[libvirt] C# bindings need and advice from the experts
?Hi,
I'm working on C# bindings. The goal is to obtain a more C# API for the API
users.
So I have create object for libvirt familly function (an object Connect,
Domain, Storage and so on).
All is almost done, but I need and advice about the way to handle object
properties. For example, for the Connect object, I expose a "RunningDomains"
property that can be used in this manner :
Connect myConn = new Connect("qemu+tcp://192.168.220.198/system");
List runningDomains = myConn.RunningsDomains;
In the Connect object, the property "RunningDomains" is coded in this :
///
/// Get the list of running domains
///
public List RunningDomains
{
get
{
if (_conn == IntPtr.Zero) return null;
int nbRunningDomain = NumOfDomains(_conn);
int[] runningDomainIds = new int[nbRunningDomain];
ListDomains(_conn, runningDomainIds, nbRunningDomain);
return runningDomainIds.Select(id => new
Domain(Domain.LookupByID(_conn, id), this)).ToList();
}
}
So the property call "virConnectNumOfDomains" and "virConnectListDomains" each
time the property is called. And I don't know if it is a good thing. The other
way, is to keep the list in the Connect object and handle domain adding or
removing in this via callbacks. This avoid multiple call to the librar.
Any advice ?
Regards,
Arnaud

good idea.

That's correct, regsvr32 is for registering COM components. It has nothing to do with the runtime linker finding the DLLs. In order to have libvirt-0.dll available for applications it must either be in the same directory as the application's binary (having it in the working directory might work too), or it must be in the PATH. But putting \bin in the PATH pollutes the global DLL namespace with common DLLs like zlib1.dll. This makes DLL hell worse. Strawberry Perl avoids this by making the DLL name unique to Strawberry Perl by posfixing them with an underscore. I just hacked a small C program that can rewrite the DLL import tables. This allows to easily prefix all DLLs in \bin (expect libvirt-0.dll and libvirt-qemu-0.dll) without touching all the buildsystems for those DLLs to rename them. Instead of this filenames in \bin: iconv.dll intl.dll libcurl-4.dll libgcrypt-11.dll libgnutls-26.dll libgpg-error-0.dll libportablexdr-0.dll libtasn1-3.dll libvirt-0.dll libvirt-qemu-0.dll libxml2-2.dll virsh.exe zlib1.dll we can have this ones: libvirt-0.dll libvirt-qemu-0.dll virsh.exe _lv_iconv.dll _lv_intl.dll _lv_libcurl-4.dll _lv_libgcrypt-11.dll _lv_libgnutls-26.dll _lv_libgpg-error-0.dll _lv_libportablexdr-0.dll _lv_libtasn1-3.dll _lv_libxml2-2.dll _lv_zlib1.dll Or with any other prefix/postfix with up to 4 characters.

I have included the coverage also. regards, Arnaud Okay, I pushed the 0001-Correct-virGetLastError-marshaling.patch. The 0001-Add-sample-virDomainStats.patch depends on the 0001-Correct-virDomainBlockStats-virDomainInterfaceStats-.patch. In 0001-Correct-virDomainBlockStats-virDomainInterfaceStats-.patch you used UnmanagedType.SysUInt to marshal a ulong in NodeInfo. This fixes the problem with long having different sizes on 32bit and 64bit systems. But for some reason you used UnmanagedType.I8 to marshal long in DomainInterfaceStatsStruct and DomainBlockStatsStruct. I think this is wrong on 32bit systems and should be UnmanagedType.SysInt instead, shouldn't it? Also this comment "// TODO virDomainMemoryStats : Currently disabled in libvirt" is wrong. It's not disabled in libvirt, it's disabled in QEMU. 0001-Forgot-comments-on-new-sample.patch is just an incremental fix for 0001-Add-sample-virDomainStats.patch and I'll squash the fix into it when I can push it.

