When importing a VM or vApp from vCenter into vCloud you may see an error like this:
A specified parameter was not correct.
spec.deviceChange.device.port.switchUuid
This can happen when comign from a Cisco Nexus 1000v Portgroup, to solve this either remove the network adapter for importing into the cloud, or move the network card to a portgroup that is not a Nexus 1000v Portgroup.
If you are using a dVS and see this error move the NIC to a standard vSwitch or delete the NIC and re-add it once it is in the cloud.
