No one likes downtime but I suspect this is one of those serious vulnerabilities that you really really must be protected against. That being said, before planning downtime, check your HW vendor for firmware or Intel for microcode for the host first. Without it, there's not a lot of protection anyway. Note that there are 4 steps you need to take to be fully protected: CPU, hypervisor, guests and guest CPU type - plan ahead! Y.
Is there a HOW-To written up somewhere on this? ;) I built the hardware from scratch myself, so I can't go off to Dell or someone for this. So which do I need, motherboard firmware or Intel microcode? I suppose I need to go to the motherboard manufacturer (Supermicro) to look for updated firmware? Do I also need to look at Intel? Is this either-or or a "both" situation? Of course I have no idea how to reflash new firmware onto this motherboard -- I don't have DOS. As you can see, planning I can do. Execution is more challenging ;) Thanks!
