[Qemu-discuss] Spectre/Meltdown Host And Guest Mitigations

I have a couple of questions regarding protecting a compute/hypervisor
host and the guests residing on this host.

So as a start...

If I enable mitigations at the host, but disable mitigations within a
single guest(all other guests have mitigations enabled),
I am guessing I only expose the single guest to potential 'attack',
and other guests(and the host) are still protected..

Please advise
