Category: kernel Group: None Status: Open Resolution: None Priority: 5 Private: No Submitted By: Mike Coss (mjcoss) Assigned to: Nobody/Anonymous (nobody) Summary: kvm hangs when iommu used Initial Comment: CPU: Intel i7 975 Extreme Edition Host: Gentoo w/2.6.31-rc6 kernel 32bit Guest: Windows XP sp3 32bit I'm trying to use Vt-d to enable pci pass through of a Nvidia GTX 295 card, and I currently have 2 issues. The first is that when I shutdown the kvm, the process hangs. It can't be killed, and it uses 100% utilization of the cpu that it's running on. As expected, it prevents the system from shutting down and I have to reset the machine. The second issue is that when I start the kvm, I get an error message Option ROM size fe00 exceeds available space Option ROM size fe00 exceeds available space If I don't try to use pass through the KVM starts and stops fine. Under windows, it sees the GTX 295, and allowed me to install the driver, but it fails to start with error message that it doesn't have enough resources to start. I have tried kvm-88, and the latest qemu-kvm-0.11.0-rc1. I have also tried it with a Linux distribution, OpenSUSE, and the X server doesn't start, however I do get a message from the driver that I'm still tracking down. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=893831&aid=2844286&group_id=180599 -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
