Nachtrag:
pCI: we have confirmation that KVM is immune to guests reading HV or other guest memory via variant 3 (aka meltdown). KVM is NOT "impacted" by Meltdown. So, right now, a guest VM cannot read another VM's memory, neither the HOST 's memory.

Und noch ein Nachtrag:
https://www.qemu.org/2018/01/04/spectre/
"Right now, there are no public patches to KVM that expose the new CPUID bits and MSRs to the virtual machines, therefore there is no urgent need to update QEMU; remember that updating the host kernel is enough to protect the host from malicious guests."
