ïOkay well, the problem occurs under amd64 system only. The problem is around the marshal of the virConnectCredential structure. 
I have marshalled it as this:

///<summary>
   /// Credential structure
   ///</summary>
   [StructLayout(LayoutKind.Sequential)]
   public struct virConnectCredential
   {
       ///<summary>
       /// One of virConnectCredentialType constants
       ///</summary>
       [MarshalAs(UnmanagedType.I4)]
       public virConnectCredentialType type;
       ///<summary>
       /// Prompt to show to user
       ///</summary>
       private IntPtr prompt;
       ///<summary>
       /// Additional challenge to show
       ///</summary>
       private IntPtr challenge;
       ///<summary>
       /// Optional default result
       ///</summary>
       private IntPtr defresult;
       ///<summary>
/// Result to be filled with user response (or defresult). An IntPtr to a marshalled allocated string 
       ///</summary>
       private IntPtr result;
       ///<summary>
       /// Length of the result
       ///</summary>
       [MarshalAs(UnmanagedType.U4)]
       public uint resultlen;
       ///<summary>
       /// Prompt to show to user
       ///</summary>
       public string Prompt
       {
           get
           {
               return Marshal.PtrToStringAnsi(prompt);
           }
       }
       ///<summary>
       /// Additional challenge to show
       ///</summary>
       public string Challenge
       {
           get
           {
               return Marshal.PtrToStringAnsi(challenge);
           }
       }
       ///<summary>
       /// Optional default result
       ///</summary>
       public string Defresult
       {
           get
           {
               return Marshal.PtrToStringAnsi(defresult);
           }
       }
       ///<summary>
       /// Result to be filled with user response (or defresult).
       ///</summary>
       public string Result
       {
           get
           {
               return Marshal.PtrToStringAnsi(result);
           }
           set
           {
result = NativeFunctions.StrDup(Marshal.StringToHGlobalAnsi(value)); 
           }
       }
   }
The strange thing is that I have made test with this marshaling, it always work with on x86 (fedora or ubuntu) and failed marshaling on amd64 (ubuntu or fedora) 

Anyone have an idea ?

Arnaud

I think I have Mono AMD64 here as I'm running the AMD64 version of Ubuntu 10.04. 

Matthias

2010/10/21  <arnaud.champion@xxxxxxxxxx>:

Another question, are you using a x86 or a amd64 version of mono ?

Solved, I have compiled with --disable-nls and I have reproduced the
problem, but I have a lot of difficulties to find the solution, for now... 
but I continue to search.

I have a compile problem under ubuntu 10.04.
I have used the git libvirt version. autogen run fine (I haven't used any

argh, esx support is not compiled by default in ubuntu. I have to take
the time to compile libvirt.

I'm testing on Ubuntu 10.04 with

mono 2.4.4~svn151842-1ubuntu4
monodevelop 2.2.1+dfsg-1ubuntu2

and libvirt and libvirt-csharp from git.

It seems that the marshaling of the virConnectCredential structure
failed,
but I only said that by view your debug traces. Can you say me which
are the
environment of Mono (which version of Mono, which MonoDevelop, these
kind of
things) ? because I have no idea about what's going wrong, I have to
reproduce the case on my system to debug correctly.

The transport shouldn't make a difference. To make it work with
HTTPS
you'll have to replace the self-signed certificates on the ESX
server
or tell libvirt to disable server certificate checks using:

 esx://192.168.0.17/?no_verify=1

Matthias

2010/10/20  <arnaud.champion@xxxxxxxxxx>:


Okay I'll take a look, is the transport in http ? (just to be
curious, I
haven't been able to make it work in https)

I pushed this one too and did a patch remove trailing white spaces 
on
top.

I tested the bindings by successfully compiling and using the
virConnectOpen example on Linux in MonoDevelop.

The virConnectOpenAuth example throws a
System.NullReferenceException
when I try to connect to an ESX server.

GLib.ExceptionManager.UnhandledException
to handle the exception.
