Hi MST & Paolo,
Here are the associated QEMU vhost/scsi changes to enable KVM host
for expose F_HOTPLUG, F_T10_PI, and ANY_LAYOUT feature bits into
virtio 1.0 compatible guests.
Note this does not include VIRTIO_SCSI_F_CHANGE, which is currently
not supported by vhost/s

Hi Yan,
So recently I've been doing some KVM guest performance comparisons
between the scsi-mq prototype using virtio-scsi + vhost-scsi, and
Windows Server 2012 with vioscsi.sys (virtio-win-0.1-74.iso) +
vhost-scsi using PCIe flash backend devices.
I've noticed that small block random performance

Hi Paolo & Co,
So I've been running into another bug with SeaBIOS w/ virtio-scsi +
vhost-scsi-pci code..
During the last weeks debugging on the QEMU vhost memory re-mapping bug,
my seabios builds have been using a smaller target ID (16) for scanning
than the default hard coded value of 256 in ini

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.
This ensures that virtio-scsi LLD only attempts to scan tar

The path to /dev/vhost-net is currently hardcoded in vhost_dev_init().
This needs to be changed so that /dev/vhost-scsi can be used. Pass in
the device path instead of hardcoding it.

This patch adds a new type of host device that drives the vhost_scsi
device. The syntax to add vhost-scsi is:
qemu -vhost-scsi id=vhost-scsi0,wwpn=...,tpgt=123
The virtio-scsi emulated device will make use of vhost-scsi to process
virtio-scsi requests inside the kernel

This patch renames+moves the net_handle_fd_param() caller used to
obtain a file descriptor from either qemu_parse_fd() (the normal case)
or from monitor_get_fd() (migration case) into a generically prefixed
monitor_handle_fd_param() to be used by vhost-scsi code.

This patch starts and stops vhost as the virtio device transitions
through its status phases. Vhost can only be started once the guest
reports its driver has successfully initialized, which means the
virtqueues have been set up by the guest.

Hello Anthony & Co,
This is the fourth installment to add host virtualized target support for
the mainline tcm_vhost fabric driver using Linux v3.6-rc into QEMU 1.3.0-rc.
The series is available directly from the following git branch:

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

This patch fixes bug in the definition of VirtIOSCSI->cmd_vqs[0],
where the return of virtio_add_queue() in virtio_scsi_init() ends up
overwriting past the end of ->cmd_vqs[0].
Since virtio_scsi currently assumes a single vqs for data, this patch
simply changes ->cmd_vqs
