[Xen-devel] [RFC] Is this process running on which machine?

[Akio Takebe <takebe_akio@xxxxxxxxxxxxxx>]

Hi, all

I'd like to know "Is this process running on which machine?"
For example, a native machien, or dom0, or domU, or HVM..

So I research codes of xen,
then I make the following shell.
(I haven't confirmed HVM yet because I don't use VTx machine.)
What do you think about it?

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

if [ -d /sys/hypervisor ] ; then
        UUID=$(cat /sys/hypervisor/uuid)
        if [ x"$UUID" == x"00000000-0000-0000-0000-000000000000" ]; then
                echo "this is dom0."
        else
                echo "this is domU."
        fi
else
        IS_HVM=$(strings /proc/acpi/dsdt | grep -i xen)
        if [ x"IS_HVM" != x ]; then
                echo "this is hvm machine"
        else
                echo "this is native machine"
        fi
fi
=========================================================================

Best Regards,
