| − | '''VMware''' is a proprietary virtualization brand. Their popularity is probably due to their early start in the field of virtualization and cross-platform host capabilities. [[VirtualBox]] and [[QEMU]] are [[free software]] alternatives to VMware.

| − | =Converting to VDI=
| |
| − | Follow the instructions in the [[VirtualBox#Converting_a_Flat_VMDK_to_a_VDI|VirtualBox article]] to convert a flat (raw) image into VirtualBox's virtual desktop image format.

| − | =Cracking Open VMDK Images with DD=
| |
| − | The <code>dd</code> utility can be used to crack open a <code>-flat.vmdk</code> file.
| |
| − | | |
| − | ==Offset and Length Information==
| |
| − | To get the offset and length of each partition, run the <code>file</code> command it.
| |
| − | | |
| − | <pre>
| |
| − | $ file Red\ Hat\ Enterprise\ Linux\ 4-flat.vmdk Red Hat Enterprise Linux 4-flat.vmdk: x86 boot sector; GRand Unified Bootloader, stage1 version 0x3, boot drive 0x80, 1st sector stage2 0xac03f, GRUB version 0.94; partition 1: ID=0x83, active, starthead 1, startsector 63, 5526297 sectors; partition 2: ID=0x82, starthead 0, startsector 5526360, 530145 sectors; partition 3: ID=0x83, starthead 0, startsector 6056505, 224910 sectors, code offset 0x48
| |
| − | </pre>

| − | If you're dealing with Linux partitions, look for IDs of 0x83. 0x82 is Linux swap. Partition one generally begins at offset 63, but in this example, you can see a second partition at offset 6056505. The sector sizes are in multiples of 512 bytes.

| − | ==Dumping the Partitions==
| |
| − | The key components of the <code>dd</code> command are the <code>skip</code> and <code>count</code> settings. They are, respectively, the offset and length of the data to copy, copied from the information given by the <code>file</code> command.
| |
| − | | |
| − | The following will dump the root partition.
| |
| − | <pre>
| |
| − | $ dd if=Red\ Hat\ Enterprise\ Linux\ 4-flat.vmdk of=~/centosroot.img skip=63 count=5526297
| |
| − | </pre>
| |
| − | | |
| − | The other partition in this example was the <code>/home</code> partition. Since it was at the end of the file, the <code>count</code> variable was left unspecified. The partition was extracted with the following line.
| |
| − | <pre>
| |
| − | $ dd if=Red\ Hat\ Enterprise\ Linux\ 4-flat.vmdk of=~/centoshome.img skip=6056505 bs=512
| |
| − | </pre>
| |
| − | | |
| − | ==Mounting the Partitions==
| |
| − | Mounting images on Linux is relatively straightforward.
| |
| − | | |
| − | <pre>
| |
| − | # mount -o loop /home/user/centosroot.img /mnt/mymountpoint
| |
| − | # mount -o loop /home/user/centoshome.img /mnt/mymountpoint/home
| |
| − | </pre>
| |
| − | | |
| − | You may need specify the filesystem type, i.e. <code>-t ext3</code>. Also, if you're having trouble mounting, it might be possible that you got the parameters wrong or potentially just got a bad copy. Try again to see if that's the case.
