Hello all,

I will do research experiment using hypervisor. But I have not decided the platform; both XEN and KVM work for me(my work is about MMU, specifically shadow page tables). Though I prefer XEN, it seems XEN development and debugging are not easy. For example, every time you add some code in hypervisor, you have to restart computer.

I appreciate your suggestion.


Thanks
Liu, John

I am curious to know under what circumstances you think it is, or should be possible to make hypervisor code changes without rebooting?
