Some news on the Hyper-V support under Samba ...

[Richard Sharpe]

Hi folks,

Earlier in the week DB approached me and indicated that he had gotten
a certain way with Hyper-V support for Samba after applying my earlier
patches etc but was stuck with one more thing. We chatted about it and
I said I would look at implementing that extra thing if he didn't.

He went ahead and wrote something and got it working, but it turns out
that the key piece in the current master is to hack out the following
test:

----------------------------------------------------------
--- a/source3/smbd/smb2_create.c
+++ b/source3/smbd/smb2_create.c
@@ -910,12 +910,14 @@ static struct tevent_req *smbd_smb2_create_send(TALLOC_CTX
 *mem_ctx,
  }
  }

+#if #SVHDX_NOT_WANTED
  if (svhdx != NULL) {
  /* SharedVHD is not yet supported */
  tevent_req_nterror(
  req, NT_STATUS_INVALID_DEVICE_REQUEST);
  return tevent_req_post(req, ev);
  }
+#endif

  /* these are ignored for SMB2 */
  in_create_options &= ~(0x10);/* NTCREATEX_OPTIONS_SYNC_ALERT */
------------------------------------------------------------------

In any event, with these clues, we now have:

------------------------------------------------------------------
PS C:\Users\Administrator> net use
New connections will not be remembered.


Status       Local     Remote                    Network

-------------------------------------------------------------------------------
OK           Z:        \\192.168.2.17\sample     Microsoft Windows Network
The command completed successfully.

PS C:\Users\Administrator> New-VM -Name rjstest2 -MemoryStartupBytes
256MB -NewVHDPath Z:\RJSTEST3.VHDX -NewVHDSizeBytes 10000000000

Name     State CPUUsage(%) MemoryAssigned(M) Uptime   Status

rjstest2 Off   0           0                 00:00:00 Operating normally
------------------------------------------------------------------

I have also seen a screen-shot of a VM starting ...

Attached is a patch that locates all the bits and pieces that might
help, although Windows seems to recover from them not being available
and does not even need the resiliency patch.

Many thanks to DB for bring this to my attention. When he gives me
approval I will supply his name since he deserves credit for finally
cracking this nut.
