+Some sort of virtualization appears to be present, but we are not sure

+should be, which would indicate virtualization. In this case, the

+
+You might use this program to tune an operating system so it runs
+better as a virtual machine of a particular hypervisor. However if
+installing paravirtualized drivers, it's better to check for the
+specific features your drivers need (eg. for the presence of PCI devices).
