Encontrei mais um aqui[0] e uma explicação sobre a diferença entre xen/vserver. Segue abaixo para quem tiver interesse: Adv of Xen over VServer: * Stronger isolation * Stronger accounting * Heterogeneous guests * Live migration Adv of VServer over Xen: * Very simple to manipulate guest filesystems * Maximal resource sharing * Don't have to "preallocate" disk space and memory space * Even lower performance penalty (though for many workloads it won't make much / any difference) Similar arguments apply to Solaris Zones and FreeBSD Jails (both of which are similar to VServer) in functionality. > What advantage does Vserver have compared to Xen ??? why should it make > sense to use both? Vserver makes it possible to share on-disk and in-memory the footprint of a given program between separate contexts. The kernel being shared, if you make your different contexts with hardlinks "copies" of the files, you can have the same code of libc, damemons, ... loaded only once in memory, only the "data" part of memory allocated is charged for each virtual server. So, you get virtual servers that are very efficient on memory and disk usage. On the other hand, you get less control on the allocation/limitation of ressources used (memory, cpu, ...) and since you have all contexts running in the same kernel a potential security hole ine the kernel would be open to every of the virtual servers.