Well, I removed the ">", and yes it goes a few steps further but it still fail
to apply
the error msg is :
fatal: sha1 information is lacking or useless (Domain.cs).
Repository lacks necessary blobs to fall back on 3-way merge.
Cannot fall back to three-way merge.
so what can I do?

For some reason the first line in his patches has ">" in front of the

Re: [libvirt] SPAM-LOW: Domain.GetInfo error
?Hi,
In fact, when you compile libvirt with mingwin/msys, the binaries are compiled
in 32 bits, even it runs on a 64 bits system. Accordingly, C# bindings must be
targeted as x86 (32 bits) when compiling them. This isn't a problem for a 64
bits application which use bindings, .Net make the trick to make it works.
I haven't made any test with xen (I haven't xen) but if your sample works, it
means libvirt is compiled with xen support.
Happy halloween to you also.

Hi,
Thanks for your reply.
It works with the patch you provide in last letter.
But I don't understand "x86 target" you mentioned, does it mean if I want to
make the code run, the server which runs xend & libvirtd must be a x86 arch,
not a x64 arch?
As to the question "are you sure also that libvirt dll is compiled with xen
support ?"
I just follow the instructions on http://github.com/photron/msys_setup, without
the ESX support, I think it should support Xen, though it isn't write in
explicit.
Anyway, at least it's working. Thanks for your reply.

Hi,
So, at first, are you sure that conn != IntPtr.Zero and pDomain != IntPtr.Zero.
if both pointer are ok, can you please check the DomainInfo marshal, I have
just sended patch today around this structure, and I think the patch is not yet
pushed to the git.
The DomainInfo structure must be marshaled in this way :
///
/// Structure to handle domain informations
///
[StructLayout(LayoutKind.Sequential)]
public class DomainInfo
{
///
/// The running state, one of virDomainState.
///
private byte state;
///
/// The maximum memory in KBytes allowed.
///
[MarshalAs(UnmanagedType.SysUInt)]
public UIntPtr maxMem;
///
/// The memory in KBytes used by the domain.
///
[MarshalAs(UnmanagedType.SysUInt)]
public UIntPtr memory;
///
/// The number of virtual CPUs for the domain.
///
public ushort nrVirtCpu;
///
/// The CPU time used in nanoseconds.
///
[MarshalAs(UnmanagedType.SysUInt)]
public UIntPtr cpuTime;
///
/// The running state, one of virDomainState.
///
public DomainState State { get { return (DomainState)state; } }
}
Also, another important thing change : the libvirt bindings project must have
an x86 target to make this marshaling working. This is also in the patch.
Another thing, you can also use Errors.GetLastErro() method to identify the
problem, it return an error class which can inform you about the problem.
Best regards,
Arnaud

Re: [libvirt] SPAM-LOW: Domain.GetInfo error
?Hi,
So, at first, are you sure that conn != IntPtr.Zero and pDomain != IntPtr.Zero.
if both pointer are ok, can you please check the DomainInfo marshal, I have
just sended patch today around this structure, and I think the patch is not yet
pushed to the git.
The DomainInfo structure must be marshaled in this way :
///
/// Structure to handle domain informations
///
[StructLayout(LayoutKind.Sequential)]
public class DomainInfo
{
///
/// The running state, one of virDomainState.
///
private byte state;
///
/// The maximum memory in KBytes allowed.
///
[MarshalAs(UnmanagedType.SysUInt)]
public UIntPtr maxMem;
///
/// The memory in KBytes used by the domain.
///
[MarshalAs(UnmanagedType.SysUInt)]
public UIntPtr memory;
///
/// The number of virtual CPUs for the domain.
///
public ushort nrVirtCpu;
///
/// The CPU time used in nanoseconds.
///
[MarshalAs(UnmanagedType.SysUInt)]
public UIntPtr cpuTime;
///
/// The running state, one of virDomainState.
///
public DomainState State { get { return (DomainState)state; } }
}
Also, another important thing change : the libvirt bindings project must have
an x86 target to make this marshaling working. This is also in the patch.
Another thing, you can also use Errors.GetLastErro() method to identify the
problem, it return an error class which can inform you about the problem.
Best regards,
Arnaud
PS : are you sure also that libvirt dll is compiled with xen support ?

