I've been helping clean up the english.  The authors are mostly Russian. 

As for your question, absolutely not.  There's pretty much nothing 
running on a VE that will affect the host at all.  Each VE has its own 
limits on memory, processes disk etc.  It uses native I/O and so unlike 
some of the other products, the I/O is not impacted by being 
"virtualized".  The individual VEs are very isolated from each other and 
the host.    There are a number of VPS vendors running OpenVZ or as Mike 
said, Virtuoso.
