Expand the centos hard disk size in VirtualBox, virtualboxcentos
1. Clone an objectI created centos 6.3 During the previous installation, but I didn't have enough space to reinstall centos. I thought about using the resize command because I had to configure many things, however, when running D: \ Program Files \ Oracle \ VirtualBox> VBoxManage.exe modifyhd "D: \ CentOS 6.3.vdi" -- resize 12288 in win8, an error is always reported. The error is as follows: VBoxManage.exe: error: resize hard disk operation for this format is not impleme nted yet! No way. You can see it on the Internet. First, create an empty and large vdi on the virtual machine, and then use the clonehd command to clone it. Run the following command:
After that, mount the new vdi image to VirtualBox and start the new vdi file,Ii. Extended partitionsRun df-h to check whether the root directory is the same as the original one. Use LVM to expand the partition. LVM (Logic Volume Manager) logical management Volume

How can I change the disk space of a virtual machine in virtualbox?

Sun Virtualbox's simple way to increase the space of a virtual disk has recently encountered a problem. At the beginning of the creation of a virtual machine, we only allocated 10 Gb of C disk to install xp, which is not enough now. Virtualbox does not have the function of modifying the Virtual Disk size. Therefore, you have figured out the following steps: 1. Create a new virtual disk file, which is the size you need. For example, I create a new 30 GB 2. Set up the xp Virtual Machine in Virtualbox, And then mount a virtual disk image (my new 30 GB ). 3. Start the VM from the CD or iso, and use a winpe or a boot disk with the ghost tool. I used pe4. start ghost in pe and select disk to disk. During the cloning process, the new hard disk (30 GB) is smaller than the previous hard disk (10 Gb. Wait until the ghost is complete. 5. Remove the 10 Gb virtual disk from the xp Virtual setting, and keep the 30 GB one and set it as the first ide main channel.

A Simple Method for Sun Virtualbox to increase virtual disk space
Recently, when I first set up a virtual machine, I only allocated 10 Gb of C disk to install xp, which is not enough. Virtualbox does not have the function of modifying the Virtual Disk size. So I tried the following steps:
1. Create a new virtual disk file, which is the size you need. For example, if I create a 30G
2. Set the xp Virtual Machine in Virtualbox and mount a virtual disk image (my new 30 GB ).
3. Start the VM from the CD or iso, and use a winpe or a boot disk with the ghost tool. I use pe.
4. Start ghost in pe and select disk to disk. During the cloning process, the new hard disk (30 GB) is smaller than the previous hard disk (10 Gb. Wait until the ghost is complete.
5. Remove the 10 Gb virtual disk from the xp Virtual setting, and keep the 30 GB one and set it as the first ide main channel.
