Virtual Machine Powers Off if Attempting to Connect SCSI Device in a Powered On Virtual Machine
Details
Why does my virtual machine power off when I try to connect to
a SCSI device in a powered-on virtual machine?
Solution
If you try to connect a SCSI device on a powered-on virtual
machine, the virtual machine will power off. This is because the
connect/disconnect operations are not supported by the backend for
SCSI devices.
Workaround: None. SCSI devices should not be connected or
disconnected on a powered-on virtual machine.
