After several months of hibernation tcm_vhost is making progress again - the goal is to get it functional and then evaluate the performance and features compared to QEMU SCSI emulation. These patches are small fixes that allow KVM guests to do I/O using the tcm_vhost fabric module from lio-core.git/master. I am submitting this as a baseline so others who have written patches on top of my personal tcm_vhost tree can start submitting directly to target-devel. Open issues with tcm_vhost: * The lio-core.git/master tcm_vhost and virtio_scsi drivers implement an old version of the virtio-scsi device specification. They are not compatible with the virtio_scsi driver which has been merged in linux.git. * The drivers/vhost/ infrastructure is tightly coupled to vhost_net; it's currently not possible to have vhost_net and tcm_vhost at the same time. * There are a number of TODO comments and #warn remaining in the code for code paths that have not yet been fleshed out.
