Supported Guests and Allocating Resources | Citrix Systems 6.2.0

Chapter 3. Supported Guests and Allocating Resources

This chapter describes how to allocate resources to your VMs, and the supported guest operating systems. It lists virtual memory and virtual disk size minimums, and describes the differences in virtual device support for the members of the XenServer product family.

3.1. Supported Guests, Virtual Memory, and Disk Size Limits

When installing VMs, follow the memory and disk space guidelines of the operating system and any relevant applications, when allocating resources such as memory and disk space.

Note:

Individual versions of the operating systems may also impose their own maximum limits on the amount of memory supported (for example, for licensing reasons).

Warning:

When configuring guest memory, do not to exceed the maximum amount of physical memory addressable by your operating system. Setting a memory maximum that is greater than the operating system supported limit may lead to stability problems within your guest.
