I also have the same problem: USB host devices can no longer be added to the guest system. I don't use USB redirection with spice, but the Add hardware -> USB host device option in virt-manager. I get the following messages in the /var/log/libvirt/qemu/guest.log file:
libusbx: error [_get_usbfs_fd] libusbx couldn't open USB device /dev/bus/usb/001/011: Permission denied libusbx: error [_get_usbfs_fd] libusbx requires write access to USB device nodes. Sure enough, the write permissions are restricted to root only: crw-rw-r-- 1 root root 189, 11 marra 4 12:00 011 Shouldn't libvirtd change these permissions automatically? This worked in 14.04, so it is a regression. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1387154 Title: USB host device no longer added to VM To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libvirt/+bug/1387154/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
