Is there a way to install Alert Central in an existing VM? The problem is that the installation only offers options for VMWare or Hyper-V, but virtual machine setup is based on OpenStack. So is there an easy way to set this up on OpenStack or maybe install it on an existing Centos VM?
Alert Central is distributed as a virtual appliance, no other ways of it's install is supported.
You can try to run AlertCentral appliance in any Windows machine with Hyper-V support or using the free VMWare Player.
