[vbox-dev] Is there issue with IProgress_waitForCompletion?

[DavidW]

I just did some more tests, found it is not the waitForCompletion. It should
be the SessionObject related, here is what I do

 

1, IWebsessionManager_getSessionObject 

2, power up virtual machine 1 - IVirtualBox_openRemoteSession 

3, ISession_close

4, IWebsessionManager_getSessionObject

5, power up virtual machine 2 - IVirtualBox_openRemoteSession

6, ISession_close

 

I randomly get error on step 5, the error is "The given session is already
open or being opened"

 

I found the session object id I get after step 1 and step 4 are the same, so
it seems keep get the same session. That may explain why I get the error.

 

I then try the following

 

1, IWebsessionManager_logon

2, IWebsessionManager_getSessionObject 

3, power up virtual machine 1 - IVirtualBox_openRemoteSession 

4, ISession_close

5,IWebsessionManager_logoff

6,IWebsessionManager_logon

7, IWebsessionManager_getSessionObject

8, power up virtual machine 2 - IVirtualBox_openRemoteSession

9, ISession_close

10,IWebsessionManager_logoff

 

So I  logon/off for each call, this time, I get different session object id,
and doesn't look like I get the error anymore.

 

But it doesn't sound very reasonable to me, do I have to logon/logoff for
each action?

 

Any help will be appreciated.

 

Thanks

I found IProgress_waitForCompletion not always finish right, for example,
when I call IConsole_saveState, I will call IProgress_waitForCompletion and
set timeout to 30000, and then I will call IProgress_getPercent to check, I
don't get 100 in return. And then it affects the next action I do to the VM.
Any idea I may do wrong here?
