The following covers the essential steps to implement Oracle VirtualBox on a Windows system.
For optimal performance of your VMs:
- Ensure your bios is set to enable VT (Virtualization Technology).
- Set Power Options to use the (x) High performance power plan.
- Use Fixed disks for your VMs as opposed to Dynamic.
- Ensure your virus scan software excludes your VirtualBox directories.
- Use the baseline settings in your VM's shown here.
- With no VMs active, defrag the drive with your VMs.
Use Defraggler by Piriform\Ccleaner. It is much better than Windows defrag!
If your system is still slow after the above try this.

VM OS Installation
- Select the Start button.
- Follow normal OS installation.
- OS install cheat sheets if required.
Install Guest Additions
Linux 8.5 or later
0. Make sure in Settings\General: Advanced -> Shared Clipboard = Bidirectional 1. Update Linux yum repolist yum search release-el8 yum update -y 2. Reboot. 3. yum -y install kernel-uek-devel-`uname -r` 4. Unmount any .iso disks. 5. Mount\run the latest Guest Additions version .iso (ex: 6.1.32).
DL latest Guest Additions. 6.1.32 example here.
For Oracle Linux 8.x make sure to install zlib and elfutils:
From Devices, remount the OL8 .iso. As root, cd /run/media/root/OL-8-1-0-BaseOS-x86_64/BaseOS/Packages rpm –ivh zlib-devel-1.2.11-10.el8.x86 64.rpm rpm-ivh elfutils-libelf-devel-0.176-5.el8.x86_64.rpm OR yum install zlib-devel yum install elfutils-libelf-devel For 8.4 and Later Also Do this: yum -y install gcc make yum -y install kernel-uek-devel-`uname -r` From Devices, unmount the OL8 .iso.
More details on this here .
1. Start VM on LINUX and login as root (on Windows login as Administrator). 2. From vbox menu: - Select: Devices - Select: Optical Drive - Choose disk image: VBoxGuestAdditions_6.x.x.iso 3. Run install for Guest Editions from mounted .iso drive (if does not auto-run). - Accept defaults. - Process runs. - Restart VM\OS when done.
On LINUX systems you should see a shortcut on the desktop for each shared folder.
Ubuntu: Guest Editions - Manually Installing

Create a Shared Folder
- Ensure the dir to share exists on host systems hard drive.
- Example: C:\software
- Go to: Settings -> Shared Folders
- Select Add Folder button on right.
- Select host folder: C:\software
- Folder name: software
- ☐ Read-only
- ☑ Auto-mount
Create ifg File
- cd to /etc/sysconfig/network-scripts
- vi ifcfg-<InterfaceMatchingMAC> and Set Values
DEVICE=enp0s9 BOOTPROTO=none ONBOOT=yes PREFIX=24 IPADDR=192.168.1.50
Add new IP to hosts file. Example:
If need be, set system hostname using: hostnamectl set-hostname <hostname>
Create Virtual Machine for ASM (RHEL7 Example)
Change as needed for your testing environment.
Configure Core VM
- Select New toolbar button.
- Name and Operating System
- Name: [MyOSName]
- Type: Linux
- Version: Red Hat (64-bit)
- Memory Size At least 1024mb
- Hard Drive
- (x) Create a virtual hard drive now.
- Hard Drive File Type
- (x) VDI
- Storage On Physical Hard Disk
- Fixed Size
- File Location and Size
Create Shared Disk
Create Disks for ASM Groups: GRID, DATA and FRA.
A useful shared disk convention is:
D:\VirtualBoxes\zShared\RAC1_ASM_GRID.vdi 55g D:\VirtualBoxes\zShared\RAC1_ASM_DATA.vdi 20g D:\VirtualBoxes\zShared\RAC1_ASM_FRA.vdi 20g
Then for each test RAC just change\increment RAC1_. Ex: RAC2_
File 🠊 Virtual Media Manager [Create] (x) VDI (x) Fixed size File location and size <Path>\ASM_GRID.vdi 55.00 GB [Create] [Create] (x) VDI (x) Fixed size File location and size <Path>\ASM_DATA.vdi 20.00 GB [Create] [Create] (x) VDI (x) Fixed size File location and size <Path>\ASM_FRA.vdi 20.00 GB [Create]
Disks must be Fixed (not Dynamic) to be shareable.
