Today I needed to play around work out something on RHEL and OpenSolaris. I have both systems running in a VirtualBox on my Mac and because of the latest update to VirtualBox I was supposed to update also the so called Guest Additions on RHEL and OpenSolaris. This is unofficial version of Guest Additions for Mac OS X Guest (10.5 and above) In order to avoid kernel panic or some random errors like 'still waiting for root device' or something else, Try to close all applications or something else.

In the guest Mac, open the Terminal and go for a reboot on the Recovery partition; sudo nvram 'recovery-boot-mode=unused' sudo reboot Now you're in Recovery mode, enter the Terminal and do: csrutil disable sudo spctl kext-consent add VB5E2TV963 nvram -d recovery-boot-mode reboot Back in 'normal' mode, open the Terminal, and do.
I use VirtualBox on my Mac for “other” operating systems.
I was recently creating a new Ubuntu guest OS for doing some work with PostgreSQL on Linux. I like a GUI, so I was using pgAdmin. Normally I don’t care if the window is 800×600, but when I started using pgAdmin, I couldn’t see all of the window.

Support for COM add-ins that use custom ribbon controls: Available: Office 2016 for Mac doesn't support third-party COM add-ins.
I first tried the System->Preferences->Monitors in the Ubuntu guest. But that was a dead end.
Then I tried finding something in VirtualBox that would allow me to increase the virtual monitor size. I found out that there is a VirtualBox Guest Additions image within the VirtualBox installation. It’s called VBoxGuestAdditions.iso. I could see it listed in File->Virtual Media Manager->CD/DVD Images.
But I couldn’t view it as a CD-ROM within Ubuntu. When I clicked the CD-ROM icon on the bottom of the guest OS window, it wasn’t listed. Also, I couldn’t navigate to the .iso.
All I had to do was mount it as a CD-ROM for the guest OS and then install it. I know where it is, it’s in the VirtualBox application folder.
Except… on Mac, the contents of an Application folder aren’t navigable by default. It’s treated as a monolith for file/folder purposes. To get around this, I just navigated to my home directory (~) and created a quick soft link to the folder containing the VBoxGuestAdditions.iso.
$ cd ~
$ ln -s /Applications/VirtualBox.app/Contents/MacOS VBoxAddons
Now I could navigate to the .iso by clicking the CD-ROM on the bottom of the VirtualBox guest OS window, and choosing Choose a virtual CD/DVD disk file…. Then I just navigated to my home directory and clicked the soft link folder to view it’s contents.
Inside I selected the VBGuestAdditions.iso.
Now I can select the VBGuestAdditions.iso from the CD-ROM menu on the bottom of the VirtualBox guest OS window.
For me, this mounted as /media/VBOXADDITIONS_4.0.4_70112
All I had to do was run
$ sudo /media/VBOXADDITIONS_4.0.4_70112/VBoxLinuxAdditions.run

When that finished I restarted Ubuntu.
Now I’ve got a nice big 1024×768 Ubuntu window.

Share files between two SO is easy because there are different protocols for sharing resources (NFS, CIFS/SMB/Samba, FTP, …), but sharing files between two PCs with OS Linux based, and one of them as VM guest of another one is a bit more complicated. Here’s how to do it when we Mac OSX as HOST and CentOS as GUEST:
Steps
Mount DVD ISO image in CentOS VirtualBox guest
- Previously, I have download DVD ISO image, then I have copied to my Mac OSX Host.
- From Virtual Box menu, goes to Devices > CD/DVD Devices and mount selecting CentOS’s DVD ISO image (ISO previuosly added to VBox’s “Virtual Media Manager”).
- In CentOS guest now you can see DVD iso mounted as
/media/CentOS_5.5_Final
. - You can install packages directly off the mounted DVD ISO. Now, modify
/etc/yum.repos.d/CentOS-Media.repo
file, enter: - Make sure enabled is set to 1:
- Save and close the file. To install packages from only DVD media repo, do this: Notes:
- –disablerepo=*: disable all yum repo
- -y: assume yes to any question which would be asked
- –enablerepo=c5-media: enable c5-media repo
Install Virtual Box Additions in CentOS guest
Before anything, It is necessary install some packages as compiler gcc, kernel libs and sources.
- Install the following packages with CentOS DVD ISO image mounted:
- Unmount CentOS DVD ISO image and mount Virtual Box Guest Additions in your CentOS guest:
- Restart CentOS guest
- Now, install VBoxGuestAdditions in CentOS guest:
- Restart CentOS guest again.
- Now you could use special functionalities as resize the guest windows, share files, etc…
Share files beetwen Mac OS X as Host and CentOS as Guest
- In your Host Linux box:
- In main menu of your Linux Guest’s Virtual Box:
- Go to
Devices > Shared Folders
… - In popup, add shared folder and select Host’s folder (
/Users/chilcano/files2share
), set up a name asfiles2share
and make permanent.
- Go to
- In your Guest Linux box opens a terminal window and create a new directory where you’ll mount shared folder
- In this terminal, enter the id command and look the output. We will use uid and gid:
- Now, we will mount shared folder from Host to Guest. From terminal in Guest Linux:
Make the Mounted Share permanent
You can make the shared folder mount automatically each time you start the CentOS guest by making an entry in
/etc/fstab
.- From the CentOS guest edit fstab:
- Add a line at the bottom of file, and that looks like this:
- Verify mounted folder: In Mac OS X (host):
In CentOS (guest):
