An Overview of Red Hat Enterprise Virtualization - Getting Started with Red Hat Enterprise Virtualization - page 10

The Red Hat Enterprise Virtualization Hypervisor host
One or two physical hosts act as virtualization hosts or RHEV-H. A minimum of two hy-
pervisor hosts is required to demonstrate and test the live migration of virtual machines
across hypervisor hosts.
Intel or AMD 64-bit supported hardware with virtualization extensions support of Intel
VT or AMD-V enabled with following minimal compute requirements:
• 2 GB RAM
• 2 GB local disk space
• One network interface with a bandwidth of 1 GBps
The recommended hardware for virtualization hosts always varies as per your require-
ment. Consider the following basic factors before sizing your hardware:
• The number of guest operating systems, their application memory, and CPU re-
quirements. For network-intensive application workloads, add multiple network
interfaces and segregate the network traffic using RHEV's logical networks.
• For less critical and non-disk I/O-intensive applications, use local storage, and in
this case, extend the internal storage size of virtualization hosts in order to store
the virtual machine images as per your requirement. However, keep in mind that
the use of local storage will prevent other features such as live migration of virtu-
al machines to other hosts.
• For high transnational database workloads, use the NAS/SAN storage with a ded-
icated network interface in the case of NAS and FC for SAN.
• Virtualization hosts must run Version 6.3 or higher of either the RHEV hypervisor
host or Red Hat Enterprise Linux Server as a host.
The Red Hat Enterprise Virtualization Manager client
In order to access the manager, you need the following supported clients and browsers:
• Mozilla Firefox 17 or higher is required to access both portals on Red Hat Enter-
prise Linux.
• Internet Explorer 8 or higher is required to access the user portal on Microsoft
Windows. Use the desktop version and not the touchscreen version of Internet
Explorer 10.
• Internet Explorer 9 or higher is required to access the administration portal on Mi-
crosoft Windows. Use the desktop version and not the touchscreen version of In-
ternet Explorer 10. It's possible to access the manager portal from other browsers,
