1. A method for onboarding a virtual machine in a bridge host extension mode comprising:
creating a virtual machine on a host computing device, wherein the host computing device is associated with a first MAC address and a first IP address;
assigning the virtual machine a second MAC address by the host computing device, wherein the second MAC address is different than the first MAC address and is unique to the virtual machine;
receiving a first DHCP packet from the virtual machine by the host computing device, wherein the first DHCP packet comprises a first field that includes the second MAC address;
replacing the second MAC address in the first field with the first MAC address by the host computing device;
adding the second MAC address to a second field of the first DHCP packet by the host computing device; and
providing the first DHCP packet to a DHCP server through a network by the host computing device, wherein the DHCP server stores the first and second MAC addresses and uses the stored first and second MAC addresses to profile the virtual machine.
