Virtual Machine Requirements
Hypervisor features may differ depending on the hypervisor, and not all features in a given hypervisor
version may be supported. The hypervisor versions listed are those officially tested and supported by the
Cisco CSR 1000V. See the following sections for more information:
•VMware ESXi Support Information, page 4-1
•Citrix XenServer Support Information, page5-1
•Kernel Virtual Machine Support Information, page6-1
•Microsoft Hyper-V Support Information, page7-1
Hypervisor vNIC Requirements
Depending on the Cisco CSR 1000V release version, each of the hypervisors supports different virtual
network interface card (vNIC) types. The Cisco CSR 1000V also supports a different maximum number
of vNICs depending on the hypervisor. Some versions and hypervisors also support the ability to add
and remove vNICs without powering down the VM. This feature is known as vNIC Hot Add/Remove.
The following table lists the supported vNICs and the minimum and maximum number of vNICs
supported for each VM instance.
