Ok that seems to work: it removes the vhost part in the virsh launch
hence cutting down 12secs of boot time.
If nobody comes out with an explanation of why, I will open another
thread on the kvm list for this. I would probably need to test disk
performance on vhost=on to see if it degrades or it's for another
reason that boot time is increased.
Is it using CPU during this time, or is the qemu-kvm process idle?
It wouldn't be the first time that a network option ROM sat around
waiting for an imaginary console user to press a key.
Rich.
Of the two qemu-kvm processes (threads?) which I see consuming CPU for
that VM, one is at about 20%, the other at about 10%. I think it's doing
something but maybe not much, or maybe it's really I/O bound and the I/O
is slow (as I originarily thought). I will perform some disk benchmarks
and follow up, but I can't do that right now...
Thank you
