Virtualization Host Requirements
This section provides information on the minimum hardware requirements to support RHEV-H and Red Hat Enterprise
Linux Hosts.
Processor
All processors must support Intel 64 or AMD 64 processor extensions, and the AMD-V or Intel VT hardware virtualization
extensions must be enabled. Support for the No eXecute flag (NX) is also required.
Memory
It is recommended that virtualization hosts have a minimum of 2 GB RAM. The amount of RAM required varies depending
on:
• Guest operating system requirements
• Guest application requirements
• Memory activity and usage of guests
KVM is able to overcommit physical RAM for virtualized guests. Overcommit allows the RHEV environment to present
more memory to guests than is actually physically present. The default overcommit ratio is 0.5.
Storage
Virtualization hosts require local storage to store configuration, logs, kernel dumps, and to swap space. The storage
requirements for Red Hat Enterprise Linux hosts vary based on the amount of disk space used by their existing
configuration, but should be greater than the RHEV-H.
It is recommended that each virtualization host has minimum 10 GB of internal storage comprising of:
• Root partition — 512 MB
• Configuration partition — 8 MB
• Logging partition — 2048 MB
• Swap partition — 8 MB
• Data partition — 256 MB
NOTE: The recommended size of the swap partition depends on the system the hypervisor is being installed on
and the anticipated level of overcommit for the environment.
NOTE: You may not be able to upgrade the hypervisor from the RHEV-M if you use a smaller data partition. By
default, disk space remaining after allocation of swap space will be allocated to the data partition.
