+# Error: "Internal error:xenopsd internal error: Storage_interface.Illegal_transition" in XenServer
+
+## Symptoms or Error
+
+After a failed “Move VM”, “Copy VM”, or “Export VM” operation, the Virtual Machine (VM) being operated cannot start. Following is the error message displayed:
+
+`User-added image`
+
+## Solution
+
+To resolve this error, complete the following procedure:
+
+Open the Console to the XenServer that is hosting the VM and run the following command:
+
+> list_domains
+
+All the VMs running on that server are displayed.
+
+Copy the UUID corresponding to id=0.
+
+This is the UUID of the Control Domain. The Control Domain is a privileged Virtual Machine that handles all hyper calls received from running VMs to perform all virtual tasks.
+
+Run the following command to obtain the UUID of the VBD (Virtual Block Device) object linking the Control Domain:
+
+> xe vbd-list vm-uuid=<uuid of the Control Domain>
+
+Run the following commands to unplug and destroy the VBD:
+
+> xe vbd-unplug uuid=<uuid of the vbd>
+
+> xe vbd-destroy uuid=<uuid of the vbd>
+
+## Make a local iso repository
+
+> xe sr-create name-label=LocalISO type=iso device-config:location=/var/opt/xen/ISO_Store device-config:legacy_mode=true content-type=iso
+
+This creates a UUID for the new directory:
+
+`e94e25bb-bcdc-801b-b62a-b51b686a3bdc`
+
+# Import
+
+xe vm-import filename=/mnt/blah.xva
+
+
+# USB
+
+## Attack
+
+Put in the USB.
+
+Get the USB's uuid.
+
+> xe pusb-list
+
+Make the USB recognised as a device.
+
+> xe pusb-param-set uuid=<uuid>
+
+For passthrough, use this:
+
+> xe pusb-param-set uuid=<uuid> passthrough-enabled=true
+
+## Attach to host

+(requires reboot of guest)
