When running Oracle Solaris 10 in a guest domain, this message appears on the guest domain console upon start up:
Boot device: disk File and args: -k Loading kmdb... SunOS Release 5.10 Version Generic_150400-20 64-bit Copyright (c) 1983, 2014, Oracle and/or its affiliates. All rights reserved. WARNING: sun4v_pcbe_enable: no HV API found Hostname: ...
This message appears because the Oracle Solaris 10 version of cpustat(1M), and other similar commands, cannot monitor the performance counters in the SPARC S7 processor.
Starting with Oracle Solaris 11.3, the cpustat(1M) command can monitor the performance counters in SPARC M7 and S7 processors.
