Basic VM Management

xe vm-list

Start, stop, et c. all done with xe:

xe vm-start vm=TTS

xe vm-shutdown vm=Bob

Destruction requires the uuid.

xe vm-destroy uuid=243b1165-14aa-37f6-496f-44879d05b3f2

Shut Down VM

List VMs.

xe host-list

xe vm-list resident-on=<uuid_of_host>

xe vm-shutdown uuid=<UUID from step 3> force=true

If this doesn't work, try:

xe vm-reset-powerstate uuid=<UUID from step 3> force=true

Get the id:

list_domains

And destroy the domain:

/opt/xensource/debug/xenops destroy_domain -domid <DOMID from step 7>

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=

Run the following commands to unplug and destroy the VBD:

xe vbd-unplug uuid=

xe vbd-destroy 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:

e94e25bb-bcdc-801b-b62a-b51b686a3bdc

Import

xe vm-import filename=/mnt/blah.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=

For passthrough, use this:

xe pusb-param-set uuid= passthrough-enabled=true

Attach to host

(requires reboot of guest)
