VDI or VHD?

[jnl2]

When building a VM, what are the benefits and drawbacks of configuring it to utilize a VDI or VHD?

Thank you.

I can't think of any valid reason to create a .vhd file rather than .vdi. Why are you considering it?

VDI is the native virtual disk format for Virtualbox, so VB will know how to use it best.

Virtualbox can use a VHD (Microsoft's virtual disk format). But VHD has a design flaw that puts important info about how to access the disk file at the end of the file, which info has to be moved if the disk file ever has to get bigger. That end-of-the-file data is prone to getting lost, thus killing the virtual disk.

Interesting.

Thank you.
