SSO is depend on available of HW multi supervisor, here you config it in hyper-V so I think it not work.

I agree with @Mark Elsen - it is specifically mentioned in the doc which he linked so it should work fine. If it was not supported that would be stated in the restrictions and limitations. Always refer to the release notes and support matrix.
SSO is a software feature not a hardware feature so the hypervisor shouldn't be a factor.
The only difference, which applies to all hypervisors not just hyper-V, is the requirement for the 3rd interface for HA.
