Gentoo Linux vm Processor Compatibility problem

[danievz]

Gentoo Linux vm doesn't want to regonise the "Processor Compatibilty" option in Hyper-v.When i highlight that option in Hyper-v the Gentoo linux doesn't want to boot.

model name : Intel(R) Xeon(R) CPU E5-2650 v4 @ 2.20GHz (Windows 2012 R2 machine)

model name : Intel(R) Xeon(R) CPU E5-2650 v2 @ 2.60GHz (Windows 2012 R2machine)

When the vm is running on the v4 machine it doesn't want to failover to the v2 machine and that is why i want to put "PROCESSOR COMPATIBILTY" mode on.

Thanks
