In "POSIX-like" guests, you can dump the ACPI tables with the "acpidump"
utility (pmtools package), eg.
acpidump --table DSDT --output DSDT.aml --binary
then decompile it with "iasl":
iasl -d DSDT.aml
This creates "DSDT.dsl", a decompiled ACPI Source Language file. You can
interpret it by consulting the ACPI specification
<http://www.acpi.info/spec50.htm>.
