[Bug 639712] Re: PCI Pass Through via libvirt cannot remap IRQ's
Reboot did nothing, game over for now. The driver 'pci-stub' is occupying your device I thought pci-stub taking the device is what it was supposed to do? -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to qemu-kvm in ubuntu. https://bugs.launchpad.net/bugs/639712 Title: PCI Pass Through via libvirt cannot remap IRQ's -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs

OK, I've tried the following: 1) Recompile kernel with all the same options except enabling DMAR. 2) Edit the apparmour profile to match suggested by flashydave 3) Installed latest qemu-kvm from kvm edgers ppa: https://launchpad.net/~ubuntu-server-edgers/+archive/server-edgers-qemu-kvm Attached is the dmesg and log output. ** Attachment added: "dmesg" https://bugs.launchpad.net/ubuntu/+source/qemu-kvm/+bug/639712/+attachment/1820711/+files/dmesg -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to qemu-kvm in ubuntu. https://bugs.launchpad.net/bugs/639712 Title: PCI Pass Through via libvirt cannot remap IRQ's -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs

Found the apparmour errors in syslog, related to virt-aa helper. I added /sys/devices/** r, to usr.lib.virt-aa-helper and got a bit further.

Hmm, it seems thats actually because usb2 is not supported in KVM?

[Bug 545795] Re: apparmor driver blocks access to hostdev and pcidev devices
Rebooting the PC fixed that problem so I guess something hadn't been reloaded. I've also added /dev/** rwk, to the apparmour profile. Taking it away doesn't stop it from working again, although I've not tried rebooting the host yet. It still doesn't quite work however, as now (on the guest) I see this in lsusb: ja...@myth:~$ lsusb Bus 001 Device 002: ID 2040:9950 Hauppauge Bus 001 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub but in dmesg I see: [5.806567] dib0700: loaded with support for 13 different device-types [5.816285] dvb-usb: found a 'Hauppauge Nova-T 500 Dual DVB-T' in warm state.

[Bug 545795] Re: apparmor driver blocks access to hostdev and pcidev devices
Hi, I think I may also be having this problem, I'm trying to pass through a PCI WinTV NOVA T 500. It's actually a pair of USB DVB-T tuners on a PCI card so it needed the 'three stars' in the /sys path in the apparmour profile. I appended the improved solution: /sys/bus/usb/devices/ r, /sys/bus/usb/devices/** r, /sys/devices/**/usb[0-9]*/** r, But in the qemu log file I get: husb: open device 10.2 husb: config #1 need -1 husb: 1 interfaces claimed for configuration 1 husb: grabbed usb device 10.2 usb_linux_update_endp_table: Cannot send after transport endpoint shutdown Is this the same problem or have I found a new one? Googeling for that last line finds nothing! I also had to add this to get past the permission denied error: /dev/bus/usb/** rw, Would the output of 'find /sys/devices' be of any use?