Make Disks Sharable
File 🠊 Virtual Media Manager Type: Sharable
Attach New Disks to Node 1 VM
Select VBox [Settings] 🠊 [Storage] 🠊 Controller: SATA [Add Hard Disk] Select: ASM_GRID.vdi [Choose] Add Hard Disk Select: ASM_DATA.vdi [Choose] Add Hard Disk Select: ASM_FRA.vdi [Choose] [OK]
After above completed, Add disks to other nodes\VMs.
RAD Vbox Backup\Restore
This is not a supported way to save/restore images in VirtualBox, but it is very simple and worked well. The restore is limited to the VirtualBox setup where images were saved.
Stop both VMs. Find the location where VB stores images: Main menu | File | Preferences | General, "Default Machine Folder" box. For example: "C:\Users\scott\VirtualBox VMs". Go to this folder and locate "rac1", "rac2" directories and "rac_shared_disk1.vdi" file. Make a .zip or .rar file containing these three items. If you don't have compressing tools and there is enough disk space, you can copy these three items to another location. The images are saved!
In order to restore these images:
- Make sure VMs are stopped.
- Go to the "VirtualBox VMs" folder and delete "rac1", "rac2" directories, and "rac_shared_disk1.vdi" files.
- Restore these three items from the .zip file or copy from the location where these items were saved
The restored VMs are ready to run.

Baseline VirtualBox Defaults
• Advanced: Shared Clipboard: Bidirectional
• Base Memory: 4096mb (minimum for RAC 9216mb). • ☐ Floppy (disable) • Pointing Device: USB Tablet (to fix bug where mouse disappears) • Processors: 2 (minimum for RAC 4). • Acceleration -> Paravirtualization Interface: If Windows 7 host: None If Windows 10 host: Default (with VBox 6.1.0 or later) - If create DB (via dbca) takes excessive time try setting this to None. - Monitor CPUs too (increase if required). - Also for SGA/PGA try: 1536m\256m as minimums.
• Video Memory: 128mb
• Enable the acceleration options possible (3D Acceleration etc.).
• Controller: IDE -> Optical Drive: -> <Choose Linux ISO for Install> • Controller: SATA: If Windows 7 Host: ☑ Use Host I/O Cache If Windows 10 Host: ☐ Use Host I/O Cache ==> HUGE Performance bug in 5.2x if enabled!
• D:\software: ☑ Auto-mount
Interfaces for RAC
- Adapters 1 & 2 used for local and Internet connectivity.
- Adapters 3 & 4 used for RAC.
Settings -> Network
[x] Enable Network Adapter Attached to: NAT
[x] Enable Network Adapter Attached to: Host-only Adapter Promiscuous Mode: Allow All
[x] Enable Network Adapter Attached to: Internal Network Name: pubnet Promiscuous Mode: Allow All
[x] Enable Network Adapter Attached to: Internal Network Name: privnet Promiscuous Mode: Allow All
Note the MAC addresses - they will be needed in OS install.
Disable Power Saving (screen saver)
Applications -> System Tools -> Settings Power -> Blank screen: Never
Disable Screen Locking
Applications -> System Tools -> Settings Privacy -> Screen Lock -> Automatic Screen Lock: OFF
- Baseline VM settings in place. - OS Software Updated. - .bashrc Common Aliases set. - initLnxForOra.sh (12.2.x) run. - Oracle's Preinstallation rpm installed. - Logged into GUI as root, grid and oracle. -- Disabled screen saver. -- Disabled screen locking. - Additional rpms installed: cvuqdisk-1.0.9-1,Flash, rlwrap, dconf-editor. - gnome, Changed default app settings (gedit, nautilus).
Network Interface Change Bug
From GUI: Applications -> System Tools -> Settings -> Network
If you to change a network interface IP and do not need a Gateway:
- You may need to put in a bogus Gateway address (0.0.0.0) to be able to hit Apply.
- Then after you save it, turn the interface Off then On to bind it.
