Re: JEOS host
@AC thanks, I will investigate JEOS. It definitely seems like promising direction. Name "Oracle" is little off-putting, though (but hey, it is still FOSS so I'm not going to complain).
And yes, I am definitely not going to mess with Linux hypervisor, any actual work or experimentation is going to be in a "sibling" virtual machine. This hypervisor is actually the only Linux OS I want to have an option for support.
