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) cannot monitor the performance counters in the SPARC T7 and M7 processors. This message may be safely ignored.
Starting with Oracle Solaris 11.3, the cpustat(1M) command can monitor the performance counters in SPARC T7 and M7 processors.
