HP Integrity Virtual Machines Release Notes

10 Error Logging
This section contains information about the way Integrity VM logs messages.
10.1 Guest Log Can Grow Unbounded
The guest monitor log file (/var/opt/hpvm/guests/vm_name/log) records guest start and
stop information. These log files can grow very large. Use the hpvmconsole command
rec -rotate to close the current log file, rename it, and open a new one.
10.2 Log Messages Written to Old Log File
Log messages might be written to the command.log.old file instead of the command.log file.
If this is a problem, reboot the VM Host system. This reinitializes the log file for applications that
generate Integrity VM log messages to write to the current command.log file.
10.3 Saved MCA or INIT Register State Can Be Inaccurate
Virtual machines do not support standard management processor console errdump commands.
The virtual console's Virtual Machine menu provides the ed command for this purpose. The
options for a virtual machine are -mca and -init. When you examine the saved guest state
using the ed -mca or ed -init command, the preserved branch registers (B1-B5) do not always
contain accurate data.
10.4 Modifying the Size of the Monitor Log File
Integrity VM includes a monitor log (/var/opt/hpvm/common/hpvm_mon_log), which
captures the state of the VM Host. The size of the log file is determined by the VMMLOGSIZE
tunable, stored in the /etc/rc.config.d/hpvmconf file.
When the log file reaches VMMLOGSIZE, the current timestamp is appended to the name of the
log file and a new log file is opened. If you see many such files, increase the value of the
VMMLOGSIZE tunable. Do not set the value of the VMMLOGSIZE tunable below its 1024 KB
default.
10.5 Virtual Console Event Logs Different from Physical Machine Logs
The virtual console allows you to use the sl command to list the System Event log and the
Forward Progress log. The displays from the virtual console differ from those generated on a
physical machine in the following ways:
• Event numbering is inconsistent for different lines.
• Although the command menu allows you to specify a cell number, virtual machines are not
cellular. Therefore, this option is not functional.
