Nested Virtualization/Hypervisor ESXi => HyperV….
To run HyperV in ESXi modify the vmx file of the HyperV guest vm:
vhv.enable = "TRUE"
hypervisor.cpuid.v0 = "FALSE"
To allow network communication from VMs on the HyperV over the HyperV virtual switches to the ESXi network the “Promiscuous Mode” of the ESXi network switch has to be set to “Accept” – ESXi-Host => configuration => networking => select vSwitch<X> => properties => select vSwitch => Edit => Security => Policy Exceptions => Promiscuous Mode => Accept

WinCC OA Android App…
I now also built an Android App to visualize my Home-Automation data (powered by WinCC OA – www.etm.at).
Because i did the same for iOS and used C# for coding (Xamarin Framework) i was able to share about 70% of the code between both Apps (iOS and Android). So there was no need to re-implement the communication and business logic!! All i had to do is to get familiar with the Android-UI…
