I had used to run OST inside a VM even this year, but switched to bare
metal to make it run a bit faster. There were some problems with CPU
configuration, but only on cluster initialization, not that soon. I
didn't run HE tests though.

Yes, it's the very first thing to check.
Now pushed a simple patch to use Westmere cpu model:
https://gerrit.ovirt.org/85443
With it, it at least did not refuse to start - although it's only
in the beginning now, didn't yet start actual HE deploy or try to
start the engine vm.
Should I expect any significant issues with this patch?
