The paravirtualized HOSS hypervisor is developed based on the MIT-JOS exokernel Operating System. The HOSS hypervisor is developed by leveraging the Intel VT-x hardware extensions for virtualization.
This implementation is adapted for the Intel x86_64 architecture. Testing can be performed on a Bochs x86 emulator with a single x86_64 processor having VT-x extensions enabled and 256 MB of main memory.
1 - Check for VMX support
2 - Check for Extended Page Table support
3 - Modifcations for scheduling a guest environment
4 - Implementation of Extended Page Table for handling Guest to Host physical address mappings
5 - Assembly code to launch the Guest environment, by mapping JOS guest kernel and bootloader into the Virtual Machine’s memory segment
To run the JOS kernel: make bochs
To launch the Guest VM after the JOS kernel boots up: vmm
Implementation is based on the CSE591-Virtualization course at Stony Brook University.
