ANNOUNCE: oz 0.8.0 release

[Chris Lalancette]

All,
     I'm pleased to announce release 0.8.0 of Oz.  Oz is a program for
doing automated installation of guest operating systems with limited
input from the user.
     Release 0.8.0 is a (long overdue) bugfix and feature release for
Oz.  Some of the highlights between Oz 0.7.0 and 0.8.0 are:

     - Optional virtualenv make target
     - Conversion of unittests to py.test
     - Replace mkisofs with genisoimage
     - Debian package
     - Ability to change the root password for Debian installs
     - Add unittests for ozutil
     - Add some unittests for the Guest object
     - SSH tunnel (with SSL vhost) support for local repositories
(mostly useful for imagefactory)
     - Add a new manpage for oz-examples
     - Make the output filename configurable with a command-line
option to oz-install
     - Monitor both network and disk activity when looking for guest activity
     - Support for installing Ubuntu 11.10
     - Support for SSL certificates for repositories
     - Support for an optional version in the TDL
     - Support for installling Mandrake 9.1, 9.2, 10.0, 10.1, 10.2
     - Support for installing Mandriva 2006.0, 2007.0, 2008.0
     - Support for Ubuntu customization
     - Support for installing RHEL 6.2

     A tarball of this release is available, as well as packages for
Fedora-16.  Instructions on how to get and use Oz are available at
http://aeolusproject.org/oz.html

     If you have any questions or comments about Oz, please feel free
to contact aeolus-devel(a)lists.fedorahosted.org or me
(clalancette(a)gmail.com) directly.

     Thanks to everyone who contributed to this release through bug
reports, patches, and suggestions for improvement.

The links to 0.8.0 haven't been added at the above URL.
I found Fedora _15_ rpms on fedorapeople which installed fine on F16.

There seems to be some issue with error timeouts on this version.
I first tried to create an image without enough free space:

oz-install -t 50000 -u -d3 -x blah.xml /var/lib/pacemaker-cloud/jeos/F16-x86_64-jeos.tdl
This hung at "cleaning up" phase _forever_. strace says hung at:
    sendto(14, "var/lib/oz/isocontent/F16-x86_64"..., 1585278, 0, NULL, 0^C
<unfinished ...>
Ctrl-c unlocked after which got:
    94.60% done, estimate finish Fri Jan 13 18:52:46 2012
    genisoimage: No space left on device. cannot fwrite 32768*1

So after freeing up enough space I tried again and got farther.
However this also hung forever at the "Unmounting all" stage.
This only happens if "customizing image", and only with SELinux on.
strace says: recvfrom(14,...
Anyway apart from the SELinux issue, I got out of the infinite wait with
Ctrl-C and it then proceeded to timeout as expected.
    File "/usr/bin/oz-install", line 162, in <module>
        guest.customize(libvirt_xml)
    File "/usr/lib/python2.7/site-packages/oz/RedHat.py", line 1169, in
customize
        return self._internal_customize(libvirt_xml, False)
    File "/usr/lib/python2.7/site-packages/oz/RedHat.py", line 1150, in
_internal_customize
        guestaddr = self._wait_for_guest_boot(libvirt_dom)
    File "/usr/lib/python2.7/site-packages/oz/Guest.py", line 1017, in
_wait_for_guest_boot
        raise oz.OzException.OzException("Timed out waiting for guest to boot")
    oz.OzException.OzException: Timed out waiting for guest to boot

cheers,
Pádraig.

Ug, yes.  I'll send an updated patch to the website.

Yeah, sorry, that was a typo on my part; I only built F-15 packages this time.

Hm, probable SELinux problem.  I hadn't seen that, but I'll try it out
and see what happens.

Thanks for trying,
Chris

Pádraig,
     Interestingly enough, things work just fine for me in F-15, but I
run into problems on F-16 like you did.  I'm tempted to call it a
libvirt bug in F-16, but I'm not entirely certain of that.  I'll see
if I can find sometime this weekend to narrow it down a bit.

Thanks,
Chris
