libguestfs web seminar – this Friday

Updated x 4

Download this handout which contains slides that accompany the talk.

I’ll be holding a libguestfs live “webinar” this Friday, 18th November 2011 at 16:00 UTC.

To convert the time to your location, do:

date -d '2011-11-18 16:00Z'

The programme will include:

  • An introduction to libguestfs features.
  • Live demonstrations of guestfish, a Python program, inspection, and image resizing.
  • An overview of major new features in RHEL 6.3.
  • The opportunity to ask questions on any technical topic related to libguestfs.

Don’t worry if you can’t make it or if you can’t get Webex working. It will all be recorded and put online in an open format soon afterwards.

This is a Webex conference. See the end of this posting for details on how to get this working on Linux (hint: it’s not simple).

Webex tips:

Try the Webex test meeting: http://www.webex.com/test-meeting.html

Webex needs a Java plugin for your browser, but be warned that it’s a trial to get all the extra things you need. In particular if it doesn’t work, go into $HOME/.webex/*, locate all *.so files, and install all the missing 32 bit libraries they depend on, ie:

cd ~/.webex
find -name '*.so' | xargs ldd | grep 'not found'

# the gcj version number may be different in the next line
sudo yum install /usr/lib/gcj-4.6.2/libjawt.so

# This list of libraries is taken from the ones needed
# by webex on my machine.  Some "No package ... available"
# warnings are expected here.
sudo yum install {/lib,/usr/lib}/{libasound.so.2,libatk-1.0.so.0,libc.so.6,libdl.so.2,libfontconfig.so.1,libfreetype.so.6,libgcc_s.so.1,libgdk_pixbuf-2.0.so.0,libgdk-x11-2.0.so.0,libglib-2.0.so.0,libgmodule-2.0.so.0,libgobject-2.0.so.0,libgtk-x11-2.0.so.0,libm.so.6,libnsl.so.1,libpango-1.0.so.0,libpangoft2-1.0.so.0,libpangox-1.0.so.0,libpangoxft-1.0.so.0,libpng12.so.0,libpthread.so.0,libresolv.so.2,librt.so.1,libstdc++.so.6,libuuid.so.1,libX11.so.6,libXext.so.6,libXft.so.2,libXi.so.6,libXmu.so.6,libXrender.so.1,libXt.so.6,libXtst.so.6,libXv.so.1,libz.so.1}

The new Red Hat Enterprise Linux Virtualization Getting Started Guide, which I worked on, is essential reading if you want to find out how to start out using KVM on RHEL 6.

Coming up: libguestfs webinar

Next month, probably around the middle of October 2011 (but the date is not finalized) I will be giving a “world wide webinar” about libguestfs and the virt tools.

This is going to be mainly about RHEL, but it will also be relevant for Fedora/Debian/Ubuntu users. It’ll be a gentle introduction: technical, but you won’t need to know anything about libguestfs. It’s not a marketing thing.

The conference will be open to everyone. The way these work is you call in to a conference phone number. There will be numbers announced for each country, plus for a few countries there may be toll-free numbers. Also if you have Webex you will be able to follow what’s happening on my desktop at the same time.

There will be an opportunity to ask questions at the end.

The call will be recorded and archived — more details about that afterwards.

Red Hat Enterprise Linux 6

Looks like RHEL 6 is out.

Of course I’ve been using it for a while and it’s great.

This version has libguestfs-1.2.7-1.24.el6 (with backports) from back around April/May (when we started to stabilize and QA everything). Have fun using it, and when RHEL 6.1 ships it will come with libguestfs 1.6 which is much faster and more full-featured.
