Thanks. That's what I suspected. In my particular setup each guests uses its own LV to run pretty much separate software so apart from kernel and maybe basic binaries there might not be much sharing going on anyway. > > > > 2.

Also their answer to the "Why isn't there a device /dev/xyz within a guest?" question in the FAQ (http://tinyurl.com/4y8mhc) isn't encouraging for anyone concerned about enough segregation between the guests. Even though I control all software on the physical server I'd rather try to have better separation separate among the guests. > > Coupled with the fact that there was no stable release since kernel 2.6.22, > I would recommend to avoid the vserver technology for the time being.

But I'm restricted to CentOS and being aware (but not familiar) with the Debian packages triggered my question about CentOS.
