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:
# dmesg | grep -i xen
Xen: 0000000000000000 - 0000000020800000 (usable)
Kernel command line: root=/dev/xvda xencons=tty console=tty1 console=hvc0 nosep nodevfs ramdisk_size=32768 ip_conntrack.hashsize=8192 nf_conntrack.hashsize=8192 ro
Xen reported: 2500.088 MHz processor.
xen_mem: Initialising balloon driver.
Xen virtual console successfully installed as tty1
xen-vbd: registered block device major 202
XENBUS: Device with no driver: device/console/0
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...
