The following sections describe release notes for Linux guests.
Linux Guest Installation Errors |
 |
The first time you install the Linux guest management software, the following error may occur:
=== from /var/log/messages file ===
Jan 18 22:45:00 lsn0000 kernel: ipmi_si: Error clearing flags: c1
=== from "dmesg" command ===
ipmi_si: Error clearing flags: c1 |
You can ignore this error message.
Linux Guests with FC Tapes Display Errors |
|
MPT errors may appear while booting a Linux guest if FC tapes are attached to it. FC tape devices return EIO on device reset, which causes timeout of the MPT reset. The boot proceeds after the reset timeouts; these errors can be ignored. For example:
Use ^ and v to change option(s). Use Enter to select an option

Welcome to Red Hat Enterprise Linux AS |
Disable IPv6 on Linux Guests |
|
Integrity VM does not support IPv6 on guests. Linux Redhat enables IPv6 by default. When the Linux guest boots, the following message is displayed:
printk: 1 message suppressed |
This message indicates an issue in the IPv6 DAD (Duplicate Address Detect) mechanism and is harmless. You can ignore this message, or you can disable it by including the following line in the/etc/modprobe.conf file:
Preparing Linux Guests for VM Manager |
|
If Linux guests are to be managed by VM Manager:
Install the tog-pegasus package.
On Red Hat Enterprise Linux, modify the file /etc/Pegasus/access.conf to allow WBEM access using your designated WBEM user name and password. Follow the steps below to configure this file. In this example, your designated WBEM user name is assumed to be wbemuser.
Look for the following line in this file:
-: ALL EXCEPT pegasus:wbemNetwork |
Change this line to either of the following options:
# Allow access only from user 'wbemuser':
-: ALL EXCEPT wbemuser pegasus:wbemNetwork
|
# Allow access by all users:
+: ALL EXCEPT :wbemNetwork |
Start the tog-pegasus package by executing the following command:
# /etc/init.d/tog-pegasus start |
For information on where to download the Utilization Provider for the Linux guest, see the VSE Management Software Installation and Update Guide.
IPv6 Dynamic Address Resolution is Broken in Linux |
|
Linux guests report messages such as printk: 1 message suppressed on a regular basis on the console. To prevent these messages, add the following line to the file/etc/modprobe.conf:
alias net-pf-10 off
Infrequent “Ooops: timer ticks before it is due” Errors |
|
Infrequent Ooops: timer ticks before it is due messages appear on the console. You can safely ignore this message, because it is harmless.
Infrequent “e1000: eth1: e1000_clean_tx_irq: Detected Tx Unit Hang” Errors |
|
Infrequent e1000: eth1: e1000_clean_tx_irq: Detected Tx Unit Hang messages appear on the console. You can safely ignore this message, because it is harmless.
Inconsistent “Bogomips” Values between Virtual CPU0 and Other Virtual CPUs |
|
“Bogomips” values can be inconsistent between virtual CPU0 and other virtual CPUs. This condition is harmless. To prevent this problem, add the lpj=4000000 boot option in /boot/efi/efi/redhat/elilo.conf. For example:
# cat elilo.conf
prompt
timeout=20
default=linux
relocatable
image=vmlinuz-2.6.9-42.EL.img
label=linux
initrd=initrd-2.6.9-42.EL.img
read-only
root=/dev/VolGroup00/LogVo100
append="console=tty0 console=ttyS0 rhgb quiet lpj=4000000 |
Incorrect Display of Special Characters when Displayed Using HP-UX Terminal |
|
The Linux Red Hat installation program does not display correctly when run within hpvmconsole on an HP-UX terminal. It displays accented A characters instead of boxes.
Occasional Floating-Point Assist Fault Messages. |
|
Occasional floating-point assist fault messages appear when running Mozilla. This problem also occurs on native Integrity servers running Linux. For more information, see the “Developer & Solution Partner Program (DSPP)” web page on http://www.hp.com, and search for “floating-point assist fault”.
