However now it is not supported and prints error. I checked

so chaning the base to 0 to make it supporting other formats.

We assumed io_channel allocation always succeeds, but
that's not true. Doing I/O to any vhost session that
failed to allocate an io_channel would most likely
cause a crash.
We'll now detect io_channel allocation failure and
print a proper error message. The SCSI target for
which the channel allocation failed simply won't be
visible to the vhost master. All I/O to that target
will be rejected.
We should probably report the error to the upper
layer and either prevent the device from starting
or fail the SCSI target hotplug request. But for now
let's just prevent the crash.
