Hi All, The following patch set provides a low-overhead system for collecting kernel tracing data of guests by a host in a virtualization environment. A guest OS generally shares some devices with other guests or a host, so reasons of any problems occurring in a guest may be from other guests or a host. Then, to collect some tracing data of a number of guests and a host is needed when some

Hi Rusty, The linux-next kernel was failing my virtio-console test suite for a while. I looked into it today, and it's due to the virtqueue_add_buf() change that doesn't return > 0 values anymore. I found your commit that adjusts virtio_console.c, but you missed one instance where the return value mattered, and as a result not enough buffers were queued for the host to send in data.
