VirtualBox is a great free virtualization software from Oracle. I’ve previously written many articles on VirtualBox, including how to and how to.If you’ve had any experience with virtualization software, you’ve probably also heard of VMWare and Hyper-V. I’ve previously used Hyper-V from Microsoft for and one feature that I really liked was the ability to easily share files and folders between the guest and host operating system.In VMWare and Hyper-V, all you have to do in order to share files from the host OS to the guest OS is drag and drop between the desktops. When I switched over to VirtualBox, I realized that sharing folders in VirtualBox was not as simple as dragging and dropping.This was really annoying to me at first and it took me a little while to figure out exactly how to do it! In this article, I will walk you through the steps for sharing folders between guest and host OS in VirtualBox.
Share Between Guest and Host in VirtualBoxFirst, you have to install VirtualBox Guest Additions in the guest OS. You can do this by going to Devices and clicking on Install Guest Additions CD image. Once installed and your guest OS rebooted, you need to create a virtual shared folder. You can do this by going to Devices again and clicking on Shared Folders – Shared Folders Settings.Now click on the Add New Shared Folder button on the right.In the Folder Path box, click the down arrow and then click Other. Browse to the folder on the host OS that you would like to share with the guest OS.
In the Folder Name box, give your share a name. You can choose to make it read-only, auto-mount the folder after restarts, and make the shared folder permanent.Click OK and the new shared folder will show up under Machine Folders if you chose to make it Permanent, otherwise it will show under Transient Folders.Now click OK to close the Shared Folders dialog. You have to do one more thing in order to be able to actually access the folder on the host OS. Depending on whether the guest OS is running Windows or Linux (Ubuntu, etc), the method is different.
Windows GuestIn this case, you can either browse to the shared folder by going to Computer – Network – VBOXSVR or you can map a drive letter to that shared folder.I prefer the second method to make it easily accessible. The easiest way to map the folder to a drive letter on the virtual PC is to simply right-click on the folder as shown above and choose Map Network Drive.Pick a drive letter, make sure Reconnect at login is checked and then click the Finish button.You can also map the network drive using the command prompt, if required. To do this, open a command prompt and type in the command below. Net use z:Simply replace sharename with the Folder Name you used when adding a share. Note that you do NOT need to change vboxsvr.
Also, you can use any letter that is currently free; it doesn’t have to be Z if you don’t want. You should get a message like The command completed successfully as shown below.Now when you go to Explorer or My Computer, you’ll see the new drive mounted and ready for access!Linux GuestTo mount a shared folder in a Linux Guest OS such as Ubuntu, type in the following command in terminal: mount -t vboxsf -o OPTIONS sharename mountpointReplace sharename with the name of the share and mountpoint with the path where you want the share to be mounted (i.e. /mnt/share).Not too hard eh? Of course, if you didn’t know you had to do all this, it could get quite frustrating! Now when you need to share files or folders in VirtualBox, you’ll be able to do it easily.

This tip will show how it is easy to deploy a guest cluster using the shared virtual hard disk feature of Hyper-V 2012 R2.VMs that are going to be part of the guest cluster must have Windows Server 2012 or later OS installed. These VMs must be running on a Hyper-V 2012 R2 or later host.
There are three different partition schemes that Mac OS X supports: Apple Partition Scheme. This scheme is used by PowerPC Apple Mac computers. GUID Partition Scheme. This scheme is used by Intel Macs. Master Boot Record: This is the scheme that Windows and DOS uses. May 20, 2019 - Apple supports three different partition schemes: GUID Partition. GUID Partition Table: Used for startup and non-startup disks with any Mac.

If you are planning to use Windows Server 2012 as a guest OS, make sure to upgrade Integration Services to version.Virtual hard disks you are going to share between multiple VMs must be placed either on a cluster configured on a block-level storage or a Scale-Out-File Server cluster configured on a file-based storage. If you try to enable sharing for a that is not placed on either of those, you will see an error message as shown Figure 1.
Hyper V Guest Clustering 2016
Error message. As indicated in Figure 1, the virtual hard disk you are going to enable the sharing for is stored on a location that is not supported by the Shared Virtual Hard Disk feature. Before you enable sharing on a virtual hard disk, Hyper-V checks the underlying storage to ensure it supports the SCSI Persistent Reservation (PR) commands. A PR is a command that is used by the clustering to protect disks. When a disk is reserved, no other computers are allowed to access the disk. This is the basic functionality that Hyper-V would expect from the underlying storage before the sharing can be enabled.
Vhd Sets Vs Shared Vhdx
This is only possible if you implement shared storage.As for using the shared virtual hard disk feature, the whole process is simple. All you need to do is create the VMs that are going to be part of the guest cluster, store VM configuration and virtual hard disk files to a shared storage location, enable virtual hard disk sharing on the property page of the VMs, verify sharing is enabled on virtual hard disks for all VMs and then build the guest cluster by installing the failover cluster feature inside the VMs.

Step 1: Creating VMs and assigning path to virtual hard disksWhen creating VMs, make sure to specify the location for storing the VM configuration and virtual hard disk files as listed below:. In case of a CSV cluster, specify C:ClusterStorageVolumeX where X represents the CSV volume number.
In case of a Scale-Out-File Server cluster, use ServerNameShareName as the path for storing VM configuration and virtual hard disk files.It is recommended to create at least two virtual hard disks; one for installing the guest operating system and a second hard disk that will be shared between the VMs. The OS virtual hard disk can be either in VHD or VHDX format, but the data virtual hard disk that is going to be shared between multiple VMs must be in. When creating the second virtual hard disk, make sure to attach VHDX to a virtual SCSI controller on all VMs that are going to be part of the guest cluster. This is because Hyper-V uses SCSI persistent reservation commands to enable sharing of a virtual hard disk between multiple VMs.
Step 2: Enabling Virtual Hard Disk SharingHyper-V must be told to allow sharing of a virtual hard disk between multiple VMs and that is done by enabling a checkbox on the property page of VMs. To, go the property of a VM and under SCSI controller, expand the that you created and then go to Advanced Features. In the details pane, select 'Enable virtual hard disk sharing' check box as shown in Figure 2 below and then hit 'Apply.' Enable virtual hard disk sharing. Step 3: Attaching and enabling virtual hard disk sharing for remaining VMsAt this step, you are required to attach the VHDX file to a SCSI virtual controller on the remaining VMs and then select the 'Enable virtual hard disk sharing' option.
