[Xen-users] Intel integrated graphics VGA passthrough problem - I/O virtualisation disabled
Hello all,
I have already use xen for about a year. I use recently released Opensuse
11.3 (use Xen 4.0) for my experiment. I want to run 3D test in HVM(windows xp),
so I want to use VGA passthrough technology. But there is something not work
properly.
I google a lot of time, it says, I/O virtualisation should be enabled, but I
can solve it.
I run "xm dmesg" command, in the output, there is "(Xen) I/O
virtualisation disabled", what I should do to enable I/O virtualisation.
Can anyone help me?
motherboard verison is intel DG965RY.
Thank you!

[Xen-users] XEN 4/Squeeze: Dom0 FTP Killed by Bridge; SSH Works
Hey there, I''m using Xen 4 as per Debian Squeeze (Linux 2.6.32-5-xen-amd64, Xen 4.0.1-rc5). Dom0 is up and running with an IPTABLES firewall I successfully used on the bare hardware. The Firewall is pretty restrictive but allows for incoming SSH and outgoing FTP (FTP client functionality). However, outgoing FTP (FTP client functionality) is allowed by an ESTABLISHED, RELATED rule, rather than opening the FTP data port directly. This Firewall works perfectly well with exactly this script on the bare hardware, that is, apt-get works, and SSH works. Under Xen, with the peth0 bridge, SSH works, but passive FTP fails. The system has a single eth0 network card and uses the standard Xen bridging setup. The firewall rules are located in interface specific chains which are referencd from INPUT, OUTPUT and FORWARD by jumping to them after maching the device, as in -A IPNUT -i eth0 -j inp_eth0. I have played with forwarding and ip_forward settings and set the default FORWARD policy to ACCEPT but all that does not change a thing. BTW, I am wondering whether http://wiki.xensource.com/xenwiki/XenNetworking is correct; shouldn''t it read peth0 in the IPTABLES example? If you have the slightest idea what I may be missing here, any keyword/pointer/explanation would be highly appreciated. Thank you! -- Neu: GMX De-Mail - Einfach wie E-Mail, sicher wie ein Brief!

You need to look up the specifications of the processor and make sure VTd or IOMMU is supported on the processor. 2) Your BIOS must support it. There will be a setting in the BIOS, probably close to the standard Virtualization settings, for enabling I/O Virtualization (VTd, IOMMU). Check these things and make sure they''re configured correctly. -Nick -------- This e-mail may contain confidential and privileged material for the sole use of the intended recipient.

This page is community-maintained, so it''s up to folks who use these processors and motherboards to list them on the page. It''s quite likely that there are motherboards that support VTd not listed on that page, so you''ll want to check out your MB and possibly check with the manufacturer and see if the MB supports VTd. It''s also possible that just a BIOS update to your MB would allow it to support VTd. -Nick -------- This e-mail may contain confidential and privileged material for the sole use of the intended recipient.

nativesilent, Your motherboard and its chipset probably does not support VT-d.
