Doc Type: Bug Fix
Doc Text:
Using "Opteron" CPU options with Red Hat Enterprise Linux (RHEL) 6 machine types caused the QEMU emulator to terminate unexpectedly due to a typographical error in one of device names. This update corrects the error so "Opteron" CPU options can be used with RHEL 6 machine types as expected.

confirmed to affect all rhel-6 based machine types

Francesco, can you check if qemu-kvm-ev currently in -snapshot is ok so you can move this bug to modified?

It is:

Fixed in version: qemu-kvm-rhev-2.6.0-28.el7_3.3

http://resources.ovirt.org/pub/ovirt-4.1-snapshot/rpm/el7Server/x86_64/qemu-kvm-ev-2.6.0-28.el7_3.3.1.x86_64.rpm

but the patch bumping the spec is not yet merged or backported.
Comment 5 Sandro Bonazzola 2017-01-25 07:54:22 UTC 
4.0.6 has been the last oVirt 4.0 release, please re-target this bug.

nope, still POST
Comment 8 Francesco Romani 2017-02-02 14:06:49 UTC 
In branch 4.0.z we still depend on QEMU >= 2.3.0 (https://github.com/oVirt/vdsm/blob/ovirt-4.0/vdsm.spec.in#L256). The Opteron_G4 issue AFAIU affects QEMU 2.6.z, so what to do here? Should we bump the dep to >= 2.6.0 also on branch 4.0.z?

I can answer myself.
The regression was introduced during one 2.6 rebase, it is not present in the 2.3.0 codebase.
Thus, the only vulnerability in the 4.0.z branch is on RHEL7.3, and only if one user manages to update to the buggy version of qemu, but this will be automatically fixed when yum -y update is run again.

Thus, we don't need patches to 4.0.z branch.

THe patch was merged on master and ovirt-4.1 branch, so we can move to MODIFIED.
