[libvirt] Unable to start a VM with USB device
Hi, I just packaged libvirt 0.7.7 for Debian. But I can't start a VM with an USB device attached: # virsh start test-vm error: Failed to start domain test-vm error: unable to set security context '107:113' on '/dev/bus/usb/000/000': No such file or directory I know there were changes about USB passthrough so I suppose it's a bug. Thank you, -- Laurent Léonard

Thank you,
Can you provide the VM XML? Thanks, Cole

No need, I screwed up. On domain startup, the security driver code is running before my code which resolves product/vendor to bus/device. I missed this because my test machine had the security drivers disabled.

How can I disable the security drivers for my virtual machine ? Could you send a patch to fix that issue ? Thank you, -- Laurent Léonard

Set security_driver='none' and user/group to 'root' in /etc/libvirt/qemu.conf Could you send
a patch to fix that issue ?
Dan is offline this week, I'll take a stab at fixing this. - Cole
