Configuring and Running Virtual Machines

194

www.vmware.com

• The user must have read access to the configuration file to use the local console

on the console operating system or to connect to the virtual machine with the

VMware Perl API.

• The user must have read and execute access to the configuration file to

connect to and control (start, stop, reset or suspend) a virtual machine in a

remote console, with the VMware Perl API or with the management interface.

• The user must have read and write access to the configuration file to change

the configuration using the Configure VM page in the VMware Management

Interface.

Note: If you have users with list access, but not read access, they may encounter

errors in the VMware Management Interface.

If a vmware process is not running for the configuration file you are trying to use,

vmware-authd examines /etc/vmware/vm-list, the file where you register

your virtual machines. If the configuration file is listed in vm-list, vmware-authd

(not necessarily the user who is currently authenticated) starts VMware ESX Server as

owner of this configuration file.

Registered virtual machines (those listed in /etc/vmware/vm-list) also appear

in the VMware Management Interface. The virtual machines you see on the Overview

page must be listed in vm-list, and you must have read access to their

configuration files.

The vmware-authd process exits as soon as a connection to a vmware process is

established. Each vmware process shuts down automatically after the last user

disconnects.

Default Permissions

When you create a virtual machine with VMware ESX Server, its configuration file is

registered with the following default permissions, based on the user accessing it:

• Read, execute and write — for the user who created the configuration file (the

owner)

• Read and execute — for the owner’s group

• Read — for users other than the owner or a member of the owner’s group

TCP/IP Ports for Management Access

The TCP/IP ports available for management access to your ESX Server machine vary,

depending on the security settings you choose for the server. If you need to manage

ESX Server machines from outside a firewall, you may need to reconfigure the firewall
