2007-11-28 13:22:16 +00:00
of some of its operating systems available to
< a href = "http://msdn.microsoft.com/" > MSDN subscribers< / a > .
We used Windows 2008 Server for testing, virtualized under
Linux using KVM-53 (earlier versions of KVM and QEMU won't
run recent versions of Windows because of lack of full ACPI
support, so make sure you have the latest KVM).

2007-11-28 13:22:16 +00:00
Make sure you have 10 GB free to install most Cygwin packages,
although if you pare down the list of dependencies you may
2008-04-23 17:08:31 +00:00
get away with much less. < / li > < li > A network connection for Windows, since Cygwin downloads packages
from the net as it installs. < / li > < li >

These are the steps to take to compile libvirt from
source on Windows:
2008-04-23 17:08:31 +00:00
< / p >
< ol > < li >
< p > Run Cygwin
2007-11-28 13:22:16 +00:00
< a href = "http://www.cygwin.com/setup.exe" > setup.exe< / a > .
When it starts up it will show a dialog like this:

screen for selecting packages:< / p >

2007-11-28 13:22:16 +00:00
The user interface here is very confusing. You have to
click the "recycling icon" as shown by the arrow:

through several states such as "Install", "Reinstall", "Keep",
"Skip", "Uninstall", etc.

Or you can download the
< a href = "ftp://libvirt.org/libvirt/win32/sunrpc-4.0-dll.patch" > source patch< / a >

The above steps should also build and install Python modules.
However for reasons which I don't fully understand, Python won't
look in the
non-standard < code > /usr/local/lib/python*/site-packages/< / code >
directory by default so you may need to set the environment
variable PYTHONPATH:
< / p >
2008-04-23 17:08:31 +00:00
< pre >
2007-11-29 16:21:52 +00:00
export PYTHONPATH=/usr/local/lib/python2.5/site-packages
< / pre >
2008-04-23 17:08:31 +00:00
< p >
2007-11-29 16:21:52 +00:00
(Change the version number to your version of Python). You
can test Python support from the command line:
< / p >
2008-04-23 17:08:31 +00:00
< pre >
2007-11-29 16:21:52 +00:00

The most common failure will be with < code > import libvirt< / code >
which usually indicates that either < code > PYTHONPATH< / code > is
wrong or a DLL cannot be loaded.
