I'm purchasing a Plesk 12 licence, and the provider is requesting the VPS platform the licence will be used on. The options are;

• Virtuozzo
• KVM
• XEN
• VMWare
• MicroSoft Hyper-V
• Parallels Server
• OpenVZ

Does it matter which I choose?

I already have Plesk 12 installed and running a demo licence from Parallels on my Droplet. They didn't ask which platform.
