The Haswell cpu had a processor feature (hle, TSX-NI) that turned out to <br>
be flaky and Intel disabled this feature with a microcode update. <br>
<br>
The cpu's with the updated microcode no longer have the 'hle' feature in <br>
/proc/cpuinfo. oVirt/libvirt does not see the cpu as "Haswell" as the <br>
required feature is missing. <br>
<br>
Upstream libvirt has introduced "Haswell-noTSX" variants and oVirt will <br>
probably get a new CPU type to match in a future release. <br>
<br>
For now I've configured the CPU model as SandyBridge on my Haswell <br>
cpu's. <br>
<br>
I filed a bug about this in the oVirt bugzilla: <br>

Thanks for clarifying that! <br>
<br>
I had to go down to Intel Nehalem Family to get it working.<br>
