How cloudstack make a choice between two or more "same function" plugins ?

[ChunFeng <ch...@domolo.com>]

Hi all,




    I know that CloudStack has 40+ plugins available for use , and I had already write some of my own version's dummy plugin for study purpose .


    Such as , I write my own version of  cloud-plugin-hypervisor-kvm plugin . 


    Now the question is comming in ,  How cloudstack make a choice between two or more "same function" plugins ?  Should I assign some "Flag" in global options , just like : Host Random Allocator does ?  


    If I put some config item in global options , which means , I had to modify cloudstack framework to let cloudstack aware that config item .  And I thought this is not the "plugin way" to extend cloudstack functionality . 


    Any suggestions ?
