Bug 1303993

The <cpu id="... must correspond to the one defined in vdc_options. In this case it has to be "IBM POWER8" (e.g. without the space before the '8'). 

Does it work if you try it like this?

reply to comment 1:

It is regression as the rhevm env I am working on, contains active DCs and clusters, that were added via RESTAPI, about 2 month ago.

reply to comment 2:
Even when using "IBM POWER8" instead of "IBM POWER 8" still fails:
 
Using values from vdc_options ServerCPUList [1]:
-  <cpu id="IBM POWER8"/>           => fail same as in the bug description
-  <cpu id="Intel Conroe Family"/>  => succeed to add cluster

Ilanit - anything in the engine.log? (why is it not attached?)

The problem is that https://bugzilla.redhat.com/show_bug.cgi?id=1248867 seems to be partially incorrect. The part which updates the existing engine_config for 3.6 did not work due to incorrectly set default value for the fn_db_update_default_config_value() so it is still "IBM POWER 8".

And sending "IBM POWER 8" using REST does not work because there is a code which translates this to "IBM POWER8" on the API layer.

It is fixed for 4.0 and works for fresh install of 3.6.3.
For upgrade from 3.6.2 use a workaround to change the 'IBM POWER 8' to 'IBM POWER8' in the vdc_options table for the ServerCPUList for version 3.6. You can use a query like this:

update vdc_options set option_value = '3:Intel Conroe Family:vmx,nx,model_Conroe:Conroe:x86_64; 4:Intel Penryn Family:vmx,nx,model_Penryn:Penryn:x86_64; 5:Intel Nehalem Family:vmx,nx,model_Nehalem:Nehalem:x86_64; 6:Intel Westmere Family:aes,vmx,nx,model_Westmere:Westmere:x86_64; 7:Intel SandyBridge Family:vmx,nx,model_SandyBridge:SandyBridge:x86_64; 8:Intel Haswell-noTSX Family:vmx,nx,model_Haswell-noTSX:Haswell-noTSX:x86_64; 9:Intel Haswell Family:vmx,nx,model_Haswell:Haswell:x86_64; 10:Intel Broadwell-noTSX Family:vmx,nx,model_Broadwell-noTSX:Broadwell-noTSX:x86_64; 11:Intel Broadwell Family:vmx,nx,model_Broadwell:Broadwell:x86_64; 2:AMD Opteron G1:svm,nx,model_Opteron_G1:Opteron_G1:x86_64; 3:AMD Opteron G2:svm,nx,model_Opteron_G2:Opteron_G2:x86_64; 4:AMD Opteron G3:svm,nx,model_Opteron_G3:Opteron_G3:x86_64; 5:AMD Opteron G4:svm,nx,model_Opteron_G4:Opteron_G4:x86_64; 6:AMD Opteron G5:svm,nx,model_Opteron_G5:Opteron_G5:x86_64; 3:IBM POWER8:powernv,model_POWER8:POWER8:ppc64;' where option_name = 'ServerCPUList' and version = '3.6'

Verified on 3.6.1-0.1

(While using automation to build PPC testing rhevm environment from new, including add cluster, via REST API).
