virtio requests are scatter-gather-style descriptors, but no assumptions should be made about the layout. lguest was lazy here, but saved by the fact that the network device hands all requests to tun (which does it correctly) and console and random devices simply use readv and writev. Block devices, however, are broken: we convert to iovecs internally, just make sure we handle the correctly. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> |
