This can only go in after the bug is fixed and possibly backported to all the
trees we care about. It won't pass osstest self pushgate otherwise.

It does more than just replacing the disc in cdrom. It also modifies
guest reboot action.

No functional change.

Previously an iso image that contains nothing was inserted to cdrom
after guest installation had finished.

With this patch we make cdrom really empty.  This helps catch bug that
prevents booting hvm guest with empty cdrom drive.

Remove empty iso image generation in ts-{debian-hvm,redhat}-install as
well.

I pushed these but they broke, but only with XSM.  See, for example:

  From: osstest service owner <osstest-admin@xenproject.org>
  To: <osstest-admin@xenproject.org>
  Subject: [osstest test] 95322: regressions - FAIL
  Date: Mon, 6 Jun 2016 19:29:51 +0000

  flight 95322 osstest real [real]
  http://logs.test-lab.xenproject.org/osstest/logs/95322/

  Regressions :-(

  Tests which did not succeed and are blocking,
  including tests which could not be run:
   test-amd64-amd64-xl-qemut-stubdom-debianhvm-amd64-xsm 9 debian-hvm-install fail REGR. vs. 93413
   test-amd64-i386-xl-qemut-stubdom-debianhvm-amd64-xsm 9 debian-hvm-install fail REGR. vs. 93413

I haven't had a chance to look at why, yet.  For now, I have dropped
these patches from the osstest push gate.

Thanks,
Ian.

I would say it is more related to stubdom.

libxl: error: libxl_dm.c:1967:stubdom_xswait_cb: Stubdom 4 for 3 startup: startup timed out
libxl: debug: libxl_event.c:686:libxl__ev_xswatch_deregister: watch w=0x219b2d8: deregister unregistered
libxl: error: libxl_create.c:1422:domcreate_devmodel_started: device model did not start: -9

I've put this on my list and will investigate further.

I know why.

The backend for empty CDROM is always in state 1. Mini-OS blkfront
refuses to move forward unless the backend status turns 4. See
mini-os.git blkfront.c:init_blkfront.

I'm not entirely sure how to fix it though.

Wei.
