Out of curiosity, what is the technology that a VDS uses? I know about 'classic' VPS technology like Xen/Virtuozzo/VMWare etc, but am not across how a VDS may be implemented.
I have seen a few hosts implementing what they call 'VDS', sometimes on even cheapo $3.95/ month shared accounts, and wondered what it really meant and how it was implemented.
Is it just another name for process and privilege isolation (eg jailing and suexec?) rather than complete memory/disk/CPU etc compartmentalization?