Dear Arnaud
Here is my test code. Function Domain.GetInfo return -1 and I don't know where
is the mistake.
Would you do me a favor to point out the problem? Thank you!
Code:
IntPtr conn = Connect.Open("xen+tcp://192.168.0.1?no_verify=1");
String DomainName = e.Node.Text;
IntPtr pDomain = Domain.LookupByName(conn, DomainName);
DomainInfo aInfo = new DomainInfo();
if (Domain.GetInfo(pDomain, aInfo) == -1)
{
MessageBox.Show("Get Info error");
return;

Re: [libvirt] Hyper-V driver ?
?Interesting... You a Hyper-V user ;) -- From: "Michael Sievers" Sent: Saturday, October 30, 2010 2:48 PM To: Subject: Re: [libvirt] Hyper-V driver ? Hi ! My name ist Michael Sievers. I am studying computer science at Paderborn/Germany. I worked together with Matthias Bolte on a project here at Paderborn, where we evaluated the possibility of controlling Microsoft Hyper-V using WS-Management through libvirt (which is actually called WinRM on Windows). At the end of the project I had a very minimalistic libvirt driver, which was just able to connect to Hyper-V and to power cycle a given VM. Unfortunately, the project stopped at this point and so did my efforts on this topic. Since developing a full fledged Hyper-V driver for libvirt a very time consuming effort I am currently searching for a way to do so which incorporates with my study. At this point I can tell you the following - it is possible to control Hyper-V using libvirt using WS-Management - this is actually the only way (as far as I know) to control Hyper-V from non-Windows hosts, as you can not use WMI (which is Hyper-V main API) from non Windows hosts directly - WS-Management is the bridge to talk to WMI from non-Windows hosts as there are implementations such as OpenWSman which you can use - doing complicated things in WS-Management (e.g. calling a function with reference parameters) is not well documented and that's why a pain to implement The last point was the main reason, why the development stopped after implementing the power cycling. Last week I talked to my professor about this and he told me, that maybe there is a company (unfortunately I can't tell you the name) which is willing to support this effort financially, which would give me to opportunity to resume development. But sadly this not for sure, yet. I will inform you (the libvirt mailing list) during the next two weeks about the results. Cheers Michael Sievers P.S. Sorry for sending this mail three times to libvir-list as I did not remembered that I once subscribed with a different email address. 2010/10/30 Justin Clift : On 10/30/2010 03:21 AM, Daniel Veillard wrote: "WS-Management Protocol" points to http://msdn.microsoft.com/en-us/library/aa384470%28v=VS.85%29.aspx where "Web Services for Management (WS–Management)." points to http://www.dmtf.org/sites/default/files/standards/documents/DSP0226.pdf which says Page Not Found I find that lovely ...

Re: [libvirt] virDomainInfo marshalling prolem
Hi,
I think I got it. I think I have to marshal in this manner :
[StructLayout(LayoutKind.Sequential)]
public class DomainInfo
{
private byte state;
[MarshalAs(UnmanagedType.SysUInt)]
public UIntPtr maxMem;
[MarshalAs(UnmanagedType.SysUInt)]
public UIntPtr memory;
public ushort nrVirtCpu;
[MarshalAs(UnmanagedType.SysUInt)]
public UIntPtr cpuTime;
public DomainState State { get { return (DomainState)state; } }
}
And I also have to set the target of the LibvirtBindings project to x86. Why
? The compilation of libvirt under mingwin produce a 32bits binary, so I
MUST marshal libvirt with a 32bits schema. That doesn't break compatibility
with 64bits project using bindings, and this allow the usage of the
attribute [MarshalAs(Unamanged.SysUint)]. This attribute specify the target
schema for bindings at runtime. In this way, under 64bits systems, it takes
ulong on 8 bytes, and on 4 bytes under 32bits.
This make the bindings work under Windows/mono(32bits, as the mono
exxcutable is in 32bits, even if my system is 64bits), works also under
Windows/.Net(64bits) and works under Ubuntu/Mono(64 bits).
Any suggestion ?

