Subject: Setting disk parameters in a VM
Date: Fri, 13 Mar 2009 12:58:26 -0400 [thread overview]
Message-ID: <49BA90B2.80804@tmr.com> (raw)
Based on a discussion in another list on ioschedulers, I added a few
lines to my rc.local to set the scheduler to "noop" for disks with model
QEMU*, to the scheduling in the VM will not be computing with the
scheduling in the host.
I wonder if the same thinking applies to the "rotational" feature added
to /sys/block in 2.6.29, intended for SSD but probably appropriate for
virtual and nbd devices as well.
