is there anyway to know if your supposedly fully dedicated server is really a virtually resource-shared machine ?
I am wondering is there a way that I can determine which VPS software(Virtuozzo, Xen or OpenVZ) is used to implement the VPS which I am using.
On my box:
There are probably some similar traces of the virtualization solution you are using whichever it is.
It's almost always Xen, KVM, or ESX. You can usually look through the dmesg or hardware and figure it out pretty quick. Asking your hosting provider usually gets the answer too...
