This is based on :

which I had to first "hand massage" to get to apply and then had to
make a couple of adjustments in order to compile.  Since the review,
Fritz responded directly to me and I've exchanged some thoughts back
to him as I dug deeper into the issue.

Patches 1 & 2 are related to the problem insomuch as the iscsi code
will first try to "see" if a client connection already exists and if
so, it won't try to recreate one. If one doesn't exist, then it will
try to create one. So in a way it actually expects an error for a
couple of paths. That error would be splatted out (in my case in
the window I was running libvirtd in debug mode). So the patches
make it so one can get an exitstatus and error buffer if they so
choose when running the virCommandRunRegex

Patches 3-6 are essentially a step by step rework of Fritz's patch
with one change.  In Fritz's patch the model was to remove the big
hammer approach taken to set the "node.startup" to "manual" for every
target found for the portal (e.g. the <ipaddr:port>). My approach alters
that by only setting "node.startup" to "manual" for any target which
libvirt manages via an iSCSI storage pool. I think that keeps the
spirit of the original change (commit id '3c12b654') in tact while
also making sure to not set "manual" mode on targets libvirt doesn't
manage.

Fritz Elfert (1):
  util: Add "--op nonpersistent" to iSCSI sendtargets

John Ferlan (5):
  util: Add exitstatus parameter to virCommandRunRegex
  iscsi: Add exit status checking for virISCSIGetSession
  iscsi: Export virISCSITargetAutologin
  iscsi: Inhibit autologin for only libvirt managed targets
  iscsi: Remove initiatoriqn from virISCSIScanTargets
