Basic VM Management

xe vm-list

Start, stop, et c. with xe:

xe vm-start vm=$TARGET_VM

xe vm-shutdown vm=$TARGET_VM

Destruction requires the uuid.

xe vm-destroy uuid=$TARGET_UUID

Autocompletion works well with all of these commands.

Shut Down VM

List VMs.

xe host-list

xe vm-list resident-on=$HOST_UUID

xe vm-shutdown uuid=TARGET_VM force=true

If this doesn't work, try:

xe vm-reset-powerstate uuid=TARGET_VM force=true

Get the id:

list_domains

And destroy the domain:

/opt/xensource/debug/xenops destroy_domain -domid $DOM_ID

Problem Solving

Error: Internal error:xenopsd internal error: Storage_interface.Illegal_transition in XenServer

After a failed “Move VM”, “Copy VM”, or “Export VM” operation, the Virtual Machine (VM) being operated cannot start.

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=$CONTROL_DOMAIN_UUID

Run the following commands to unplug and destroy the VBD:

xe vbd-unplug uuid=$VBD_UUID

xe vbd-destroy uuid=$VBD_UUID

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, e.g.:

e94e25bb-bcdc-801b-b62a-b51b686a3bdc

Import

xe vm-import filename="$FILENAME".xva

USB

Attach

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)

Storage Spaces - "SR"

Exporting and Exporting VMs

xe vm-export vm=$VM_NAME filename="$FULL_PATH".xva

xe vm-import vm=*<Name>* filename="$FULL_PATH".xva
