You can modify virtual machine network settings, reset a MAC address, add a network interface, and delete a network interface.
The number of NICs supported in an individual VM is determined by the virtual hardware version. vCloud Director supports modifying virtual machine NICs while the virtual machine is running.
Support for SR-IOV Devices
VMs that have been configured in vSphere with one or more NICs that support Single Root I/O Virtualization (SR-IOV) can be imported into vCloud Director and included in vApps.
To enable use of SR-IOV devices by vCloud Director VMs, the vSphere port group to which the physical SR-IOV devices are connected as uplinks must be mapped to a vCloud Director external network. This is the only kind of vCloud Director network that an SR-IOV NIC can connect to. Unless such an SR-IOV-capable external network is available in your VDC, you cannot connect an SR-IOV device.
- They are not affected by vMotion or Storage DRS.
- They cannot be suspended.
- You cannot take a vCloud Director snapshot of a VM that is configured for SR-IOV.
- Hot reconfiguration of CPU, memory, and virtual hardware is not supported.
