My VirtualBox setup for Windows interop

README.md

Setup

• Fedora XFCE (seamless mode only works on X11 currently)
• Setup shared folder (for Guest->Host communication):
  • C:\ -> /mnt/c
  • %USERPROFILE%\Documents -> ~/winhome
• Use NAT and a Host-Only Adapter (Or bridged on vmware. Trust me, it'll save a lot of time)
• Setup sshfs-win for Host->Guest access (or see below for smb configuration)

Files

1. sshfs.ps1 -> Listens on ~/winhome/vmstatus and mounts mapped drive automatically.
2. suspendwatcher.sh -> Test if the VM is suspended / restarted / shut down and writes to ~/winhome/vmstatus

README_SAMBA.md

After 10 years I finally got samba to work.

smb.conf:

[global]
	workgroup = WORKGROUP
	security = user

	passdb backend = tdbsam
	lanman auth = no
	ntlm auth = yes
	client lanman auth = no

[homes]
	browseable = no
	writable = yes

Use this to allow samba to r/w to home directories:

setsebool -P samba_export_all_rw=1

Allow samba to use [homes]:

setsebool -P samba_enable_home_dirs=1

Do not use semanage fcontext to change the fcontext of home dir. It'll break everything.

        }
    }
