The monitor/svm warnings and the lack of x2apic may be real issues, depending on the how the compat code on qemu-kvm-rhev works, thanks for catching it! This happens because qemu-kvm-1.5.3 doesn't have a mechanism for automatically disabling/enabling features when in KVM mode. I will work on a fix.
However, this doesn't prevent the CPU model from being used, so I suggest verifying this BZ and opening a new one that's not a FutureFeature BZ.
Since the problem described in this bug report should be
resolved in a recent advisory, it has been closed with a
resolution of ERRATA.
For information on the advisory, and where to find the updated
files, follow the link below.
If the solution does not work for you, open a new bug report.
