Hi,
for any of you who wants AMD EPYC support right now (its a hack, not proper tested!):
Michal, can we backport https://bugzilla.redhat.com/show_bug.cgi?id=1517286 to 4.2 avoiding people to do an hack? Tobias, just to be sure you noticed it, a respin of oVirt Node 4.2.3 absed on CentOS 7.5 has been released this morning.
1) Make sure your node and your engine are running under RedHat/CentOS 7.5
[root@ovirt ~]# cat /etc/redhat-release
CentOS Linux release 7.5.1804 (Core)
2) Get your PostgreSQL credentials
less /etc/ovirt-engine/engine.conf.d/10-setup-database.conf
3) Make the PostgreSQL libs available, so that we can start the PostgreSQL client later.
echo '/opt/rh/rh-postgresql95/root/lib64/' >/etc/ld.so.conf.d/postgresql_
opt.conf
4) Become PostgreSQL user.
su - postgres
5) Connect to the PostgreSQL database.
/opt/rh/rh-postgresql95/root/bin/psql -h localhost -p 5432 -U engine -W
6) Run the database update:
select fn_db_update_config_value('ServerCPUList', '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 Nehalem IBRS Family:vmx,nx,spec_ctrl,model_Nehalem:Nehalem,+spec-ctrl:x86_64; 7:Intel Nehalem IBRS SSBD Family:vmx,nx,spec_ctrl,ssbd,m odel_Nehalem:Nehalem,+spec-ctrl,+ssbd:x86_64; 8:Intel Westmere Family:aes,vmx,nx,model_Westmere:Westmere:x86_64; 9:Intel Westmere IBRS Family:aes,vmx,nx,spec_ctrl,model_Westmere:Westmere,+spec-ctrl:x86_64; 10:Intel Westmere IBRS SSBD Family:aes,vmx,nx,spec_ctrl,ss bd,model_Westmere:Westmere,+pcid,+spec-ctrl,+ssbd:x86_64; 11:Intel SandyBridge Family:vmx,nx,model_SandyBridge:SandyBridge:x86_64; 12:Intel SandyBridge IBRS Family:vmx,nx,spec_ctrl,model_ SandyBridge:SandyBridge,+spec-ctrl:x86_64; 13:Intel SandyBridge IBRS SSBD Family:vmx,nx,spec_ctrl,ssbd,model_SandyBridge:SandyBridge,+pcid,+spec-ctrl,+ssbd:x86_64; 14:Intel Haswell-noTSX Family:vmx,nx,model_Haswell-noTSX:Haswell-noTSX:x86_64; 15:Intel Haswell-noTSX IBRS Family:vmx,nx,spec_ctrl,model_ Haswell-noTSX:Haswell-noTSX,+spec-ctrl:x86_64; 16:Intel Haswell-noTSX IBRS SSBD Family:vmx,nx,spec_ctrl,ssbd,model_Haswell-noTSX:Haswell-noTSX,+spec-ctrl,+ssbd:x86_64; 17:Intel Haswell Family:vmx,nx,model_Haswell:Haswell:x86_64; 18:Intel Haswell IBRS Family:vmx,nx,spec_ctrl,model_Haswell:Haswell,+spec-ctrl:x86_64; 19:Intel Haswell IBRS SSBD Family:vmx,nx,spec_ctrl,ssbd,m odel_Haswell:Haswell,+spec-ctrl,+ssbd:x86_64; 20:Intel Broadwell-noTSX Family:vmx,nx,model_Broadwell-noTSX:Broadwell-noTSX:x86_64; 21:Intel Broadwell-noTSX IBRS Family:vmx,nx,spec_ctrl,model_ Broadwell-noTSX:Broadwell-noTSX,+spec-ctrl:x86_64; 22:Intel Broadwell-noTSX IBRS SSBD Family:vmx,nx,spec_ctrl,ssbd,m odel_Broadwell-noTSX:Broadwell-noTSX,+spec-ctrl,+ssbd:x86_64; 23:Intel Broadwell Family:vmx,nx,model_Broadwell:Broadwell:x86_64; 24:Intel Broadwell IBRS Family:vmx,nx,spec_ctrl,model_ Broadwell:Broadwell,+spec-ctrl:x86_64; 25:Intel Broadwell IBRS SSBD Family:vmx,nx,spec_ctrl,ssbd,model_Broadwell:Broadwell,+spec-ctrl,+ssbd:x86_64; 26:Intel Skylake Client Family:vmx,nx,model_Skylake-Client:Skylake-Client:x86_64; 27:Intel Skylake Client IBRS Family:vmx,nx,spec_ctrl,model_ Skylake-Client:Skylake-Client,+spec-ctrl:x86_64; 28:Intel Skylake Client IBRS SSBD Family:vmx,nx,spec_ctrl,ssbd,model_Skylake-Client:Skylake-Client,+spec-ctrl,+ssbd:x86_64; 29:Intel Skylake Server Family:vmx,nx,model_Skylake-Server:Skylake-Server:x86_64; 30:Intel Skylake Server IBRS Family:vmx,nx,spec_ctrl,model_ Skylake-Server:Skylake-Server,+spec-ctrl:x86_64; 31:Intel Skylake Server IBRS SSBD Family:vmx,nx,spec_ctrl,ssbd,model_Skylake-Server:Skylake-Server,+spec-ctrl,+ssbd: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; 7:AMD EPYC:svm,nx,model_EPYC:EPYC:x86_64; 8:AMD EPYC IBPB:svm,nx,ibpb,model_EPYC:EPYC,+ibpb:x86_64; 3:IBM POWER8:powernv,model_POWER8:POWER8:ppc64; 4:IBM POWER9:powernv,model_POWER9:POWER9:ppc64; 2:IBM z114, z196:sie,model_z196-base:z196-base:s390x; 3:IBM zBC12, zEC12:sie,model_zEC12-base:zEC12-base:s390x; 4:IBM z13s, z13:sie,model_z13-base:z13-base:s390x; 5:IBM z14:sie,model_z14-base:z14-base:s390x;', '4.2');
7) Exit PostgreSQL and the PostgreSQL user, restart the ovirt-engine
systemctl restart ovirt-engine
After that we are able to use the AMD EPYC processor model.

Keep in mind that next database update will overwrite the changes that you made, so maybe apply this again.
