Better you check the value of /sys/hypervisor/uuid. If it's all zeros, 
then it would be dom0, otherwise a paravirtualized domU.  To check 
whether it's a fully virtualized guest or not, you need to check the 
output of "dmidecode" from within the guest. An HVM guest's dmidecode 
should show as below
Handle 0x0100
       DMI type 1, 27 bytes.
       System Information
               Manufacturer: Xen
