I did not mean KVM required a special kernel just that guests need a full kernel install to run so it is more heavy than a container approach. Also disk and overall performance is in no way as good as a container approach. If you do not believe me try compiling kde, a kernel or some other large library in any of these then do the same in a container. I have found that this takes 2 to 5 times longer in xen, vmware, virtualbox,kvm on good modern hardware with the hardware virtulization acceleration enabled versus the real hardware and only a few percent longer in a container.


Ofcourse, there's no objection to that. I found myself preferring KVM to Openvz for other, pure egoistic reasons - i don't run into upgrade issues with customers for one. Every time someone does a "do-release-upgrade" in ubuntu in an openvz container, i have to fix it after him, after hearing thousands of complaints about it Very Happy
