1. A method comprising: receiving, by a processing device executing a pre-boot management engine via a network from a remote physical machine, a set of pseudo hardware-based identifiers comprising a set of pseudo media access control (MAC) addresses and representing a set of virtual machines hosted by the remote physical machine and managed on a time-sliced basis, wherein resources of the remote physical machine are available to each virtual machine in the set of virtual machines at a regular interval, and wherein the remote physical machine is without pre-boot management logic; generating, by the processing device executing the pre-boot management engine, a set of pre-boot commands in view of the set of pseudo hardware-based identifiers, the pre-boot commands to control operation of the set of virtual machines prior to loading an operating system on the set of virtual machines; and transmitting the set of pre-boot commands, via the network, to the remote physical machine hosting the set of virtual machines for execution by the set of virtual machines.
