Hi,

I looks like he is not using CPU feature levelling/masking, and his CPU does not support 
it ("maskable: no"). My guess he used the force option on pool-join to get 
these hosts into the same pool.
Yes, thats what I did.

I think XCP 1.5 checks whether the CPU features match on VM migrate, whereas 
previous versions did not do that. It would be nice though, if VM migrate would 
take pool-other-config:cpuid_feature_mask into account, so what Eugene tried 
would have worked. Currently this mask is only used for pool join.

Yes, this feature (use of pool-other-config:cpuid_feature_mask) would be very nice. While --force=true trick works in CLI, I can't live migrate VMs using XenCenter.

Hope it wouldn't be too hard to implement.

Thanks,
Eugene
