[Users] Ovirt does'nt recognize "Quad-core AMD Opteron" as Opteron

[Hideo GOTO]

Dear sirs,

We added a HP DL365-G5 server with 2 x "Quad-core AMD Opteron 2384" to
a working ovirt-node cluster ( CPU type of the cluster = "AMD Opteron
G3". Existing node servers use AMD Opteron 4284) . Then, the
Ovirt-engine refuses to intergrate DL365-G5, reporting an error of the
type: "CPU_TYPE_INCOMPATIBLE_WITH_CLUSTER".

Ovirt (RHEV) does'nt support AMD Opteron 2xxx series , though they are
KVM compatible? (This HP DL365 worked fine with VMWare).

Any solution, advise, comment is wellcome, since we do not much want
to revirt to VMWare.

FIY, On the ovirt-engine's node information, "CPU Name" is reported as
[N/A] and "CPU Type" as "Quad-Core AMD"

Here below is the content of the /proc/cpuinfo on the HP DL365-G5:

According to vdsClient's info as shown below, Quad-core Opteron  is
recognized as if it were a good old 32 bit CPU.
