invalid config.guest.cpu_kind, only \"shared\" CPU currently supported

Last week I successfully managed to spin up machines with the following command:
fly machine run image -a app -r fra -s dedicated-cpu-2x

Now I receive the following error message
Error could not launch machine: failed to launch VM: invalid config.guest.cpu_kind, only "shared" CPU currently supported

At when do you plan to support this again?

It’ll be a while! We’re working out a higher CPU option for machines right now. We decided to release machines with just shared CPUs, but allow up to 8x of them.

-s shared-cpu-2x should give you similar CPU performance most of the time (our CPUs are generally under utilized).

If you’re not pegging CPU from your Machine, that shared one should be pretty good.

got it. Thanks for the help kurt, I appreciate it
