Thanks for the clarification.
In this specific case v3 is a Haswell-noTSX while v4 is a Broadwell, with
the latter that has 6 more features (according to the cpu_map.xml )
So, I reckon an agent.properties set as follows would work:
guest.cpu.mode=custom
guest.cpu.model=Haswell-noTSX
Thanks agai

Page 76 explains it.. you want for CPU instructions sets to match and be
consistent if you plan to run v3 and v4 cpus in the same cluster.

At the end what matter are the CPU capabilities, meaning the instructions
tha can be used by operating systems (O.S) and their processes, in this
case, VMs can be considered processes in the hypervisor (hypervisors are

Hi Rafael,
in this case the hypervisor is KVM and I think it supports masking, but let
me check if I got it right:
if the CPU is not exactly the same the features can be masked using
hypervisor's capabilities.
Does it mean that if the CPU has the exact same features but different
frequency for e
It depends on your hypervisor.
For XenServer, you should check the CPU feature you have and if the CPU
supports masking [1].

Hi all,
quick but very important question: I have a cluster with Intel Xeon E5-2667
v3 CPUs and I need to add another host, but my provider has replaced the v3
with the v4 of the same CPU.
The differences are:
- Lithography (22nm > 14nm)
- Cache size (20MB > 25MB)
- Max Memory Bandwidth
