by Keith Hurlic - - posted in linux, tech, xen

This blog post will show you how to delete the vm of your choosing and it’s primary disk from a Citrix Xen Server. A few things to keep in mind. Some of the disk will show up as xvda vs hda. This depends on how you have configured your server.

Virtual Block Device (VBD): A VBD is a software object that connects a VM to the VDI, which represents the contents of the virtual disk. The VBD has the attributes which tie the VDI to the VM (is it bootable, its read/write metrics, and so on), while the VDI has the information on the physical attributes of the virtual disk (which type of SR, whether the disk is shareable, whether the media is read/write or read only, and so on).

Virtual Disk Image (VDI): A VDI is a software object that represents the contents of the virtual disk seen by a VM, as opposed to the VBD, which is a connector object that ties a VM to the VDI. The VDI has the information on the physical attributes of the virtual disk (which type of SR, whether the disk is shareable, whether the media is read/write or read only, and so on), while the VBD has the attributes which tie the VDI to the VM (is it bootable, its read/write metrics, and so on).
