Note: By default, once you share the folder in virtualbox,you can access this folder in CentOS under  /media location but if you want to temporarily access with CentOS home folder , you need to mount the home folder with Ubuntu host  shared folder .I show on how to do it in below steps .

3) Create a folder in CentOS home and mount it  with the share folder.

"id" command will give the user id and group that we need to use in the next command. Use this info to execute the next command .

[orca@pygmy ~]$ sudo mount -t vboxsf -o uid=1000,gid=1000 CentOS_shared ~/Ubuntu_shared


This command will mount  "Ubuntu_shared"(CentOS home) folder  with "CentOS_shared" (Ubuntu host) . "uid" and "gid"
are the user id and group id value respectively.

Once you configured , "Ubuntu_shared" folder will be accessible  from  Ubuntu host folder "CentOS_shared"

Ubuntu shared folder 

Edit file in CentOs home folder

Edit the file

The file will be updated in Ubuntu host .

To make the folder in CentOS home permanently accessible, you need to configure "fstab"   which you can find on my other post .
