Unable to allocate the I/O slot {0} for activation. This I/O slot is identified as a required adapter to activate this partition. Verify that the specified I/O is available to activate the partition. If it is not available, either create a new profile or modify the existing profile to identify the I/O adapter as a non-required resource, and then try to activate the partition again. If the partition must be activated with these resources, deactivate any running partition that is using the resource, and then try to activate this partition again.
