Please give the VitalPBX iso the ability to be installed under Hyper-V as a Gen2 vm. Many businesses utilize Hyper-V and need Gen2 features. We are able to do this with our FreePBX distro PBX’s that we install.
We have only tried it successfully in Gen 1, we also tried to install minimal 7 centos in gen 2 and it was not possible. If you can install the Centos 7 in Gen 2, you can perfectly use the VPS scripts to install VitalPBX later.
