I'm not sure, but I don't think so. I would use OpenVZ or Virtuozzo instead.

I don't know that many resources regarding this information. I saved a
pdf from an "Intel Cloud Builder Series" webcast in 2010, that
featured Parallels Virtuozzo. It says they deployed 120 virtual
environments on a single 16 GB RAM host. All 120 virtual environments
ran the DVD-Store LAMP Stack (I don't know, whether this is this
DVD-Store (http://linux.dell.com/dvdstore/)) and the latency grew
unbearable at around 120 VEs.

You should look into OpenVZ/Virtuozzo, if you want to start know.
Otherwise you'll have to wait until all the new stuff (e. g. Criu
(criu.org)) have found their way into the main kernel.
