[Bug 1891214] Re: targetcli/LIO needs tcm_vhost and xen-scsiback feature enabled OR option disabled

[Christian Ehrhardt ]

Hi Rafael,

on the qemu side I think we are ready,
we have
  CONFIG_VHOST_USER=y CONFIG_VHOST_KERNEL=y
already and also virtio-scsi already enabled.
  vhost-net support yes                                                            
  vhost-crypto support yes                                                         
  vhost-scsi support yes                                                           
  vhost-vsock support yes                                                          
  vhost-user support yes                                                           
  vhost-user-fs support yes 

I think we are good with that as-is.

If you happen to find anything you need changed in qmeu let me know, but
until then I'll keep this as incomplete.

** Changed in: qemu (Ubuntu)
       Status: New => Incomplete

Title:
  targetcli/LIO needs tcm_vhost and xen-scsiback feature enabled OR
  option disabled

Status in linux package in Ubuntu:
  Confirmed
Status in python-rtslib-fb package in Ubuntu:
  Confirmed
Status in qemu package in Ubuntu:
  Incomplete

Bug description:
  targetcli-fb was recently included in MAIN and rely on some features
  that aren't available currently in Ubuntu:

  ## TCM VHOST

  /vhost> create
  b'modprobe: FATAL: Module tcm_vhost not found in directory /lib/modules/...

  not enabled in Ubuntu kernels.

  QEMU virtio-scsi feature:

  https://wiki.qemu.org/Features/VirtioSCSI/TCM_Overview

  KERNEL option to be enabled:

  https://cateee.net/lkddb/web-lkddb/TCM_VHOST.html

  KERNEL TCM documentation:

  https://www.kernel.org/doc/html/latest/target/tcmu-design.html

  LIO (LinuxIO) VHOST feature explained:

  http://linux-iscsi.org/wiki/VHost

  ## XEN PVSCSI

  Same happens for XEN:

  https://wiki.xenproject.org/wiki/Paravirtualized_SCSI

  PS: this would I would go for a targetcli fabric module disablement
  instead of enabling the feature.
