?Okay, the NodeInfo structure must be marshled in this way to make it works : /// <summary> /// Structure to handle node informations /// </summary> [StructLayout(LayoutKind.Sequential)] public class NodeInfo { /// <summary> /// String indicating the CPU model. /// </summary> [MarshalAs(UnmanagedType.ByValTStr, SizeConst = 32)] public string model; /// <summary> /// Memory size in kilobytes /// </summary> [MarshalAs(UnmanagedType.SysUInt)] public UIntPtr memory; /// <summary> /// The number of active CPUs. /// </summary> [MarshalAs(UnmanagedType.SysUInt)] public UIntPtr cpus; /// <summary> /// Expected CPU frequency. /// </summary> [MarshalAs(UnmanagedType.SysUInt)] public UIntPtr mhz; /// <summary> /// The number of NUMA cell, 1 for uniform mem access. /// </summary> [MarshalAs(UnmanagedType.SysUInt)] public UIntPtr nodes; /// <summary> /// Number of CPU socket per node. /// </summary> [MarshalAs(UnmanagedType.SysUInt)] public UIntPtr sockets; /// <summary> /// Number of core per socket. /// </summary> [MarshalAs(UnmanagedType.SysUInt)] public UIntPtr cores; /// <summary> /// Number of threads per core. /// </summary> [MarshalAs(UnmanagedType.SysUInt)] public UIntPtr threads; } I will put it in next patches.

So you should anything like : Errors.Error err = Errors.GetLastError(); MessageBox.Show(err.Message); For the NodeInfo structure, I think the problem is the same that was for DomainInfo, I'll check marshaling. Then respond you with the correct infos. Arnaud PS : can you also put libvirt-list(a)redhat.com in copy of your mails, to keep everyone in the loop ?

Code: NodeInfo aNodeInfo = new NodeInfo(); if (Node.GetInfo(con, aNodeInfo) < 0) { //MessageBox.Show("Node Info Error"); MessageBox.Show(Errors.GetLastError().ToString()); return 0f; } I'm sure con != IntPtr.Zero. I tried to use Errors.GetLastError(), it returns int. But I don't know what to do with it. So, any suggestions ?

?Hi, I think the solution is in the last patches I have send (which are not yet in the git). Have you tried the NodeInfoStructure I have sended yesterday ?

I made a guess that maybe it was like this: Error err = Errors.SaveLastError(); MessageBox.Show("Get Info error: " + err.Message); It can be compiled but "err.Message" has nothing in it. Did I make a wrong assumption?
