I think you should be able specify this within the ovirt-engine, just modify the cluster's cpu compatibility. I hit this too, but i think I just ended up provisioning the older machine first then the newer ones joined with the older model
1. first the host needs to have a compatible cpu model. what does 'vdsClient -s 0 getVdsCaps | grep -i flag' returns 2. cluster cpu level is easy, but hosted engine vm config resides on the disk, and needs to be manually edited in this case iirc.

Hello,
I am deploying hosted engine (HA) on hosts with different CPU models on one of my oVirt labs.
Host have different CPU's or there is also the problem: virtualization platform cannot detect CPU at all, "The following CPU types are supported by this host:" is empty:
2014-07-17 16:51:42 DEBUG otopi.plugins.ovirt_hosted_engine_setup.vdsmd.cpu cpu._customization:124 Compatible CPU models are: []
Is there any way to override this setting and use CPU of old machine for both hosts?
ex. host1:
cpu family : 6 model : 15 model name : Intel(R) Xeon(R) CPU 5160 @ 3.00GHz stepping : 11
host2:
cpu family : 6 model : 42 model name : Intel(R) Xeon(R) CPU E31220 @ 3.10GHz stepping : 7
