Hi! I have a problem with i7 and vt-d. xm dmesg shows: (XEN) I/O virtualisation disabled but I have activated it in BIOS... what can be the problem?

Try kernel-parameter iommu=1 in your dom0 boot-script. something like this: kernel /xen-3.3.1.gz console=vga dom0_mem=512M iommu=1 In older xen-versions vtd=1 did the same. This option seems to be not so well documented... It took me some hours to find and hopefully understand them.

Yep it works but I have some strange msgs in xm dmesg: (XEN) I/O virtualisation enabled (XEN) I/O virtualisation for PV guests disabled (XEN) [VT-D]iommu.c:1269:d32767 domain_context_mapping:invalid (XEN) [VT-D]iommu.c:1269:d32767 domain_context_mapping:invalid (XEN) [VT-D]iommu.c:1269:d32767 domain_context_mapping:invalid (XEN) [VT-D]iommu.c:1269:d32767 domain_context_mapping:invalid (XEN) [VT-D]iommu.c:1269:d32767 domain_context_mapping:invalid (XEN) [VT-D]iommu.c:1269:d32767 domain_context_mapping:invalid (XEN) [VT-D]iommu.c:1269:d32767 domain_context_mapping:invalid (XEN) [VT-D]iommu.c:1269:d32767 domain_context_mapping:invalid (XEN) [VT-D]iommu.c:1269:d32767 domain_context_mapping:invalid (XEN) [VT-D]iommu.c:1269:d32767 domain_context_mapping:invalid What does it mean?

So, shutdown the PC, and pull the power cable out (just to be sure) and then try again -- Kind Regards Rudi Ahlers CEO, SoftDux Hosting Web: http://www.SoftDux.com Office: 087 805 9573 Cell: 082 554 7532 _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
