In addition to OS patches, I assume we ought to be looking for BIOS updates as well, which, with many of our ancient desktops, there will probably be none.
I don't expect any for my 3 year old laptops, let alone my 5-7 year old desktops.
The question then is whether or not the OS patching will be sufficient.
While these are some pretty nasty vulnerabilities, I don't currently consider them that horrible. As I understand it (and I leave TONS of room to learn new things about these) you can only be affected if you run untrusted code on your system. Assuming that webpages can't take advantage, this amounts to the same level of issue as a typical virus.
Assuming hardware vendors don't produce updates for hardware more than say 3 years old - how many here are going to be replacing their machines/devices (don't forget your android phones are affected too - last I heard)?
In a desktop or laptop case, the risk is tiny compared to the big fear of shared computing environments.

Depends if it is Intel based or from a more security-minded vendor.
All Dell and all Intel.

The risk is not based on OS, so can't be determined by something like "Android phone." Some Androids are affected, some are not.

Then an OS patch cannot fix it.

While I understand the problem itself is with the chip, aren't the OS patches being released supposed to alter how memory is handled, which doesn't fix, but rather mitigates the problem (and potentially lowers performance)?

I want to know how this effects hosts... does just the host need patched, or every VM?

Right, the flaw is a literal bug and affects Intel. The broader (but less dangerous) issue is that certain types of processor tasks, mixed together, without being addressed by the OS, create a risk in memory.

So the true 100% fix is really going to be hardware replacement, unless it can be address by some kind of lower-level flash update of the hardware.

But no question, we should all be questioning the use of Intel hardware in the future. We've always excused their FakeRAID stuff as a one-off misunderstanding of business customers; but this has shown that the same disregard for their customers and lack of proper thinking is much more broad and not limited to that one division.

Hardware replacement fixes Meltdown, but not Spectre, as the latter is an issue on almost all systems.

And I imagine the way to get it is from your computer's manufacturer, which for your ancient workstations, there probably won't be an update released.
Right now, I'm trying to see if SuperMicro has any kind of update I can apply to our production servers.

But isn't majority of vendors who sells servers only sell Intel based servers?

No, in fact one of the biggest sells no Intel at all (IBM) and one of the biggest sells it only as a secondary (Oracle.) In fact, AFAIK, the only large vendor without something other than Intel in their lineup, was Dell and Dell changed their tune like eight months ago when AMD brought out their awesome new line of EPYC processors.
There is always options to go without Intel. Intel was just so heavily focused on being tied to Windows licensing that people just kept using it without looking for anything else.
