Process core isolation for execution of multiple operating systems on a multicore computer system includes booting first and second operating systems (OSs) on a computer system that includes a plurality of processor cores across physical central processing unit(s) (CPUs). Booting the first OS boots the first OS on a first subset of the processor cores. Booting the second OS, different from the first OS, boots the second OS on a second subset of the processor cores. The first and second subsets are mutually exclusive, where a first processor core of a physical CPU of the physical CPUs is included in the first subset and a second processor core of the physical CPU is included in the second subset, and where the first and second OSs execute concurrently on the computer system, and each of the first and second OS executes on only its respective subset of processor core(s).

Dedicating hardware devices to virtual machines includes dedicating, by a hypervisor executing on a computer system, a set of hardware devices of the computer system to a first virtual machine of the hypervisor, the first virtual machine executing a guest operating system, and the set of hardware devices for use by the guest operating system in execution of the guest operating system, and dedicating network device hardware of the computer system to a second virtual machine of the hypervisor, the second virtual machine being a different virtual machine than the first virtual machine, wherein network communication between the guest operating system and a network to which the computer system is connected via the network device hardware occurs via the second virtual machine.