Arnaud

This basically works, but probably doesn't feel very C#'ish. I think we might complete the bindings at this level. Once that basic thin layer is done and all the hard problems are solved - like the heap issue in the auth callback (has a workaround) or the integer width on different platforms problem with the virDomainInfo struct - then we can wrap this "first level" bindings into a more C#'ish way with instances of the Domain class representing an underlying virDomainPtr etc. At that level we can use the GC and let it collect domain objects. But we'll still keep the explicit Free() methods as in the Java bindings, because I think that the C# GC - as most/all GC languages - doesn't guarantee calling finalizers/destructors at all and we might end up with leaked underlying objects.

In the struct looks like this
struct _virDomainInfo {
unsigned char state;/* the running state, one of
virDomainState */
unsigned long maxMem; /* the maximum memory in KBytes allowed
*/
unsigned long memory; /* the memory in KBytes used by the
domain */
unsigned short nrVirtCpu; /* the number of virtual CPUs for the
domain */
unsigned long long cpuTime; /* the CPU time used in nanoseconds */
};
but you mapped unsigned long to int. First of all you should map this
to an unsigned type. You also lost the unsigned for some other
members.
The problem probably is that long in C is 32bit on a 32bit platform an
64bit on a 64bit platform. You mapped it to int that is always 32bit
in C#, when I looked it up correctly.
Not quite. Windows just had to do things diffrently on 64-bit and so
used
the LLP64 model instead of LP64 used by the rest of the world :-(
http://technet.microsoft.com/en-us/library/bb496995.aspx
In the UNIX/64 data model:
The size of int is 32 bits and the size of long and pointers is 64
bits.
In the Win64 model:
The size of int and long is 32 bits; the size of int64 (new type)
and pointers is 64 bits.

Ah yes. I forgot about that one. So this gets even more complicated
when you want to get the C# bindings working on 32 and 64 bit Windows

Hi,
I have finally find the problem with examples on mono compiled in 64 bits. The
problem was the "ToInt32" method of an IntPtr which failed on mono 64 bits
(have to use ToInt64 instead).
This path solve this problem.
Also, I have put marshaling complexity of the ConnectOpenAuth callback in
bindings, this make the callback of ConnectOpenAuth more simple to achieve the
authentification. In the example, the callback is treated like this :
private static int AuthCallback(ref ConnectCredential[] creds, IntPtr cbdata)
{
AuthData authData = (AuthData)Marshal.PtrToStructure(cbdata,

foreach (ConnectCredential cred in creds)

break;

// Fill the password
cred.Result = authData.password;
break;
default:
return -1;
}
}

}
The bindings user has no marshaling to do, and believe me, it's simpler.
Finally, this patch finalize renaming.

Subject: [libvirt] [libvirt-csharp][PATCH] Make examples works on monocompiled
in 64 bits, simply the ConnectOpenAuth process,and finalise renaming
Hi,
I have finally find the problem with examples on mono compiled in 64 bits. The
problem was the "ToInt32" method of an IntPtr which failed on mono 64 bits
(have to use ToInt64 instead).
This path solve this problem.
Also, I have put marshaling complexity of the ConnectOpenAuth callback in
bindings, this make the callback of ConnectOpenAuth more simple to achieve the
authentification. In the example, the callback is treated like this :
private static int AuthCallback(ref ConnectCredential[] creds, IntPtr cbdata)
{
AuthData authData = (AuthData)Marshal.PtrToStructure(cbdata,
typeof(AuthData));
foreach (ConnectCredential cred in creds)
{
switch (cred.type)
{
case ConnectCredentialType.VIR_CRED_AUTHNAME:
// Fill the user name
cred.Result = authData.user_name;
break;
case ConnectCredentialType.VIR_CRED_PASSPHRASE:
// Fill the password
cred.Result = authData.password;
break;
default:
return -1;
}
}
return 0;
}
The bindings user has no marshaling to do, and believe me, it's simpler.
Finally, this patch finalize renaming.

