Product Management has requested further review of this request by Red Hat Engineering, for potential inclusion in a Red Hat Enterprise Linux Major release. This request is not yet committed for inclusion. The fix is in qemu-kvm-0.12.1.2-2.71.el6 You should be able to verify this from libvirt now Red Hat Enterprise Linux Beta 2 is now available and should resolve the problem described in this bug report. This report is therefore being closed with a resolution of CURRENTRELEASE. You may reopen this bug report if the solution does not work for you.
