Hi,
I got the error message as below when I tried to start the VM in Hyper-V 3.0. The VM is in a nested virtualization. The first hypervisor is ESXi 6.0 and the second one is Hyper-V 3.0. I have add guestOS="winhyperv" and hypervisor.cpuid.v0="False" and vhv.enable="TRUE" to .vmx file. Is there any other solution?
