<title>Choosing a Hypervisor: Supported Features</title>
|
|
<para>&PRODUCT; supports many popular hypervisors. Your cloud can consist entirely of hosts running a single hypervisor, or you can use multiple hypervisors. Each cluster of hosts must run the same hypervisor.</para>
|
|
<para>You might already have an installed base of nodes running a particular hypervisor, in which case, your choice of hypervisor has already been made. If you are starting from scratch, you need to decide what hypervisor software best suits your needs. A discussion of the relative advantages of each hypervisor is outside the scope of our documentation. However, it will help you to know which features of each hypervisor are supported by &PRODUCT;. The following table provides this information.</para>
