User ID Pattern
Pattern for generating z/VM user IDs. To z/VM, a z/VM virtual server is a guest virtual machine. When you create a z/VM virtual server based on this template, you are creating a guest virtual machine with a user ID according to this pattern.
The user ID Pattern:
  • Can be one to 8 characters
  • Consists of alphabetic (A-Z), numeric (0-9) and the following special characters: @ # $ _ (underscore) - (hyphen)

    Although allowed, avoid using: @ #

  • Can end with a trailing * (asterisk) that represents the variable part of the pattern.

The generated user IDs all commence with the specified base name of alphanumeric and permitted special characters. A trailing * (asterisk) is replaced by digits that are counted up from zero. When a user ID is generated, the first free ID is assigned that matches the pattern.

The more digits are covered by the wildcard character, the greater is the number of unique user IDs that can be provided. If the specified user ID pattern, including wildcard, is less than eight characters, the generated names are padded with zeros.

Examples:
LINUXVS*
would provide for the 10 user IDs from LINUXVS0 through LINUXVS9
LINUX*
would provide for the 1000 user IDs from LINUX000 through LINUX999

Avoid using patterns that resolve to z/VM commands and reserved user IDs. Refer to z/VM® CP Command and Utility Reference, SC24-6081, for more information.

Password
1 to 8 character initial password for the user ID of the User ID field. Adhere to your installations password regulations when specifying initial passwords. If you do not provide an initial password, an 8-character password is generated for you. After a z/VM virtual server has been created, you can find the password on the Overview page of the z/VM Virtual Server pane.

This password is applicable only for installations that do not use Resource Access Control Facility (RACF) for security. You need this password only if you want to use a 3270 terminal to log on to the z/VM guest virtual machine with the user ID of the User ID field.

User Class
Defines the privileges that the z/VM virtual server has on the z/VM system. Consists of one or more characters where each character can occur once only. The characters must be uppercase alphabetic (A-Z) characters or numeric characters in the range 1-6.

Classes A-H are predefined but can be modified by a system administrator for a particular installation; the remaining classes are always installation-specific. Refer to CP Planning and Administration, SC24-6083, chapter 16 "Redefining Command Privilege Classes" for details.

Prototype
Advanced option: Specifies a set of defaults to be used for your z/VM virtual server. The values that you specify in this wizard override the values in the referenced prototype.

If you are using z/VM Directory Maintenance Facility (DirMaint) as your z/VM directory manager, refer to the DIRMaint Add command in z/VM Directory Maintenance Facility Commands Reference, SC24-6133, for more details.

Processor Count
Number of virtual processors assigned to the system. Assigning more than one processor allows multitasking that requires multiple processors regardless of the availability of multiple real processors. The value must be an integer in the range 1 - 64.
Initial Memory size
Amount of memory assigned when the z/VM virtual server is started.

You can assign any amount of initial memory from 64 KB to the architectural limit of 16 EB. The default is 512 MB.

The value must be a number directly followed by one of the letters K (for kilo), M (for mega), G (for giga), or T (for tera). Be sure to assign memory that is within the hardware capabilities in terms of available real and virtual storage.

Example: The specification "256K" would allocate 256 KB = 262 144 Byte of initial virtual memory.

Max. Memory size
Maximum amount of memory that the z/VM virtual server can claim from z/VM.

The maximum memory size must be equal to or greater than the initial memory size The value must be a number directly followed by one of the letters K (for kilo), M (for mega), G (for giga), or T (for tera). Be sure to assign memory that is within the hardware capabilities in terms of available real and virtual storage.

Example: The specification "1G" would limit the amount of memory that the z/VM virtual server can claim to 1 GB = 1 073 741 824 Byte.
