I posted a script (a while back) to get oVirt running on Centos hosts.

One of the items in it has to do with what "tuned" profile to use= =3D . At the time I first ran into it, this was a fatal error. It i= =3D s now just a warning, so it does not prevent installing a host. But, = =3D as a warning, a lot of people are probably missing it.

When using Centos 6 as the host OS, the script tries to install a "rhs= =3D -virtualization" profile. That profile is not included in Centos= =3D . I substituted the "virtual-host" profile.

I believe that this may be a regression as a result of Bugzilla 987293, where "rhs-virtualization" was substituted for= =3D "virtual-host" for RHEV + RHS. I am guessing that what= =3D ever is used as a switch to determine RHEV + RHS is also shoving Centos= =3D into that same path, which is not appropriate.

My suggestion would be to write the script so that it uses "rhs-virtua= =3D lization" when present, and if it is not present, then it falls back t= =3D o "virtual-host". (I don't know what (if any) differences t= =3D here are between the two profiles.)

Should I open a new bug, make a comment on 987293, or take some other path?= =3D
