Stefano Garzarella 384c2561bd vhost-vsock: set vhostfd to non-blocking mode ... vhost IOTLB API uses read()/write() to exchange iotlb messages with the kernel module. The QEMU implementation expects a non-blocking fd, indeed commit c471ad0e9b ("vhost_net: device IOTLB support") set it for vhost-net. Without this patch, if we enable iommu for the vhost-vsock device, QEMU can hang when exchanging IOTLB messages. As commit 894022e616 ("net: check if the file descriptor is valid before using it") did for tap, let's use qemu_try_set_nonblock() when fd is provided by the user.
