David Stevens 4257919fa7 devices: vvu: poll when opening vvu device ... Launching a VVU device requires access to /dev/vfio/$vfio_group. The permissions on those files can't be set by upstart, since the files don't exist until a vvu device process binds its vvu pci device to vfio-pci. Instead, the permissions are set via udev rules. Unfortunately, there is no good way to wait for udev to modify the permissions, so the device process just needs to poll until it is successfully able to open its device.