Network, Stopping Excessive Outbound Traffic
If excessive data is being sent from a VM and you do not require constant connection to the Internet or a Host-only Adapter, this can be remedied by disabling the NAT adapter. You can re-enable it at times when you need to update the OS\packages or make other connections to the Internet.
Disabling your NAT interface under most conditions should not interfere with any VBox-to-VBox connections (like for RAC or Data Guard).
If your host system is Windows you can easily validate how much data is being sent by:
- Run the Task Manager.
- Select the Performance tab.
- Select Ethernet.
- Observe the Send and Receive kps.
The Send Kps should generally be less than 100 if not tending to be 0 (zero).
Enable High Performance
This snippet came from this link.
Windows 10 Pro users can lock in the power plan using Group Policy Editor
First set the power plan, but don't reboot right away.
To do this, run CMD prompt as admin In the command prompt, type
powercfg –restoredefaultschemes and press Enter.
Go to Control Panel > Power Options and select High Performance from Control Panel > Power Options, but do not reboot the PC yet.
Make whatever custom changes you want to your High Performance plan using Change plan settings > Change advanced power settings, but still do not reboot the PC yet.
Now from the taskbar search type gpedit.msc and run as admin. This opens Group Policy Editor
Navigate to Computer Configuration -> Administrative Templates -> System -> Power Management
In the right hand pane double click on "Select an active power plan" In the window that pops up select "Enabled" This will allow you to then select "High Performance" from the drop down menu Select Apply and OK to close out Now reboot the PC.
When you go to Control Panel > Power Options it will say "Some settings are managed by your system administrator", with the options below that grayed out. But you should be able to see below that it's set at High Performance, even though the option to change settings will be grayed out as it's now handled by Group Policy Editor.
Get VirtualBox Version
Guest Editions Version
lsmod | grep vboxguest
You can also use this to see if the Guest Editions has been installed.
Window Position Setting
- Set global settings from here: File 🠊 Display: Width and Height
Values written here: C:\Users\<UserName>\.VirtualBox\VirtualBox.xml
VM Instance Values
- The values are stored in your VirtualBox dir <VMname>.vbox
- Value: <ExtraData><ExtraDataItem name="GUI/LastNormalWindowPosition"
value="<Absolute upper-left X>,<Absolute upper-left Y>,800,642"
- Value: <ExtraData><ExtraDataItem name="GUI/LastNormalWindowPosition"
<ExtraDataItem name="GUI/LastNormalWindowPosition" value="11,36,800,642"/>
<ExtraDataItem name="GUI/LastNormalWindowPosition" value="988,25,800,642"/>
- If values set to invalid values they may be changed.
- X=Horizontal - Y=Vertical
VBoxManage Session Example
cd C:\Program Files\Oracle\VirtualBox VBoxManage setextradata zLnx01 GUI/LastNormalWindowPosition 11,36,800,642 VBoxManage setextradata zLnx02 GUI/LastNormalWindowPosition 929,36,800,642 VBoxManage setextradata zLnx01 GUI/LastGuestSizeHint 11,36,800,642 VBoxManage setextradata zLnx02 GUI/LastGuestSizeHint 929,36,800,642
You might also need to manually move the VM window to have it detect a change and set flag. THEN run VBoxManage. Crazy!
Resize VBox & Linux Disk\Partition: GUI
Disk must be created as Dynamically allocated to use this option to resize.
- Create VM. - From VM Create a new disk to attached to this VM. -- File -> Virtual Media Manager [Create] (x) VDI (x) Dynamiclly allocated Location: D:\VirtualBoxes\Shared\data01.vdi 1.00 GB [Create] -- Select: VBox VM -> Storage -> Controller: SATA -> Add Hard disk Scroll down to "Not Attached" and select and [Choose] [OK]
- Start Linux OS and login as root. - Create LINUX disk partition for newly added disk. -- Confirm new disk attached and correct size: lsblk -- Partition disk: fdisk /dev/sdb -- Confirm new partition and size: lsblk - Shutdown Linux OS
Resize VMWare Disk
- File -> Virtual Media Manager - Select Disk - Increase the value of Size. Ex: If 1.00 GB set to 2.00 GB [Apply]
Resize Linux Partition
From this point you can use parted and resizepart cmd.
