<title>System Requirements for KVM Hypervisor Hosts</title>
|
|
<para>KVM is included with a variety of Linux-based operating systems. Although you are not required to run these distributions, the following are recommended:</para>
|
|
<itemizedlist>
|
|
<listitem><para>CentOS / RHEL: 6.3</para></listitem>
|
|
<listitem><para>Ubuntu: 12.04(.1)</para></listitem>
|
|
</itemizedlist>
|
|
<para>The main requirement for KVM hypervisors is the libvirt and Qemu version. No matter what
|
|
Linux distribution you are using, make sure the following requirements are met:</para>
|
|
<itemizedlist>
|
|
<listitem><para>libvirt: 0.9.4 or higher</para></listitem>
|
|
<listitem><para>Qemu/KVM: 1.0 or higher</para></listitem>
|
|
</itemizedlist>
|
|
<para>In addition, the following hardware requirements apply:</para>
|
|
<itemizedlist>
|
|
<listitem><para>Hosts must be certified as compatible with the selected operating system. For example, see the RHEL Hardware Compatibility Guide at https://hardware.redhat.com/.</para></listitem>
|
|
<listitem><para>Within a single cluster, the hosts must be of the same kernel version. For example, if one host is RHEL6 64 bit, they must all be RHEL6 64 bit.</para></listitem>
|
|
<listitem><para>All hosts within a cluster must be homogenous. The CPUs must be of the same type, count, and feature flags.</para></listitem>
|
|
<listitem><para>Must support HVM (Intel-VT or AMD-V enabled)</para></listitem>
|
|
<listitem><para>64-bit x86 CPU (more cores results in better performance)</para></listitem>
|
|
<listitem><para>Hardware virtualization support required</para></listitem>
|
|
<listitem><para>4 GB of memory</para></listitem>
|
|
<listitem><para>36 GB of local disk</para></listitem>
|
|
<listitem><para>At least 1 NIC</para></listitem>
|
|
<listitem><para>Statically allocated IP Address</para></listitem>
|
|
<listitem><para>Latest hotfixes applied to hypervisor software</para></listitem>
|
|
<listitem><para>When you deploy &PRODUCT;, the hypervisor host must not have any VMs already running</para></listitem>
