I have set up a VirtualBox Fedora 11 (i386) guest on my Fedora 11 (x86_64) host system with shared folders enabled. I mount the shared folder successfully with the recommended "mount -t vboxsf share /shareddir -o rw,exec,uid=500,gid=100" command. I can successfully read and write files in the share from the guest but I cannot set the execute bit on any file in the share from the guest system. Nothing in GoogleSpace seems to address my issue let alone provide a solution. fwiw, selinux is disabled on both the guest and host and the shared folder is an ext4 file system.
- Mount the VBoxGuestAdditions.iso (e.g.
mkdir vbox && cd vbox && /media/cdrom0/VBoxLinuxAdditions.run --tar -xf
module/vboxvfs/utils.c, change line 96
mode |= mode_set (IXUSR);to
mode |= S_IXUSR;(note addition of
S_prefix... basically, always set executable flag)
sudo ./install.sh vfs-module
cd .. && rm -rf vbox
This sets the executable flag in the guest only (mode 700) for all shared files — the host still always gets mode 500 for newly created files. Hopefully a dev can make a proper fix. (slight improvement: set executable on new file creation, and keep file permissions in sync otherwise so non-executables in the host don't show up as executable in the guest)
At least this lets me do development within a shared directory.
