Perf team used to have a tool called tuna that made it possible to apply profiles to hosts, and one of the profiles was for a 'kvm host' @mwagner, can you assist with info here?

I thought Packstack was going to use otopi/ovirt-host-deploy. It's available there: http://gerrit.ovirt.org/gitweb?p=ovirt-host-deploy.git;a=blob;f=src/plugins/ovirt-host-deploy/tune/iosched.py;hb=HEAD Hi, tuned is a user space package that controls the profiles. There are profiles for virtual-host and virtual-guest amongst others. It should be possible to install and configure the use of the virtual-host profile. Note that tuna is a different tool. I have to translate this into a equivalent puppet manifest but would something like this be appropriate ? if ! tuned-adm active | grep virtual-host 2> /dev/null ; then tuned-adm profile virtual-host fi This probably changes more then just the IO scheduler but its all good stuff right? Also does this changed persist on reboot? thanks, Derek. Fix submitted upstream https://review.openstack.org/#/c/22540/ Verified NVR: openstack-packstack-2012.2.3-0.1.dev454.el6ost.noarch 1. Verified that 'tuned-adm active | grep virtual-host' returned no output. 2. Used packstack to install openstack. 3. Verified Active Profile again: # tuned-adm active | grep virtual-host Current active profile: virtual-host Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA.
