From: Nicholas Bellinger <nab at linux-iscsi.org> Hi folks, This is the third RFC for vhost-scsi patches against mainline QEMU v1.1 to support the upstream tcm_vhost host virtualized target driver now available in v3.6-rc kernel code. This series is based upon last week's commit 346fe0c4c0b, and is aiming for a future QEMU v1.3 merge. The patch series is available directly from:

This is on top of Paolo and Nick's work. Current status: Works now (guest boots fine, no hang any more) with seabios's virtio-scsi disabled. Rebased to latest qemu.org/master Change details are in commit log. TODO: Make seabios happy.

This is on top of Paolo and Nick's work. Current status: Basically, tcm_vhost + seabios works now. We still have one more issue, vhost_verify_ring_mappings fails. The hotplug also works with the latest tcm_vhost.ko hotplug patch.

From: Nicholas Bellinger <nab at linux-iscsi.org> As requested by Anthony, here is a patch against target-pending/for-next-merge to expose an ABI version to userspace via a new VHOST_SCSI_GET_ABI_VERSION ioctl operation. As mentioned in the comment, ABI Rev 0 is for pre 2012 out-of-tree code, and ABI Rev 1 (the current rev) is for current WIP v3.6 kernel merge candiate code. I think this

In order to take advantages of Paolo's multi-queue virito-scsi, we need multi-target support in tcm_vhost first. Otherwise all the requests go to one queue and other queues are idle. This patch makes: 1. All the targets under the wwpn is seen and can be used by guest. 2. No need to pass the tpgt number in struct vhost_scsi_target to tcm_vhost.ko. Only wwpn is needed. 3. We can always pass
