AFAIK, no.
Why don't you simply start QEMU in the cgroup ? Unless I miss something, all
children threads, including the 9p ones, will be in the cgroup and honor the
throttle setttings.

This being said, QEMU is a regular userspace program that is completely cgroup
agnostic. It won't behave differently than 'dd if=/dev/sdb of=/dev/null'.
This really doesn't look like a QEMU related issue to me.

No it is not. There's a migration blocker as long as the 9p file system is
mounted in the guest.
