How to share and mount temporary folder in CentOS home and Ubuntu host in Virtualbox .

  In this post , I'm going to share on how to share and mount temporary folder in CentOS home and Ubuntu host in Virtualbox .

What will this tutorial covered.

1) Create a folder and Configure Virtualbox in Ubuntu host .
2) Share and edit a file between Ubuntu Host and CentOS.
3) Create a folder in CentOS home and mount it  with Ubuntu host shared folder.

Steps

1) Create a folder and Configure Virtualbox in  Ubuntu host.

1.1) Create a shared folder in Ubuntu host system.

Create a folder 

I named the folder "CentOS_shared" .

1.2) Open Virtualbox go to  "Settings> Shared folders" . Add the newly created folder in Step 1.1 . Click the "blue plus" sign to look for the folder .

1.4) Click "Auto-Mount"  box.

1.5) Click "OK" .

1.6) Run  CentOS in Virtualbox. By click the "Start" button .

2) Share and edit a file between Ubuntu Host and CentOS.

2.1) By default, the shared folder is mount under "/media" in CentOS.

/media

the shared folder in CentOS is under "/media/sf_CentOS_shared"

2.2) Create and edit a file between Ubuntu host and CentOS .

Create a file in Ubuntu host

Edit the file details

Check the edited file in CentOS

/media/sf_CentOS_shared

Check the file 

Edit the file

Check the edited file in Ubuntu host .

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.

3.1) Create a folder  in CentOS home . In this example, i create a folder name "Ubuntu_shared" .

Create a new folder in  CentOS home

3.2 ) Mount the folder  with the ubuntu host folder . Open terminal and run below command .

[orca@pygmy ~]$ id uid=1000(orca) gid=1000(orca) groups=1000(orca),10(wheel),991(vboxsf) context=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023 [orca@pygmy ~]$

"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 .
