4.3.4 ACPI Warnings, Errors, and Exceptions Displayed when SUSE Guest Booted
When an installed SUSE guest is booted, messages similar to the following are displayed on the
guest's console:

These warnings, errors, and exceptions occur because some optional elements are not provided
by the Integrity VM ACPI table. These messages are printed because the SUSE startup/initialization
code is trying to reference these optional elements, particularly for configured guest CPUs.
The messages do not impede the SUSE boot process; the boot/startup process completes. The
only known side-effect of these messages is that there is an extra CPU created in the /proc/
acpi/processor file system, which might lead to confusion as to the actual number of CPUs
configured in the guest.
4.3.5 HP SIM CMS Cannot Connect to SLES10 over SSH
SSH password authentication is turned off by default in SLES10. In this default setting, HP SIM
CMS cannot connect to the SUSE guest.
To enable password authentication for SSH, do the following:
1. Login to SUSE.
2. Edit the /etc/ssh/sshd_config file.
3. Set passwordauthentication value to yes.
4. Restart sshd.
For more information, see Secure Shell (SSH) in HP SIM 5.x, Troubleshooting section (page 31).
4.3.6 Preparing Linux Guests for VM Manager
If Linux guests are to be managed by VM Manager:
1. Install the tog-pegasus package.
2. 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.
a. Look for the following line in this file:
-: ALL EXCEPT pegasus:wbemNetwork
b. Change this line to either of the following options:
