cPanel Supported Virtual Environments

cPanel products support the following virtual environments:

Virtual environment	Additional restrictions
KVM	None. Note: If you use a Linux bridge on a KVM server, you may experience problems with multicast routing. These problems affect the server's ability to resolve nodes on the network. For example, IPv6 Stateless Address Autoconfiguration (SLAAC) addresses may drop off intermittently, or the server may experience problems when it attempts to find the router. To resolve this issue, set the `multicast_router` system knob value to `2`. For more information, read the CentOS-virt mailing list thread.
Linux Containers	cPanel & WHM requires additional configuration to run inside a Linux Container. For more information, read official Linux Containers and cPanel documentation.
Linux-VServer	None.
Microsoft Server® 2008 Hyper-V, Microsoft Server 2012 Hyper-V	cPanel only supports the drivers and configurations that Microsoft provides.
