[libvirt] virDomainInfo marshalling prolem

?Hi, I am working on the marshaling of the virDomainInfo structure. I have marshalled it in this way : /// <summary> /// Structure to handle domain informations /// </summary> [StructLayout(LayoutKind.Sequential)] public class DomainInfo { /// <summary> /// The running state, one of virDomainState. /// </summary> private Byte state; /// <summary> /// The maximum memory in KBytes allowed. /// </summary> public int maxMem; /// <summary> /// The memory in KBytes used by the domain. /// </summary> public int memory; /// <summary> /// The number of virtual CPUs for the domain. /// </summary> public short nrVirtCpu; /// <summary> /// The CPU time used in nanoseconds. /// </summary> public long cpuTime; /// <summary> /// The running state, one of virDomainState. /// </summary> public DomainState State { get { return (DomainState)state; } } } It work fine in 32 bits, but not in 64 bits, it seems that packing in 64 bits is different so infos are not in order. Am I right ? Regards, Arnaud
