Hi,

I remake my scripts.
I found dmidecode sometimes don't work on HVM domain
and it is not installed on default system of some distribution.
So I use /proc/acpi/dsdt.
Please comments.

===================================================================
#!/bin/bash

IS_X86HVM="$(strings /proc/acpi/dsdt | grep int-xen)"
if [ x"${IS_X86HVM}" != x ]; then
        echo "this is x86 hvm machine"
elif [ -f /proc/xen/capabilities ] ; then
        if $(grep -q control_d /proc/xen/capabilities); then
                echo "this is dom0."
        else
                echo "this is domU."
        fi
else
                echo "this is native machine"
fi
===================================================================
