HP Integrity Virtual Machines Manager Version 4.0 Getting Started Guide

Setting Security Credentials
To display the full range of data about each virtual machine in VM Manager, you must have
WBEM-recognized credentials for each virtual machine. A user name and password are required
to collect resource utilization and other data, such as the status of the installed operating system.
This data is available only from a WBEM provider on the VM Host or virtual machine. The
WBEM providers are the tools used to gather data about the virtual machine and the VM Host.
The user interface uses this information to show various kinds of system status.
You can set credentials by specifying a default user name and password combination for any or
all virtual machines. You can also override the default user name or password on a case-by-case
basis.
NOTE:
• For a given virtual machine, if no user name or password is specified, the default is used.
• If a password is specified but a user name is not, the default user name is used with the
password override. This allows a system administrator to use the same user name but
different passwords for each virtual machine.
When running VM Manager through VSE Management Software under HP SIM, HP SIM is
responsible for managing the credentials needed for using WBEM providers on the VM Host
and on virtual machines. When running VM Manager under HP SMH, HP SMH manages
credentials and access for the VM Host on which HP SMH is running; credentials for each virtual
machine are managed by VM Manager.
The method for setting WBEM credentials depends on whether you are using HP SIM or HP
SMH.
Setting WBEM Credentials in HP SIM
Any virtual machines that are not managed nodes do not have any credentials available, and
VM Manager cannot contact them. These machines are displayed, but some of the information
that can be gathered from the managed nodes is not displayed for non-managed nodes.
You can set credentials in HP SIM for a global configuration across multiple systems by selecting
Options→Protocol Settings→Global Protocol Settings...; for a single managed node, set
credentials by selecting Options→Protocol Settings→System Protocol Settings.... VM
Manager requires that the proper WBEM credentials (a valid user name and password) be set
in those option pages. Without WBEM, the Virtualization Manager and HP Capacity Advisor
functionality will not be available; only HP Global Workload Manager (gWLM) is functional.
With HP SIM, you can set the credentials when you first launch HP SIM after installation by
using the HP SIM First Time Wizard. For information about setting credentials, see the HP VSE
Management Software Version 4.1 Installation and Update Guide for HP-UX.
Setting WBEM Credentials in HP SMH
You must set WBEM credentials for virtual machines in HP SMH. This allows VM Manager to
collect utilization data and operating system information on the virtual machine. Stored credentials
are specific to the user logged in to HP SMH. Two users who are logged in with different user
names do not share credentials.
When you log into SMH without having already set the WBEM credentials and saving them in
the file system, the Set WBEM Credentials for Vir tual Machines page is displayed. When you
create a new virtual machine, you must add credentials for that virtual machine by selecting
Modify→WBEM Credentials... from the VM Manager menu bar, which displays the same page.
Figure 2-1 shows an example of the Set WBEM Credentials for Virtual Machines page.
