Maybe we'd better use existing qemu accelerator framework and introduce

My worry would be breaking existing code which assumes kvm | tcg. We
will want to enable mttcg by default for combos that work without having
to tweak tooling that already uses the -machine options.
Comments from the peanut gallery:
* We definitely want to just default to MTTCG where it works:
users shouldn't have to add new command line switches to get the
better performance etc, because in practice that won't happen
* Anything that adds a new command line option at all has to
be supported practically forever, so options that are only
useful for a transitional period are worth thinking twice about
Yes, but users may like to have an option to disable MTTCG for some
reason. I'm also concerned about icount mode: not sure how to account
virtual time when all vCPUs run in parallel.
Hi,
I'm thinking the same, we don't have a solution for icount yet.
The reverse execution support is probably badly broken as well.

Kind regards,
