Some ability to run different OS distributions </li></ul></ul>Popular Ones <ul><ul><li>OpenVZ (Linux)
Linux-Vserver
FreeBSD Jails
Solaris Containers </li></ul></ul>

IO and Memory Performance levels similar to native operation
CPU Scalability - no &quot;virtual SMP&quot; limits
Resource Control and Constraints </li></ul></ul>Disadvantages <ul><ul><li>Guests must be same Kernel rev/arch as Host
“ Enterprise Functionality” is a mixed bag </li></ul></ul>
