[PATCH 1/2] qemu_process: Issue an info message when subtracting isolcpus
In one of my previous commits I've made us substract isolcpus
from all online CPUs when setting affinity on QEMU threads. See
commit below for more info on that. Nevertheless, this is
something that surely deserves an entry in log. I've chosen INFO
priority for now. We can promote that to a regular WARN if users
complain.
