A paused guest still can have some action in I/O threads or UI, but 15% seems a lot.

None of the automatic logs helps for this.
You should gather some metrics which thread is using the CPU and where.
  pidstat -p $(pidof qemu-system-x86_64) -T ALL -rtuw 5 5

Report that back here on the bug to discuss what it might be.
In a check with a paused linux guest that stays <1% for me.

If you have more guests up identify the PID of the one in question and use it instead of `$(pidof qemu-system-x86_64)`
