Hi Christian,

Has the Dom0 kernel CONFIG_TUN enabled? If so, is TUN/TAP working?
No it isn't. How do I enable it? The default "make world" doesn't seem
to do that
However:
make linux-2.6-xen-config CONFIGMODE=menuconfig
as in 2.6.18 does not work as its downloading the 2.6.18 kernel then. Is
there any documentation how to conmpile a custom kernel with xen 4 and
2.6.31?
For VTd I found out the following:
xm dmesg:
(XEN) [VT-D]dmar.c:679: Host address width 36
(XEN) [VT-D]dmar.c:694: found ACPI_DMAR_DRHD:
(XEN) [VT-D]dmar.c:398: dmaru->address = feb00000
(XEN) [VT-D]dmar.c:334: endpoint: 0:1b.0
(XEN) [VT-D]dmar.c:694: found ACPI_DMAR_DRHD:
(XEN) [VT-D]dmar.c:398: dmaru->address = feb01000
(XEN) [VT-D]dmar.c:334: endpoint: 0:2.0
(XEN) [VT-D]dmar.c:334: endpoint: 0:2.1
(XEN) [VT-D]dmar.c:447: Non-existent device (0:2.1) is reported in
this DRHD's scope!
(XEN) [VT-D]dmar.c:469: The DRHD is invalid due to there are devices
under its scope are not PCI discoverable! Pls try option iommu=force or
iommu=workaround_bios_bug if you really want VT-d
(XEN) Failed to parse ACPI DMAR. Disabling VT-d.
When I set iommu=force then vtd will be enabled but what should I do to
solve this better?
Thank you and best Regards
Ralf
