Hi,
i have a dumb question: what is the "--enable-io-thread"? Is this a
kvm-switch?
My kvm 0.12.4 don't accept this switch. I'm know only "threads=n" as
smp-parameter and "aio=threads" as drive-parameter.
Because i look for a solution for a better io-performance of
windows-guest with more than one cpu...
best regards
Udo
