If i need to some kvm module, that runs in virtualized environment and
reports some statistics to qemu (disk free space, memory usage, cpu
utilization) what i need to write?
I need kernel module, because userspace utilities under heavy load can't send
such information via
network (for example snmp under load does not respond).
Does kvm have skeleton module, what i can use and append code needed
for me?
I recommend using virtio-serial in userspace. If your load is very
high, you can use mlockall() and sched_setscheduler() to keep the
process in memory and on a cpu.
If you absolutely need a kernel module, you can base it off virtio-serial.
