I share the filesystem using the following command to qemu: -virtfs local,id=fsdev0,path=$SHARED,security_model=passthrough,mount_tag=vmshared and on guest side (fstab): vmshared /mnt/vmshared 9p rw,comment=systemd.automount,trans=virtio,access=any 0 0 Versions: $ uname -a Linux manuelspc 3.11.1-1-ARCH #1 SMP PREEMPT Sat Sep 14 19:30:21 CEST 2013 x86_64 GNU/Linux $ qemu-system-x86_64 --version QEMU emulator version 1.5.2, Copyright (c) 2003-2008 Fabrice Bellard Can someone please help me to get back my writing permissions?
