|
|
|
|
If the graphical consoles VNC and SPICE are disabled, the
|
|
live-migration of an instance will result in an ERROR state.
|
|
VNC and SPICE are usually disabled on IBM z systems platforms
|
|
where graphical consoles are not available. The serial console
|
|
is then enabled and VNC + SPICE are disabled.
|
|
|
|
The error will be raised at
