VDSM now uses tuned profiles for virtual hosts. Upon host installation, the installation script changes the host profile to 'virtual-host', which optimizes host performance. Note that the tuning is done only once, so it is not suitable for dynamic systems.

(In reply to comment #0) > Description of problem: > 1. VDSM should depend on tuned package. > 2.

'enterprise-storage' gives worse performance than what we are currently using. Perf team has an rfe to create a 'virt' profile and once that's done (hopefully rhel 6.3), we should use it. keeping open because the general idea of using tuned is correct. > > > Version-Release number of selected component (if applicable): > > > How reproducible: > > > Steps to Reproduce: > 1. > 2. > 3. > > Actual results: > > > Expected results: > > > Additional info: (In reply to comment #1) > (In reply to comment #0) > > Description of problem: > > 1.

Yaniv, why does this bz (host profile) depends on bug 740977 which is the guest one? (In reply to comment #3) > Yaniv, why does this bz (host profile) depends on bug 740977 which is the > guest one? No idea, removed the dependency. *** Bug 838440 has been marked as a duplicate of this bug. *** Minor update: the hypervisor now has virt-host profile. So this is what bootstrap will apply. bootstrap rewrite support tuned. Ayal, what's our stance on changing this from a support point of view (read: should changing the tuned profile on the hosts in a RHEV environment be documented in the RHEV documentation)? For now on the basis that I have created a documentation clone to reflect the need to name check this and refer readers to the RHEL Performance Tuning Guide for more information about the profiles I am setting docs_scoped+.
