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: 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. Asias He (1): disable vhost_verify_ring_mappings check Paolo Bonzini (2): virtio-scsi: create VirtIOSCSICommon vhost-scsi: new device supporting the

From: Nicholas Bellinger <nab at linux-iscsi.org> Hi QEMU folks, The following is the patch series to support vhost-scsi-pci within the upstream QEMU tree. This includes the refactoring of existing virtio-scsi code from Paolo to allow a VirtIOSCSICommon structure that is shared amoungst existing virtio-scsi-pci device and new vhost-scsi-pci device code. Currently this code requires

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.

From: Nicholas Bellinger <nab at linux-iscsi.org> Hi Anthony, Here are the two patches against Zhi's vhost-scsi tree to check for a supported version (VHOST_SCSI_ABI_VERSION=1) that's now exposed via the tcm_vhost ioctl. Please have a look and let me know if this is what you had in mind. Thanks! Nicholas Bellinger (2): vhost-scsi: Rename vhost_vring_target ->

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
