied According with this post : https://forum.manjaro.org/t/virt-manager-doesnt-work-permission-denied/10...
