我正在尝试编写几个用于与 Microsoft Virtual Server 2005 R2 SP1 交互的 NAnt 任务,并且我已经在“通过 PowerShell 控制虚拟服务器”帖子中提取了“Virtual PC Guy 的 WebLog”中的代码。
它不起作用:调用 CreateVirtualMachine 时总是失败:
System.Runtime.InteropServices.COMException (0x80070542): Either a required impersonation level was not provided, or the provided impersonation level is invalid. (Exception from HRESULT: 0x80070542)
at Microsoft.VirtualServer.Interop.VMVirtualServerClass.CreateVirtualMachine(String configurationName, String configurationPath)
我的代码如下:
var virtualServer = new VMVirtualServerClass();
SetSecurity(virtualServer);
var virtualMachine = virtualServer.CreateVirtualMachine("TEST",
@"D:\Virtual Server\TEST.vmc");
...其中 SetSecurity 定义如下:
private static void SetSecurity(object dcomObject)
{
IntPtr pProxy = Marshal.GetIUnknownForObject(dcomObject);
int hr = CoSetProxyBlanket(pProxy,
RPC_C_AUTHN_DEFAULT,
RPC_C_AUTHZ_DEFAULT,
IntPtr.Zero,
RPC_C_AUTHN_LEVEL_PKT_PRIVACY,
RPC_C_IMP_LEVEL_IMPERSONATE,
IntPtr.Zero,
EOAC_DYNAMIC_CLOAKING);
Marshal.ThrowExceptionForHR(hr);
}
private const uint RPC_C_AUTHN_NONE = 0;
private const uint RPC_C_AUTHN_WINNT = 10;
private const uint RPC_C_AUTHN_DEFAULT = 0xFFFFFFFF;
private const uint RPC_C_AUTHZ_NONE = 0;
private const uint RPC_C_AUTHZ_DEFAULT = 0xFFFFFFFF;
private const uint RPC_C_AUTHN_LEVEL_DEFAULT = 0;
private const uint RPC_C_AUTHN_LEVEL_PKT_PRIVACY = 6;
private const uint RPC_C_IMP_LEVEL_IDENTIFY = 2;
private const uint RPC_C_IMP_LEVEL_IMPERSONATE = 3;
private const uint EOAC_NONE = 0;
private const uint EOAC_DYNAMIC_CLOAKING = 0x40;
private const uint EOAC_DEFAULT = 0x0800;
[DllImport("Ole32.dll")]
public static extern int CoSetProxyBlanket(IntPtr pProxy,
UInt32 dwAuthnSvc,
UInt32 dwAuthzSvc,
IntPtr pServerPrincName,
UInt32 dwAuthnLevel,
UInt32 dwImpLevel,
IntPtr pAuthInfo,
UInt32 dwCapabilities);
如果我编写一个独立程序并添加对 的调用CoInitializeSecurity
,那么它可以工作。但是,我不想要一个独立的程序——我想要一组 NAnt 任务(所以是一个 DLL),并且我不想调用CoInitializeSecurity
,因为无法保证其他一些 NAnt 任务不会调用它已经。
有没有人有这个工作?
