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

[Hideo GOTO]

Dear Yaniv Kaul,

Thanks for your propmt anwer.
It seems that your patience did not allow your reading to continue
after "CPU_TYPE_INCOMPATIBLE_WITH_CLUSTER".

As reported in the last part of my previous mail, the output from
vdsClient shows us that the processor is recognised as none of AMD
Opteron G1, G2 or G3 (cpuFlags=...) . Thus, Quad-core AMD 2384 cannot
match any of  Ovirt CPU type options. For confriming, I have just
tried, upon reciept of your reply, to add the host to cluster of other
CPU types (G1, G2 ..) , to get the same unfortunate result.

For your comparaison, here-below shows the "cpuFlags"  reported for an
AMD Opteron 4284, which Ovirt can treat as either of AMD Opteron G3,G2
and G1 :
