Hmm, that is outside the scope of conversion. It depends on the machines configurations.
Take into account NIC's MAC addresses will change.You can set static IP addresses for the destination machines in Converter wizard (part of customization). In theory you could preserve the IP addresses (if they are static and can be kept the same in the virtual network) though this is quite unlikely.
Most probably DNS must be configured additionally.
I am not sure whether the VMs must be joined to the domain explicitly but expect they should. This can also be done as part of customization.
