6 Guest Administration This chapter contains information about managing Integrity VM guests. 6.1 Administrator Account Names This version of Integrity VM lifts the restriction that the virtual console administrator account names must be the same as the guest name. As a result, the virtual console administrator name can be any valid HP-UX login name. To continue accessing the virtual console, existing guest console accounts must be added to the authorization list for the associated guest with the usermod command. This allows multiple accounts to map to the guest, and requires the account names to be valid HP-UX login strings. Authorization of access to the virtual console is determined by the guest configuration file (set using the -u and -g options to the hpvmcreate, hpvmmodify, and hpvmclone commands). This controlled access allows you to temporarily block access by using the hpvmmodify command to change the virtual console administrator account name. 6.2 Guest User Accounts The configuration for captive hpvmconsole guest user accounts has changed in this release to support additional access controls and configurations. This change requires that the guest user accounts have the correct home directory. It is also necessary to list the console access account in the guest configuration file. For example, using a guest named compass1 (and therefore a user account named compass1), the home directory for user compass1 must be /var/opt/hpvm/guests/compass1. To ensure that the user continues to have administrative console access, use the following command: # hpvmmodify -P compass1 -u compass1:admin 6.3 Creating Virtual Machine Administrator and Operator Accounts In prior versions of Integrity VM, only admin console access is available, and only one such account per guest is allowed. The administrator account name must match the guest name. The new version of Integrity VM provides proper access controls and individual accountability for these accounts. A captive virtual console account is a special-purpose user account created on the VM Host for each guest administrator. These types of user accounts use /opt/hpvm/bin/hpvmconsole for a shell, and the desired guest's per-guest directory for a home directory. For virtual console access, the account also requires a password, and access to its associated guest. You create this account with the hpvmcreate, hpvmclone, or hpvmmodify command. You can establish group membership of the account using the -g option to those commands, or user membership, using the -u option to those commands. NOTE: Do not use the hpvmsys group for user accounts. This group is used for security isolation between components of Integrity VM. The HP-UX useradd command may not work as expected. To create user accounts for virtual console access, use the useradd command before you create the virtual machine. Alternatively, specify the user account directory completely in the /etc/passwd file, ensuring the entry is unique. In the following example, the useradd command is used to create three user accounts on the VM Host system (testme1, testme2, and testme3): # useradd -r no -g users -s /opt/hpvm/bin/hpvmconsole \ -c "Console access to guest 'testme'" \ 6.1 Administrator Account Names 37
