SUMMARY

I created this ApacheCS installation on a virtual machine. I have it working and other hosts can connect to it. I realize now that ApacheCS instances virtual machines which would, in my case, cause nested virtualization of hosts. I have read that this does not work. Is ApacheCS able to work in this environment? I have not been able to find a real answer anywhere online, so I apologize for asking. I am not a Systems Administrator, only a student doing this as a project for my class.

@ThyLAW if you use a virtual machine as cloudstack kvm host, nested virtualization must be enabled.
however, it seems not supported by hyperv.
