=========================
Sharing folders and files from Host to KVM guest(both linux);
install samba server on Host. (system-config-samba)
Do the configuration required using system-config-samba. (adding directory to share, user name , password). (in Host) use same system-config-samba.
// to set rw permission on all folders uncomment this in /etc/samba/smb.conf
setsebool -P samba_export_all_rw on
sudo service smb restart
=========================
Then, do mount from KVM guest.
mount -t cifs //192.168.122.1/workspace /mnt/samba -v
Note, here workspace should be last directory name of the past you shared.
For example in path /home/to/path/workspace.
=========================
to mount permanently using fstab add this entry :
//192.168.122.1/workspace /home/gfuser/workspace/ cifs username=username,password=whatever_password,iocharset=utf8,sec=ntlm 0 0
then run ,
mount -a
