Description<\/strong><\/p>\n\n\n\n Virtual Hard Disk<\/strong> (VHD<\/strong>) is a disk image file format which represents a virtual hard disk drive, capable of storing the complete contents of a physical hard drive. <\/p>\n\n\n\n It\u2019s a container file that acts similar to a physical hard drive. <\/p>\n\n\n\n The disk image replicates an existing hard drive and includes all data and structural features. <\/p>\n\n\n\n Just like a physical hard drive, a VHD<\/strong> can contains a file system, and you can use it to store and run an operating system, applications, as well as store data. <\/p>\n\n\n\n One of the typical uses of VHDs<\/strong> in VirtualBox Virtual Machines (VMs) to store operating systems and application, and data. <\/p>\n\n\n\n In this article, we will demonstrate how to create a virtual hard disk volume using a file in Linux. <\/p>\n\n\n\n For the purpose of this guide, we will create a VHD volume of size 1GB<\/strong>, and format it with EXT4<\/strong> file system type. <\/p>\n\n\n\n Create a New Image to Hold Virtual Drive Volume<\/strong><\/p>\n\n\n\n There are number of ways you can do this, but the most easiest way is using the following dd command<\/strong>. <\/p>\n\n\n\n In this example, we will be creating a VHD volume of size 1GB<\/strong> image.<\/p>\n\n\n\n Where: <\/p>\n\n\n\n We need to format the EXT4<\/strong> file system type in the VHD<\/strong> image file with the mkfs utility<\/strong>. <\/p>\n\n\n\n Answer In order to access the VHD<\/strong> volume, we need to mount to a directory (mount point). <\/p>\n\n\n\n Run these commands to create the mount point and mount the VHD volume, respectively. <\/p>\n\n\n\n The Note<\/strong>: The VHD<\/strong> filesystem will only remain mounted until the next reboot, to mount it at system boot, add this entry in the \/etc\/fstab<\/strong> file.<\/p>\n\n\n\n Now you can verify the newly created VHD filesystem with mount point using the following df command<\/a><\/p>\n\n\n\n Removing Virtual Drive Volume<\/strong> If you don\u2019t need the VHD volume anymore, run the following commands to unmount the VHD filesystem, then delete the image file:y<\/code>, when prompted that \/media\/VHD.img<\/strong> is not a block special device<\/p>\n\n\n\nsudo mkfs -t ext4 \/media\/VHD.img<\/em><\/strong>
<\/pre>\n\n\n\n-o<\/code> is used to specify options for mounting, here, the option loop indicates the device node under the \/dev\/<\/strong> directory.<\/p>\n\n\n\nsudo mkdir \/mnt\/VHD\/<\/em><\/strong>
sudo mount -t auto -o loop \/media\/VHD.img \/mnt\/VHD\/ <\/em><\/strong>