Re: [libvirt] [PATCH] C# Bindings - rename classes fromvirConnectto Connect, virDomain to Domain, etc...
Okay well, the problem occurs under amd64 system only. The problem is
around the marshal of the virConnectCredential structure.
I have marshalled it as this:
///
/// Credential structure
///
[StructLayout(LayoutKind.Sequential)]
public struct virConnectCredential
{
///
/// One of virConnectCredentialType constants
///
[MarshalAs(UnmanagedType.I4)]
public virConnectCredentialType type;
///
/// Prompt to show to user
///
private IntPtr prompt;
///
/// Additional challenge to show
///
private IntPtr challenge;
///
/// Optional default result
///
private IntPtr defresult;
///
/// Result to be filled with user response (or defresult). An IntPtr
to a marshalled allocated string
///
private IntPtr result;
///
/// Length of the result
///
[MarshalAs(UnmanagedType.U4)]
public uint resultlen;
///
/// Prompt to show to user
///
public string Prompt
{
get
{
return Marshal.PtrToStringAnsi(prompt);
}
}
///
/// Additional challenge to show
///
public string Challenge
{
get
{
return Marshal.PtrToStringAnsi(challenge);
}
}
///
/// Optional default result
///
public string Defresult
{
get
{
return Marshal.PtrToStringAnsi(defresult);
}
}
///
/// Result to be filled with user response (or defresult).
///
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 ?
Regards,
Arnaud

I think I have Mono AMD64 here as I'm running the AMD64 version of Ubuntu
10.04.
Matthias
2010/10/21 :
Another question, are you using a x86 or a amd64 version of mono ?

here is a new patch. It propose to separate types of function by classes.
For example :
all virConnect[*] (virConnectOpen, virConnectNumOfDomains, etc...)

in the virDomain class.
so we have these classes now :
virConnect
virDomain
virEvent
virInterface
virLibrary
virNetwork
virNode
virSecret
virStoragePool

The 'vir' prefix on C library APIs/structs is just a hack because C

The problem with DllMap, is that it works only under Mono, not under
.Net :(
Well, no problem three. You keep the [DllImport("libvirt-0.dll")] in
the code for .Net, so it works for .Net and add a DllMap that tells
Mono that it should use libvirt.so.0 on Linux instead of libvirt-0.dll
etc. I think this is exactly how DllMap is supposed to be used.

Subject: Re: [libvirt] [PATCH] Change/create solution and project for
Visual
Studio and MonoDevelop for C# bindings
2010/10/19 :
Hi,
here are 2 patches for C# libvirt bindings.
These patches create a new solution/project couple for Visual Studio
2010
with also a sample code and a solution/project couple for MonoDevelop
with a
sample code also.
The sample code have been tested under .Net/Windows, Mono/Windows and
Mono/Linux. And it works, the sample code consist of the using au
virConnectOpenAuth and callback handling. It connect to a URI (I have
made
my tests with ESX hypervisor only) and list domains in a listbox.
So, to summarize, code work under linux or windows, the binary library
name
depends of a project directive (a kind of pragma). When the directive
WINDOWS is declared, DllImport will try to find "libvirt-0.dll" (for
windows) otherwise it looks for "libvirt.so.0" (for linux). For now,
in
the
same manner, when the directive WINDOWS is declared, we find _strdup
in
"msvcrt.dll" otherwise we look in "libc.so.6".
This makes the resulting binary platform dependent. I asked a friend
about this and he suggested to use Mono's dllmap feature [1]. It
allows you to stick with [DllImport("libvirt-0.dll")] in the code for
.Net and have Mono use libvirt.so.0 on Linux and libvirt.dylib on OSX.
This result in a platform independent binary regarding this issue.
[1] http://www.mono-project.com/Config_DllMap
I'm currently trying to remove strdup call by Custom Marshaling but it
seems
that .Net (or Mono anyway) doesn't allow to use custom marshaler with
structure (and we need it for virConnectCredential structure). If
anyone
had
an idea...
Regarding this issue my friend suggested to stop libvirt from taking
ownership of cred.result. We could do that by making
virConnectOpenAuth take a new VIR_CONNECT_COPY_CRED_RESULT (or
VIR_CONNECT_DONT_FREE_CRED_RESULT or VIR_CONNECT_CONST_CRED_RESULT)
flag that lets libvirt internally strdup() cred.result before passing
it to the driver. That way the C# bindings could pass a managed string
as cred.result and we don't need to Marshal.StringToHGlobalAuto() and
strdup in C# at all.
Or we could make libvirt take a custom free function to free
cred.result instead of free(). That way Marshal.FreeHGlobal could be
used or no free function at all and you pass a managed string to it.
This would probably require a new version of virConnectOpenAuth and I
consider this as too invasive.
Another possibility would be to add a public virAlloc to libvirt that
C# can use to allocate memory that can be freed using free().

