After adding the Hard disk to VMware/vSphere/vCenter it looks like this. In the vSphere Client inventory, right-click the virtual machine and select Edit Settings.Ĭomplete the wizard. Log into the vCenter Server using the vSphere Client. Run this below command and make note of the sdx entries, means list of existing hard disks.

For a full description of the utilities mentioned in this article, please refer to the manuals. We are assuming that you are already familiar with Linux system administration skills and having knowledge of vCenter Server or vSphere Client. Here are some steps for adding a new SCSI based virtual disk on a CentOS Linux virtual machine.

You should see the newly created unassigned free space.This article helps you to create and add a new virtual disk to an existing Linux virtual machine on VMware. Resize the disk to 12,000MB with the following command: VBoxManage.exe modifyhd "C:\Users\StephanA\VirtualBox VMs\Fedora_33\Fedora_33.vdi" -resize 12000īoot the virtual machine and open the Disks utility. If your host system is running Windows, open a command prompt and navigate to C:\Program Files\Oracle\VirtualBox. To increase the filesystem's space within the virtual machine, you must first increase the virtual hard drive on your host system. Luckily, I chose to use LVM, so I can easily fix this mishap.

Don't open the GNOME Software center or anything else that might download files from the internet in this condition.

A fresh installation with no additional software (except the VirtualBox Guest Additions) takes nearly the whole 8GB of available space. Then assign the downloaded Linux distribution image you want to install:Īs I mentioned, a disk space of 20GB is recommended, and 8GB is the absolute minimum for a Fedora 33 installation to boot up.

Click on the CD icon on the right, and select Choose a disk file…. Navigate to Storage and select the virtual optical drive.

Choose Host-only adapter for advanced security.

There is no internet nor physical network access for the guest. The host system can also connect to the guest system.

Host-only adapter: In this configuration, the guest system can only talk to the host or other guest systems running on the same host.

Choose Bridged adapter if you want to share the guest system's network services.

This setup is more flexible but requires more configuration. From the outside, it looks like there are two separate systems in the network, both sharing the same physical Ethernet adapter. Both systems will have independent IP addresses.

Bridged adapter: Here, the guest and the host system share the same physical Ethernet device.

Choose NAT if you only need internet access for the guest system.

(Although you could define port forwarding to access certain services.) When your host system has access to the internet, the guest system will have access, too. You are not able to access the guest system from within the host system over the network. From the outside, it looks like the host and the guest system use the same IP address.

NAT: The NAT adapter performs a network address translation.

You can create more than one network adapter. Now, open VirtualBox and click on the yellow New button: This allows you to increase the size of your guest system's hard drive if you are running out of space. LVM decouples the filesystem from the physical hard drives. You can even start a 64-bit OS image on a 32-bit host system (with limitations in memory usage, of course) and vice versa.Ĭonsiderations: If possible, choose a Linux distribution that comes with the Logical Volume Manager (LVM).

It does not matter if it's a 32-bit or 64-bit OS image.

Make sure that AMD-V or VT-x is enabled in the BIOS.ĭownload the image of the Linux distribution you want to try out.

The virtualization feature adds some additional CPU instructions, and it can be enabled or disabled in the BIOS. AMD calls it AMD-V, and Intel calls it VT-x. Almost every ordinary x86 CPU from the last decade comes which this feature. Hardware-assisted virtualization requires a compatible CPU. When we talk about virtualization, we actually mean hardware-assisted virtualization.
