CPU halted during fuzzing OHCI
Description of problem:
Is there a limit on the number of CPU cores that QEMU can use? I am running multiple sets of parallel fuzzing tests on a host machine. To prevent CPU contention, I have divided the running environments by using docker. The docker startup command is as follows:
`docker run --cpuset-cpus=8-15 --privileged --name qemu-container-ohci -it qemu-container bash`
I found that the CPU is in a halted state and encountered the following error:
```

```
Can someone help analyze the reason?