The problem with DllMap, is that it works only under Mono, not under .Net
:(
Well, no problem three. You keep the [DllImport("libvirt-0.dll")] in
the code for .Net, so it works for .Net and add a DllMap that tells
Mono that it should use libvirt.so.0 on Linux instead of libvirt-0.dll
etc. I think this is exactly how DllMap is supposed to be used.

Subject: Re: [libvirt] [PATCH] Change/create solution and project for
Visual
Studio and MonoDevelop for C# bindings
2010/10/19 :
Hi,
here are 2 patches for C# libvirt bindings.
These patches create a new solution/project couple for Visual Studio
2010
with also a sample code and a solution/project couple for MonoDevelop
with a
sample code also.
The sample code have been tested under .Net/Windows, Mono/Windows and
Mono/Linux. And it works, the sample code consist of the using au
virConnectOpenAuth and callback handling. It connect to a URI (I have
made
my tests with ESX hypervisor only) and list domains in a listbox.
So, to summarize, code work under linux or windows, the binary library
name
depends of a project directive (a kind of pragma). When the directive
WINDOWS is declared, DllImport will try to find "libvirt-0.dll" (for
windows) otherwise it looks for "libvirt.so.0" (for linux). For now, in
the
same manner, when the directive WINDOWS is declared, we find _strdup in
"msvcrt.dll" otherwise we look in "libc.so.6".
This makes the resulting binary platform dependent. I asked a friend
about this and he suggested to use Mono's dllmap feature [1]. It
allows you to stick with [DllImport("libvirt-0.dll")] in the code for
.Net and have Mono use libvirt.so.0 on Linux and libvirt.dylib on OSX.
This result in a platform independent binary regarding this issue.

I'm currently trying to remove strdup call by Custom Marshaling but it
seems
that .Net (or Mono anyway) doesn't allow to use custom marshaler with
structure (and we need it for virConnectCredential structure). If
anyone
had
an idea...
Regarding this issue my friend suggested to stop libvirt from taking
ownership of cred.result. We could do that by making
virConnectOpenAuth take a new VIR_CONNECT_COPY_CRED_RESULT (or
VIR_CONNECT_DONT_FREE_CRED_RESULT or VIR_CONNECT_CONST_CRED_RESULT)
flag that lets libvirt internally strdup() cred.result before passing
it to the driver. That way the C# bindings could pass a managed string
as cred.result and we don't need to Marshal.StringToHGlobalAuto() and
strdup in C# at all.
Or we could make libvirt take a custom free function to free
cred.result instead of free(). That way Marshal.FreeHGlobal could be
used or no free function at all and you pass a managed string to it.
This would probably require a new version of virConnectOpenAuth and I
consider this as too invasive.
Another possibility would be to add a public virAlloc to libvirt that
C# can use to allocate memory that can be freed using free().
