Well, they run on the same OS kernel as the host system, but allow multiple Linux variants in individual containers. The single-kernel implementation enable running containers with much less overhead. Hence, OpenVZ offer higher efficiency and management than traditional virtualization technologies. It uses a single patched Linux kernel, and as a result can run only linux and doesn’t have the overhead of a hypervisor (a tiny part of CPU resources is used on virtual section -around 1-2 %),it’s faster & efficient.</span></span></span></div><div align="LEFT" class="western" style="margin-bottom: 0cm;"><span style="font-family: Georgia, Times New Roman, serif;"><br /></span><br /><span style="font-family: Georgia, Times New Roman, serif;"><br /></span> <br /><div class="separator" style="clear: both;
