From: Nicholas Bellinger <nab at linux-iscsi.org> This QEMU patch sets VirtIOSCSIConfig->max_target=0 for vhost-scsi operation to restrict virtio-scsi LLD guest scanning to max_id=0 (a single target ID instance) when connected to individual tcm_vhost endpoints as requested by Paolo. This ensures that virtio-scsi LLD only attempts to scan target IDs up to VIRTIO_SCSI_MAX_TARGET w...

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. Paolo Bonzini (2): virtio-scsi: create VirtIOSCSICommon vhost-scsi: new device supporting the tcm_vhost Linux kernel module hw/Makefile.objs

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
