Yes (lowest vCPU seems to be 2 everywhere), and that protects against this attack. However, this thread was talking about airgapping hosts, which is needed for the general threat of VM escapes.

At least Fargate and Lightsail can select < 2 vCPU. (and maybe micro EC2 instance types?)

Well, that does sound like those were vulnerable then, if they happened to run on Zen 2. (Obviously microcode patched by now.)

As usual, cost is the biggest hindrance to security.
