QEMU supports migration of a virtual machine across machine over the network. It also has the capability to save the state of a virtual machine and resume from that state.
It is described in detail in https://www.linux-kvm.org/page/Migration
This capability can be leveraged to create an instant resume virtual machine image if the virtual machine is crafted with care.
