A virtual machine with a directly assigned network device and supported on a host may be migrated to other host without loss of network connectivity. Such migration is enabled by bonding a physical network interface driver (NIC) and a virtual NIC driver of the host. A virtual machine monitor of the host may determine whether the virtual machine is to be migrated to the other host. The virtual machine monitor may allow hot-plug removal of the network device. However, the virtual machine may still maintain network connectivity through the virtual NIC. The virtual machine may be migrated to the other host. After migration, the virtual machine may continue to maintain the network connectivity either through the virtual NIC driver or bond with a physical NIC driver of the network device coupled to the other host.
