Maybe this is a problem with ovirt-host-deploy, it must be configured to avoid overwriting your vdsm.conf file. There are instructions in the wiki:

Hi,
I tried to test various engine features related to PPC support, However since I don't have a real Power PC HW I tried using the fake PPC configuration introduced by http://gerrit.ovirt.org/#/c/18718
So I added the following configuration to /etc/vdsm/vdsm.conf on a x86_64 host:
fake_kvm_support=true fake_kvm_architecture=ppc64
And indeed it looked successful as you can see below
[root@bazulay1 ~]# vdsClient -s 0 getVdsCaps | grep -i cpu cpuCores = '4' cpuFlags = 'powernv,model_POWER7_v2.3' cpuModel = 'POWER 7 (fake)' cpuSockets = '1' cpuSpeed = '3401.000' cpuThreads = '8'
However after creating the appropriate cluster: CPU Architecture = ppc64 CPU name = IBM POWER 7* (meaning I tried all IBM POWER 7... cpus)
Adding the host always ended in non operational status with the error:
"Host bazulay1 has architecture x86_64 and cannot join Cluster TESTDAY-CLUSTER which has architecture ppc64."
Thanks Barak Azulay
